I am trying to set up a VDI (Virtual Desktop Infrastructure) Server https://askubuntu.com/questions/1567922/i-am-trying-to-set-up-a-vdi-virtual-desktop-infrastructure-server

I am trying to set up a VDI (Virtual Desktop Infrastructure) Server, but everything I try is ineffective because Wayland and KDE require me to click on a Share in the Remote Control requested prompt. This kind of defeats the whole purpose of VDI. My users will not have access to the physical machine. They don't have an iDRAC terminal to go into the VM and click the button. And selecting to save my selection doesnt actually save anything. The next time the user logs out everything is forgotten. This has been a problem now on Wayland based OSs for over 4 years. Is there ANY solution yet. If not I will need to go back to another DE.

I should add that the built-in RDP method does not suit my use case, and please don't recommend changing my workflow that is not actually a solution to the issue.

I don't really like this answer. It would be nice to have something more native, but installing the remote desktop application (eg. RustDesk) by Flatpak, then set this special permission: flatpak permission-set kde-authorized remote-desktop com.rustdesk.RustDesk yes.

Update: Doesn't actually work. I don't get a prompt anymore, but I also don't get an image. Now I understand why some IT teams just stick with Windows, this is kind of BS.

Update 2: Going back to Windows, no matter how much I save in licensing costs, I am losing them in technician hours. Sorry (K)ubuntu. If you can't run RustDesk as a Remote Desktop without issues, then you are not ready for prime time.

Google Chrome frequently crashes and becomes slow on Ubuntu 24.04 despite enough CPU/RAM resources https://askubuntu.com/questions/1567920/google-chrome-frequently-crashes-and-becomes-slow-on-ubuntu-24-04-despite-enough

For about the past week, Google Chrome has been crashing frequently and has also become noticeably slower.

I have not changed my environment or Chrome settings recently. CPU and RAM usage seem to have plenty of headroom, and I do not have an unusually large number of tabs open. In fact, I used to keep more tabs open before without any issues.

There does not seem to be any clear pattern to when the problem occurs. Chrome may freeze or crash while scrolling, but it can also happen when I am not actively interacting with the browser.

I have already tried clearing the cache and browsing history, and I also changed settings such as Memory Saver, but none of these made a noticeable difference.

I could not find any obvious error messages or signs of system instability, so I would appreciate any advice on how to investigate or fix this issue.

I found a similar unresolved issue on Ask Ubuntu.

Environment:

  • OS: Ubuntu 24.04.4 LTS

  • Hardware: Micro-Star International Co., Ltd. MS-7E16

  • CPU: AMD Ryzen 9 7900X × 24

Email address invalidated [closed] https://askubuntu.com/questions/1567919/email-address-invalidated

We have confirmed that there are no firewall restrictions or network blocks on our side. Is there another solution?

Disable Software Install `gnome-software-local-file-flatpak` from autostarting and running in the background in LTS 26.04 https://askubuntu.com/questions/1567918/disable-software-install-gnome-software-local-file-flatpak-from-autostarting-a

This app called Software Install, named gnome-software-local-file-flatpak (also sometimes shows up as just Software, named org.GNOMESoftware) autostarts at login and keeps running in the background.

Resources application showing the Software Install is taking up memory

It is different from App Center snap-store which comes preinstalled. I had to download Software Install from apt (probably came as gnome-software or something), and I used it to install flatpaks (also supports snaps after I turned that setting on) keeps running in the background

App Center is different from Software Install. Software Install has a "grey bag with colored shapes in it" icon

How do I stop Software Install / Software from running in the background? I'm using Ubuntu LTS 26.04 with GNOME 50.

Things I've already tried to no avail:

  1. Turned off automatic updates, show search results from application settings
  2. Turned off startup at login from System Settings > App Permissions
  3. "masked" some service from Terminal following some online results, but it shows that "such a service doesn't exist, creating one". If it is worthwhile to detail this step, let me know as a comment and I'll do it.
  4. Following this answer, could not delete NoDisplay=True from /etc/xdg/autostart/gnome-software-service.desktop because no such file exists.

PS: This is one thing I dislike about Ubuntu. Things change so much and so quickly - there is no persistence in construction. Is distributed disorganization really a fundamental tenet of open source? On the contrary, I think Linux has been most successful in fields where developers have built things based on a unified scheme and purpose. Too many options isn't necessarily a good thing if it comes at the cost of being worried all the time about what's going wrong in your system.

Ubuntu bluetooth https://askubuntu.com/questions/1567917/ubuntu-bluetooth

How to install Ubuntu GNOME Desktop on Kubuntu 26.04 LTS? [duplicate] https://askubuntu.com/questions/1567916/how-to-install-ubuntu-gnome-desktop-on-kubuntu-26-04-lts

I know how very contradictory that statement is, but I wanted to try it again without having to reinstall everything since I moved to KDE Plasma. But when checking what'll happen when I trry installing it alongside KDE Plasma to ensure it won't break anything, I noticed that doing apt --simulate ubuntu-desktop is fine but apt --simulate gnome wants to remove the kubuntu-desktop and kubuntu-settings-desktop packages. Is that fair to be concerned that removing those packages will mess with KDE Plasma?

Is there some way to install GNOME with the stuff that is included on native Ubuntu without it messing with KDE Plasma so that if I decide I really am sure I don't like GNOME, I can just remove it and go back to KDE Plasma like nothing happened? Also out of curiosity sake, what is the difference between ubuntu-desktop and gnome packages?

Stylus on Lenovo Yoga 9 14IRP8 is buggy in vertical tablet mode https://askubuntu.com/questions/1567915/stylus-on-lenovo-yoga-9-14irp8-is-buggy-in-vertical-tablet-mode

My Lenovo Yoga 9 14IRP8 often does not recognize stylus strokes from the Precision Pen 2 when drawing in (mainly vertical, but occasionally also horizontal) tablet/2-in-1 mode, as shown in the picture. I have a hard time to find the origin of this issue. It occurs in different desktop environments (KDE and GNOME) and different distributions (Fedora, Ubuntu 26.04, Ubuntu 24.04). The bugs only happen when my palm rests on the display, but persist when I disable the touchscreen via udev rule:

ACTION=="add|change", SUBSYSTEM=="input", ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_IGNORE_DEVICE}="1"

Kernel: 7.0.0-22-generic

libinput: 1.31.1

Running libinput debug-events reports ultra-short time windows where the pen is detected to be lifted and set back down. Note that the timespans seem too short for a human to lift the pen out of the proximity reach and set it back down, as illustrated by the following snippet:

event6   TABLET_TOOL_TIP              +11.969s      185.73*/103.15* tilt: -12.00 /9.00  pressure: 0.00* up

Does anyone have a similar issue? What is the most likely cause for this?

BCM4322 (14e4:432b) with b43 on Ubuntu 26.04: scans networks but authentication always times out after kernel upgrade https://askubuntu.com/questions/1567914/bcm4322-14e4432b-with-b43-on-ubuntu-26-04-scans-networks-but-authentication

BCM4322 (14e4:432b) with b43 on Ubuntu 26.04 scans WiFi networks, but authentication always times out.

System

  • Computer: Mac Pro 5,1
  • [wireless WiFi card: Broadcom BCM4322]
  • PCI ID: 14e4:432b
  • Ubuntu: 26.04 LTS
  • Current kernel tested: 7.0.0-22-generic
  • Previous kernel tested: 6.17.0-35-generic
  • Driver: b43
  • Firmware: 784.2 (2012-08-15)

Hardware is detected correctly:

lspci -nn | grep -i broadcom
0d:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4322 802.11a/b/g/n Wireless LAN Controller [14e4:432b] (rev 01)

Firmware packages installed:

dpkg -l | grep -E 'b43|bcmwl|broadcom|firmware-b43'

ii  b43-fwcutter
ii  firmware-b43-installer
ii  linux-firmware-broadcom-wireless

My WiFi adapter worked correctly in Ubuntu before.

After a system update, WiFi stopped working.

I previously managed to recover functionality with help from another AI assistant (DeepSeek), but after a later Ubuntu update to 26.04 the problem returned.

Ethernet works perfectly.

Other devices connect to the same router without problems:

  • MacBook
  • Linux laptops
  • Android phones
  • iPhones

Therefore the router itself appears to be working normally.

Symptoms

The adapter:

  • Detects nearby networks correctly.
  • Shows strong signal levels.
  • Loads firmware correctly.
  • Creates wlan0 correctly.

Example:

nmcli device wifi list

Shows all nearby networks including my own network.

However, any connection attempt fails.

NetworkManager typically reports:

Activation: (wifi) association took too long
ssid-not-found

After a failed attempt, network scanning often becomes unstable and WiFi networks disappear until NetworkManager is restarted.

Restarting NetworkManager restores network visibility.

Router

Router: Totalplay ISP router.

SSID:

Totalplay-2.4G-bc38

Interesting observation:

The same SSID appears advertised through multiple BSSIDs:

64:9D:F3:1D:BC:38  Totalplay-2.4G-bc38
64:9D:F3:1D:BC:41  Totalplay-2.4G-bc38
64:9D:F3:1D:BC:40  Totalplay-5G-bc38

I disabled and reconfigured WiFi multiple times, including router factory reset.

The issue remains.

Driver messages

At boot:

b43-phy0: Broadcom 4322 WLAN found
Loading firmware version 784.2

At some point I observed:

b43-phy0 ERROR: Fatal DMA error
This device does not support DMA on your system.
It will now be switched to PIO.

Because of this, I currently use:

cat /etc/modprobe.d/b43.conf

options b43 pio=1

Current runtime value:

cat /sys/module/b43/parameters/pio

1

Direct wpa_supplicant test

To eliminate NetworkManager from the equation I stopped NetworkManager and tested directly with wpa_supplicant.

Configuration:

network={
    ssid="Totalplay-2.4G-bc38"
    psk=<generated_psk>
    bssid=64:9D:F3:1D:BC:38
    freq_list=2412
}

This forces:

  • 2.4 GHz
  • channel 1
  • BSSID 64:9D:F3:1D:BC:38
  • WPA2-PSK

Result:

Trying to authenticate with 64:9d:f3:1d:bc:38
freq=2412 MHz

nl80211: Authentication request sent successfully

Authentication timed out

The adapter sends authentication requests but never receives a response.

The failure happens before WPA key negotiation.

Additional observations

I tested:

  • Kernel 7.0.0-22-generic
  • Kernel 6.17.0-35-generic

Behavior changes slightly between kernels but neither kernel successfully connects.

I also created a fresh NetworkManager profile and forced:

key-mgmt=wpa-psk
proto=rsn
pairwise=ccmp
group=ccmp

No improvement.

Question

Has anyone seen BCM4322 + b43 authentication failures like this on recent Ubuntu kernels?

Could this be:

  • a known b43 regression?
  • a mac80211 regression?
  • a BCM4322 firmware issue?
  • an incompatibility with newer Totalplay access points?
  • a consequence of running the adapter in PIO mode after DMA errors?

Any suggestions for further debugging would be greatly appreciated.

journalctl shows almost nothing about Postfix [closed] https://askubuntu.com/questions/1567907/journalctl-shows-almost-nothing-about-postfix

I have some weird journalctl behavior.

I have two Ubuntu servers with postfix installed on them. If I run journalctl -f -u postfix@-.service on ServerA I got dynamically updated output, that shows me all postfix event: connetions, mail routing, putting messages to queue, etc. When I send some message via this server, corresponding events are shown in output almost immediately, but this not working on ServerB. On Server B it says fatal, the Postfix mail system is not running. If I run journalctl -f -u postfix@-.service I get output with a few old records and that's it, nothing else.

Why this happening like that? Is it journalctl malfunctioning, or postfix misconfigured?

This is screenshot from ServerA

This is screenshot from ServerB.

Problems with Ubuntu 26.04 unattended software update so as snap cannot install and update due to Intenet connection disconnected on raspberry pi 4 [closed] https://askubuntu.com/questions/1567903/problems-with-ubuntu-26-04-unattended-software-update-so-as-snap-cannot-install

Having lots of problems with Ubuntu 26.04 LTS and 26.10 that the wired internet connections always got disconnected. On raspberry pi 4.

The terrible is Ubuntu unattended software updates get so frustrating and annoying to use.

And lastly the snap also have a problems, cannot seems to update and install anything.

The fact of the problems is this is too way buggy and not functional to use on daily basis.

I wonder how to fix this problems.

Brave browser are flickering.

is there any commands to type on the terminals to troubleshoot the problems.

is there a way to disable the unattended updates, and the snap are not working well with updates. I had a very hard time to make it work. and it is very frustrating having an os that does not work.

so i try the daily build still the same thing nothing have change so far.

Ubuntu Kernel Panic - Please reboot your computer. VFS: Unable to mount root fs on unknown-block(0,0)(Linux 6.14.0-35-generic) [closed] https://askubuntu.com/questions/1567902/ubuntu-kernel-panic-please-reboot-your-computer-vfs-unable-to-mount-root-fs

Use Ubuntu 26.04 Live USB stuck on spinning circle (Try Ubuntu) on Intel Alder Lake N iGPU, works on 24.04.3 https://askubuntu.com/questions/1567901/use-ubuntu-26-04-live-usb-stuck-on-spinning-circle-try-ubuntu-on-intel-alder-l

I am experiencing a boot issue with Ubuntu 26.04 Live USB.

On the same hardware, Ubuntu 24.04.3 works normally and I can enter the "Try Ubuntu" desktop without any issues. However, Ubuntu 26.04 gets stuck at the spinning loading circle after selecting "Try Ubuntu" and never reaches the desktop.

Hardware:

  • CPU: Intel Alder Lake N (e.g. N97 / N305)
  • GPU: Integrated Intel iGPU (i915 driver)
  • Display: Tested with both HDMI and DP

Tested systems:

  • Ubuntu 24.04.3: Works normally
  • Ubuntu 26.04: Fails (stuck on loading spinner in Live session)

Observed behavior:

  • Spinning circle appears indefinitely
  • No desktop is reached

I also tried booting with "nomodeset", but the issue persists or only partially progresses.

This strongly suggests a regression in the graphics stack (kernel / i915 / mesa / GNOME shell) in Ubuntu 26.04 compared to 24.04.3 on Intel Alder Lake N hardware.

I would appreciate any guidance or workaround (kernel parameters or driver settings) to get Ubuntu 26.04 Live session working on this hardware.

Thank you.

Inkscape stopped working, assertion failed: display_wayland->cursor_theme_name https://askubuntu.com/questions/1567879/inkscape-stopped-working-assertion-failed-display-wayland-cursor-theme-name

I'm on Ubuntu 26.04 (was 25.10 at original time of writing) with default everything. Until I tried xfce (briefly) then switched back.

Since then I can't run Inkscape. When I run it from the terminal I get

$ inkscape

I think xfce might have reset the cursor theme, or I might even have done it myself, I don't recall.

But using Tweaks I've set the cursor theme to Yaru.

That theme isn't listed when I run

$ sudo update-alternatives --config x-cursor-theme
There are 7 choices for the alternative x-cursor-theme (providing /usr/share/icons/default/index.theme).

But /usr/share/icons/Yaru/cursor.theme does exist.

I have also tried running

$ dconf reset /org/gnome/desktop/interface/cursor-theme

and

$ gsettings reset org.gnome.desktop.interface cursor-theme

but no luck.

Following this question I checked and these files exist:

/usr/share/icons/Yaru/cursors/default
/usr/share/icons/Yaru/cursors/left_ptr

Any ideas what's wrong, and how I can get Inkscape running again?

Chrome slows then freezes https://askubuntu.com/questions/1567877/chrome-slows-then-freezes

After using for a period, Chrome sometimes becomes very slow and eventually freezes. Sometimes I can restart Chrome, other times I have to reboot my laptop. After many years of fault-free operation under Ubuntu, this problem has gradually become more frequent over the last few weeks.

Do you have any suggestions on how to find out what is causing the problem, and a possible cure? Please provide guidance on what diagnostic information would help to narrow down the cause.

System information:

  • Chrome Version 149.0.7827.155 (Official Build) (64-bit) - [latest stable version of Google Chrome for Linux on 22-Jun-2026]
  • Ubuntu 24.04.4.LTS
  • Laptop: Dell Inspiron 13 7000

Diagnostic Information:

  • System Monitor shows multiple errors even before slowdown, mostly of the form '/opt/google/chrome/chrome -type-renderer --crashpad-handler-pid-4808-enable-crash-reporter-.... followed by another 10 lines of alpha-numeric words and numbers. (I'm not sure if this is connected to the slowdown/freeze problem, although I did once notice a big increase in the number of processes of this type, although I did not manage to capture the details).

  • CPU usage has periods of 100% usage on some of the 8 CPUs

  • System Memory (8.0 GB) was 100% full just before latest crash.

  • After restart, System Memory started at 20% with single tab on Chrome, increased to c. 40% with 6 tabs. swap is at <10%

  • 2-3 hours after restart with 2 Chrome windows, email, LibreOffice Writer, etc. running, memory and swap usage are both >80%

How to show seconds by hovering on the clock in Ubuntu? https://askubuntu.com/questions/1567866/how-to-show-seconds-by-hovering-on-the-clock-in-ubuntu

I was using Kubuntu, but the new LTS slowed my computer down so I'm back to an older Ubuntu LTS. I'd like to see the seconds but the same way I was able to do it in Kubuntu, by hovering over the clock, not showing them all the time on the regular clock (because that's supposed to use more computing power) so, does anyone know how to do it? Or at least showing them in the dropdown calendar instead of the top bar?

GNOME Panel & Activities Overview workspace thumbnails flickering issue https://askubuntu.com/questions/1567665/gnome-panel-activities-overview-workspace-thumbnails-flickering-issue

GNOME Activities Overview workspace thumbnails begin flickering after about 10 minutes of uptime on Ubuntu 26.04 LTS with GNOME Shell 50.1 running on Wayland and Intel Alder Lake-N integrated graphics (i915 driver).

System:

  • Ubuntu 26.04 (upgraded from 24.04)
  • GNOME Shell 50.1 / Mutter 50.1
  • Wayland session (no Xorg session available)
  • Intel Alder Lake-N UHD Graphics (i915 driver)
  • Three displays (all 1920×1080 @ 60Hz)

Symptoms:

  • After about 10 minutes of uptime, GNOME Activities Overview becomes visually corrupted.
  • Specifically, workspace thumbnails flicker immediately upon entering Overview (Super key or hot corner).
  • The flickering is limited to Overview workspace thumbnails and GNOME top bar. Normal desktop, application windows remain stable and unaffected.
  • Exiting Overview immediately returns the desktop to normal. Logging out and back in resolves the issue temporarily, but it returns in a few minutes, rebooting it returns after 10 or 15 minutes. No GPU resets, hangs, or DRM errors appear in journalctl.

I’ve tried:

  • Kernel parameter: intel_idle.max_cstate=1 Appears to delay or partially change the symptoms, but the issue still occurs.
  • Kernel parameter: i915.enable_dc=0 Initially seemed to reduce symptoms, but the issue still returned.
  • Tested different kernels (including older kernel) No change in long-term behavior.
  • Disabled a couple of third-party GNOME extensions (still using default Ubuntu extensions).

Observations:

  • The issue does not affect application rendering or the desktop outside of Activities Overview.
  • It appears only after extended uptime (hours), not immediately after login. - Update - this occurs sporadically, sometimes 10 minutes and some boots it would take a few hours.
  • The issue is reproducible across reboots and kernel versions.
  • No relevant errors in journalctl related to i915, DRM, or GPU resets.

Question:

Has anyone seen GNOME Activities Overview workspace thumbnail flickering or corruption on GNOME Shell 50 / Mutter 50 under Wayland, particularly on Intel integrated graphics? Are there known issues, workarounds, or logs that I should investigate further?


Update:

I performed additional testing and found a significant correlation with monitor configuration.

With my original multi-monitor setup (2 ASUS monitors + 1 TCL TV), GNOME Shell produced thousands of repeated errors:

gbm_surface_lock_front_buffer failed Failed to query buffer age, got error 3003

These sessions also exhibited Activities Overview flickering, top-panel flickering, and occasional window-edge artifacts.

I have now tested the system with a single display only (different display: Sony TV over HDMI) and the issue has not reproduced. There is no visible flickering, no rendering corruption, and:

journalctl -b | grep -c "gbm_surface_lock_front_buffer failed" 0

journalctl -b | grep -c "Failed to query buffer age" 0

The issue also reproduced across multiple kernels, including a newer mainline kernel Linux 7.0.12-070012-generic, which makes a pure kernel/i915 explanation seem less likely. Using this mainline kernel the symptoms also started appearing after roughly 10 minutes rather than a few hours.

At this point, the strongest lead appears to be a GNOME Shell/Mutter multi-monitor rendering issue, or an interaction involving multiple outputs.


Update (June 22nd):

The issue now consistently appears ~10 minutes after boot (earlier testing likely just didn’t run under full load).

The “unplug/replug” suggestion didn’t help, but it led to a reliable workaround: boot with only the DP 4K display connected, wait a few minutes, then connect the first HDMI display, wait again, then connect the second HDMI display. This results in a stable session and has provided ~20 hours of uptime without flickering or GBM errors.

I’ve reverted all system tweaks and returned displays to:

DP-1: 3840×2160 @ 60Hz, 200% scaling HDMI-1: 3840×2160 @ 60Hz, 200% scaling HDMI-2: 1920×1080 @ 60Hz, 100% scaling

(Previous all at 1080p configuration was part of testing.)

Driver and desktop tests:

Tried Intel Xe driver → same issue Tried KDE Plasma and Budgie → no flickering/GBM errors, but DP 4K display stayed black until forcing 30Hz via CLI (GUI wouldn’t allow it), so I reverted back to GNOME

Current conclusion: GNOME + Intel display stack on this hardware appears unstable only in full 3-display configurations. Any 1–2 display combination is stable for long periods, but stability on 3 displays only occurs with the staged hotplug sequence (DP first, then HDMIs). Adding DP last reliably triggers the issue.

At this point, this is a workaround rather than a fix.

Camera not working - ubuntu 26 https://askubuntu.com/questions/1567617/camera-not-working-ubuntu-26

I have a Lenovo ThinkPad X9-15 Gen 1 with Ubuntu 26.04 (Resolute Raccoon, kernel 7.0.0-22-generic) and the built-in camera is not working in any application (Firefox, GNOME Camera, etc.). I tried to replicate solutions, given for ubuntu 24, but with no avail.

Some troubleshooting

Ubuntu version: 26.04

Ubuntu sees the camera:

$ v4l2-ctl --list-devices
Intel MIPI Camera (platform:v4l2loopback-000):
    /dev/video0

What I've already tried:

  • Installed oem-sutton-dana-meta, libcamhal0, linux-modules-ipu7-generic, v4l2loopback-dkms

  • v4l2-ctl --list-devices shows the camera via v4l2loopback

  • ipu7x.so is present in /usr/lib/libcamhal/plugins/

  • pw-cli list-objects shows the camera in PipeWire

v4l2-relayd -d fails with:

CamHAL[ERR] load_camera_hal_library, failed to open PCI device
gst_parse_launch_full: assertion 'pipeline_description != NULL' failed

libcamhal-ipu7x cannot be installed due to broken dependencies:

Depends: libjsoncpp25 but it is not installable (Ubuntu 26.04 has libjsoncpp26)
Depends: libia-cca-ipu7x0
Depends: libia-log-ipu7x0

Does anyone know what the problem is?

Is there a way to install Ubuntu on a manually created luks-encrypted LVM? https://askubuntu.com/questions/1566492/is-there-a-way-to-install-ubuntu-on-a-manually-created-luks-encrypted-lvm

I have a test system with two physical disks. I'm trying to recreate a setup I used to use years ago where I could span volumes across said physical disks. I never considered it a complicated setup but, I can't seem to duplicate it with ubiquity. When I did this last, the installer was still text based and that doesn't seem to be an option these days. I attempted the following within the Ubuntu 26.04 Live environment.

My two physical drives, in this example, are /dev/sda & /dev/sdb. I went looking for the equivalent commands and I think I got close. What I did is below:

  1. I created partitions for the EFI boot stuff and LVM: sudo fdisk /dev/sda

    1. Made one primary partition, about 1GB

      1. Flagged it ef for EFI (/dev/sda1)
    2. Made a logical/extended partition for the rest of the drive

      1. Flagged it 8e for Linux LVM (/dev/sda2)
  2. I created created one logical/extended on the second drive: sudo fdisk /dev/sdb

    1. Flagged it 8e for Linux LVM (/dev/sdb1).
  3. I then used LUKS to encrypt the partitions that will be used for the system:

    1. sudo cryptsetup open /dev/sda2 crypt_drive1 && sudo cryptsetup open /dev/sdb1 crypt_drive2
  4. I then opened those encrypted partitions:

    1. sudo cryptsetup open /dev/sda2 crypt_drive1 && sudo cryptsetup open /dev/sdb1 crypt_drive2
  5. I then set up a volume group with some logical volumes:

    1. sudo pvcreate /dev/mapper/crypt_drive1 /dev/mapper/crypt_drive2

    2. sudo vgcreate vg_system /dev/mapper/crypt_drive1 /dev/mapper/crypt_drive2

    3. sudo lvcreate -L 8G -n lv_swap vg_system

    4. sudo lvcreate -l 100%FREE -n lv_root vg_system

At this point, I figured I was good to go so I fired up the installer wizard and tried to run through the installer. When I got to the partition setup, I selected the option for a manual setup and expected to see my logical volumes available but didn't. I was able to select /dev/sda as my boot device and it set dev/sda1 as the boot partition but, it's not showing the logical volume stuff. Below, is a screenshot of where I'm stuck. I'm sure I missed a step. Where did I go wrong?

Wi-Fi randomly stops working on Dell G15 (Intel iwlwifi, Ubuntu 22.04) https://askubuntu.com/questions/1561873/wi-fi-randomly-stops-working-on-dell-g15-intel-iwlwifi-ubuntu-22-04

The Problem

Wi-Fi works when it wishes to. Sometimes it works fine with heavy downloads and fast speed. Sometimes goes on strike. It decides to stop working soon after boot, after many minutes, or hours, or not at all.

Symptoms

On the widget on the top right the wifi cannot detect networks, and if wifi is turned off it cannot turn on. Sometimes on boot the wifi voice on the drop-down menu is not even showing. lshw -c network shows network UNCLAIMED.

Latest diagnostics (23/06/2026)

What I tried

I've tried reinstalling linux-firmware, NetworkManager restarts, to no avail. After a while, something randomly breaks, and it is especially frustrating as I have no easy access to ethernet cables.
Using older kernels did not work either.
I found that, SOMETIMES, flea reset OR messing with unimportant BIOS options, booting the os, rebooting and changing BIOS options again sometimes allows me for sustained network access (a suggestion I found browsing for solutions)... maybe this last one is not effective, I don't know how to check.

Technical Information

Hardware information

I own a gaming Dell G15, with Ubuntu22.04.1 preinstalled. No dual boot. Has worked perfectly for more than 1 year, even after I upgraded it to 24 (now it is back to 22, after factory reset). I use it for everything: work, scientific computation, watching videos, and gaming.

Secure boot is turned off. The original kernel for this Dell was an oem kernel listed as 6.1.0-1013.13_oem. I have installed HWE kernels and I am currently running the latest hwe for ubuntu22.04.1.

This is some of the output from neofetch and nvidia-smi:
OS: Ubuntu 22.04.5 LTS x86_64
Host: Dell G15 5530
Kernel: 6.8.0-124-generic ~previous: 6.8.0-90-generic ~ CPU: 13th Gen Intel i5-13450HX (16)
GPU: NVIDIA GeForce RTX 3050

Final notes

I welcome any advice on what to do when it will break, or why does it do that, additional diagnostics, readings, tools to install, etc. are more than welcome. E.g. I have just installed net-tools and iw, and I have read conflicting and old advice suggesting to install backport-iwlwifi-dkms.

Also, the guide in https://help.ubuntu.com/community/WifiDocs/WirelessTroubleShootingGuide seems to be somewhat helpful with understanding the diagnostics. Sadly, it does not provide any help when dealing with the problem I am experiencing.

edit 24/12/2025

The problem manifested again. All I did was

  • deactivated airplane mode
  • connecting to my cellphone hotspot
  • updating snap
  • sudo apt update
  • check what was to be updated (google chrome, libre office, vscode)
  • sudo apt upgrade
    I lost wifi at 20% of the chrome download.
    After the reboot I resumed the upgrade, and it blocked at 60%, then 98%. After that the wifi disappeared altogether.
    What I tried and did not work:
  • rebooting;
  • using different kernel versions;
  • Changing BIOS options;
  • nmcli networking off && nmcli networking on;
  • nmcli radio wifi off && nmcli radio wifi on.

What did work for a bit:

  • flea reset. The diagnostics were updated in this edit. This is the old diagnostic of the wifi when it is not working: https://paste.ubuntu.com/p/xnYs8dGp5W/
    I am keeping it for reference, but it lacks iw outputs.

edit 23/06/2026

After a firmware update for this machine, Dell G15, the problem did not present itself for months. With the last update things went back to the usual problem. The diagnostics were updated in this edit.

Additional workarounds I tried that failed were:

  • sudo iwconfig wlp0s20f3 power off and sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf and reboot, as suggested by @Jeremy31
  • added options iwlwifi 11n_disable=1 in /etc/modprobe.d/iwlwifi.conf as explained in What is "options iwlwifi 11n_disable=1" in WiFi setting?

I noticed that many error logs show "microcode" sudo dmesg | grep -iE 'microcode' [ 1.111249] microcode: Current revision: 0x00000133 [ 391.120843] iwlwifi 0000:00:14.3: Microcode SW error detected.

Ubuntu 22.04 XRDP Allow multiple sessions and restrict some users https://askubuntu.com/questions/1433247/ubuntu-22-04-xrdp-allow-multiple-sessions-and-restrict-some-users

I have installed xrdp on Ubuntu 22.04 Server where I also installed ubuntu-desktop for development and testing. When one user is logged in through remote desktop, others cannot login. How to allow multiple logins (different users)?

Also, how to allow some users to login using xrdp and disable xrdp login for other users? I have four users. I want to allow accesses for two and disable access for the other two.

For ssh, it can be done using DenyUsers as answered here. Does something similar exists for xrdp?

There is one accepted answer here but I couldn't make it work.

How to install a newer/different libc6 version? https://askubuntu.com/questions/1389796/how-to-install-a-newer-different-libc6-version

I'm using Ubuntu 20.04 focal fossa.

I'm trying to install a package that depends on libc6=<2.33 or above. However, focal repositories only have version 2.31, which is causing dependency troubles:

Depends: libc6 (>= 2.34) but 2.31-0ubuntu9.2 is to be installed

Is there any way I can install libc6 2.34 or above on Ubuntu 20.04 focal?

$ apt-cache policy libc6
  Installed: 2.31-0ubuntu9.2
  Candidate: 2.31-0ubuntu9.2

Unable to Select an UEFI file as trusted for executing - no drives shown https://askubuntu.com/questions/1002187/unable-to-select-an-uefi-file-as-trusted-for-executing-no-drives-shown

After installing Lubuntu, I got the No bootable device error, and after searching the net for a solution, tried to set the Select an UEFI file as trusted for executing option as instructed, but it does not show me any drives. The Information screen in the bios setup shows me HDD0, but the Security screen that's supposed to let me select the efi file shows nothing, unless I insert the USB. I set the supervisor password after installation, and I thought this may be a reason, and installed it all over again. But it's still showing me nothing. I am sure the installation was done on the hard disk because all previous boot options are gone (as I wanted).

What can be the problem? P.S. I am new to Linux.

Edit:

I have tried turning off secure boot, but it did not help.

I have checked and there is one partition with file system lvm2 pv with flags boot and lvm.

It's an Acer Aspire E 15 (E5-575-50RM) that came with Linpus and had no GUI. I have installed lubuntu-17.10.1-desktop-amd64.

I did not use any software to create the USB since my Windows XP is damaged and files are missing or corrupted. I used EaseUS Partition Master to format the USB as FAT32 and then copied the extracted ISO files to it, then marked the single partition as active.

"(CRON) info (No MTA installed, discarding output)" error in the syslog https://askubuntu.com/questions/222512/cron-info-no-mta-installed-discarding-output-error-in-the-syslog

I have a fresh install of Ubuntu 12.04.1 LTS an a number of servers.

I have not added any cron jobs or edited my crontab on those servers, however, at around the same time for each machine, I get a 75% CPU spike and the following info in my syslog at the time of the spike:

CRON[8380]: (CRON) info (No MTA installed, discarding output)

I have mono-complete installed and am running a service stack webserver.

What is the best way for me to stop this from happening? I would like to be able to remove the CPU spike.
