After a few updates last week my pc wont shutdown. just stays on a black screen but hardware is on. I can dual boot to win10 and it shutdown or restarts just fine. Also, my wife has same exact hardware and software and she doesn't have same problem. Her PC reboots flawlessly.
I was using my Ubuntu normally, and then after a reboot I can't unlock my LUKS container. I've already tried dozens of passwords whether I forgot or have gone crazy, but nothing worked. On cryptsetup it appears to be healthy and normal. Unfortunately I don't have backups.
How do I connect my Ubuntu computers using a wifi router?
I am a very recent convert to Ubuntu, as in just this weekend. I put together a new computer, and decided to make the jump from Windows 10 to Ubuntu. I've been trying to search for answers as I can and make it work, but I'm having some trouble with this one.
I've got a fresh install of Ubuntu 26.04. As a practice with previous computers, I put the OS on a small dedicated SSD and use a larger SSD for apps and general storage.
I've tried following a few guides on how to mount an additional drive and have the OS automatically mount the drive on startup, but I've been unsuccessful so far.
I have successfully formatted and partitioned the 2nd drive as vfat using GParted, and added a line to /etc/fstab for the new drive as instructed by an instructional here. The issue could be that the instructional is 14 years old, and the method has changed since then. Any help is appreciated.
After upgrading to 26.04 LTS, i have faced issues when switching workspaces using a touchpad gesture. Desktop folders are hidden and drag selection also disappears
I am running Ubuntu 24.04 LTS (Noble Numbat) and keeping getting a GPG signature verification error whenever I run sudo apt update.Here is the exact terminal output log:

What I have tried so far:
1 .Manually downloading and piping the key with wget and gpg --dearmor into /etc/apt/trusted.gpg.d/ and /etc/apt/keyrings/. wget repeatedly fails with no valid openPGP data found or throws a parsing mismatch.
2 . Fetching via keyserver directly using gpg --keyserver keyserver.ubuntu.com --recv-keys 32EE5355A6BC6E42. This continuously results in a gpg: could not parse keyserver URL error.
3.Running apt-key adv --keyserver hkp://://ubuntu.com --recv-keys 32EE5355A6BC6E42, but the terminal throws a no such file or directory or layout execution block.Since the repo file is automatically re-configured by Google's background cron script, adding a local signed-by tag directly to the .list file gets overwritten.
How can I get Ubuntu 24.04 to properly ingest and retain this Google Earth public key globally?
Issue: VLC freezes Ubuntu 26.04 LTS OS while playing large playlist set to random daily. Mouse is unresponsive and have to press CTRL+ALT+DEL, sign out, sign in, and relaunch playlist to correct.
This is a PC being used in a video art installation in a gallery. It's a bit of a drive and I have to pay for parking each time I work on the PC as it is live in the gallery exhibition presently when we discovered the issue. The staff are kindly signing out and back in and relaunching it each time it freezes but they need me to fix it ASAP.
System Specs:
The video content comprises old 80s cartoons and Saturday morning commercials which display on the CRT. The files are modest in size and low to medium resolution but it is a very large playlist, (about 60 days of continuous content). No HD content. VLC is set to play the playlist with random mode enabled. I also set it to expand all subfolders by default for the playlist.
The PC was freshly formatted with a bootable Ubuntu flash drive and the latest stable OS version installed.
All of the media content was transferred using FreeFileSync to verify data integrity to a folder on the PCs desktop. A playlist was generated of the folder's content which is what we launch in VLC each exhibition day.
The playlist runs day and night and we power off the CRT after hours to preserve its life. There is a small standard monitor connected which is set to mirror to the CRT.
I configured VLC to ignore all non-video file formats so that miscellaneous content from the folder wouldn't present an issue when I generated the playlist.
No other applications were installed and no other changes were made to the freshly-formatted PC other than the aforementioned media folder.
I read that VLC doesn't generate a log file by default. I've tried to provide all available information to expedite a resolution.

I searched the Ubuntu section of the VLC support forum for "freeze" and couldn't find a solution.
I posted the above to the VLC forum and the reply I received stated: "VLC can't freeze the whole OS, only itself. Looks like your display server is what is crashing. Update it or use another one."
I believe I'm running Wayland (the default), and I stated that I performed a fresh install of the latest stable version of Ubuntu so I would be inclined to think that I'm already using the latest version of the best display server.
I hope to not have to migrate the playlist to another video application as I mentioned I already configured VLC to ignore a whole list of non-video file types which occupy the collection folder/subfolders. And I am fairly competent with VLC vs learning an entire new application for the art exhibit which may introduce new issues. Staying with VLC is ideal.
I'm posting to the Ubuntu support forum as the VLC community said VLC can't freeze the OS so it's likely a video server issue. Can someone provide specific steps for me to resolve the freezing issue?
Thanks for any help you can provide!
Recently, on this Dell Latitude 7380, running Ubuntu 24.04.4 LTS with Wayland, the kernel updated from v. 6.17.0-40-generic to 7.0.0-28-generic. After rebooting the display became extremely dark, starting immediately after the selection of OS was made in grub. It was barely readable in a dimly lit room, and it also appeared to flicker slightly.
Rebooting and selecting kernel 6.17.0-40 from grub worked normally, with fully controllable brightness. Retesting both kernels gave consistent results. For now, I've changed the grub selection order so that 6.17.0-40 is the first, i.e., default entry. That kernel and its header also have been set on hold. However, I'd like to know what causes the issue, and if there is a workaround, or newer kernel in the pipeline that could be tested to see if the issue has been resolved.
The results of uname -a are as follows for the new and old kernels, respectively:
Linux <PC_NAME> 7.0.0-28-generic #28~24.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Jul 1 15:50:57 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Ubuntu 24.04 up to date
Gthumb 3.12.10
All of gThumb's functions work properly except for printing.
It was printing a while back. I don't know how long ago, but it was not long, a few weeks maybe. I updated the system as usual, 1 or 2 times. Now Gthumb crashes when I try to print a jpg. It never has before.
I uninstalled it, reinstalled it and did the same with the printer, a Brother MFC-2710DW. The printer works as expected from other apps, including GNome Image Viewer 45.3.
This is different from How to install software or upgrade from an old unsupported release? since I have already changed my repos to old-releases.ubuntu.com and done everything else from that issue.
Here is the ultimate failure (all the prep-work is below). Note: I mangled the protocol on the URLS to bypass the spam detector (http:// --> http-)

Any thoughts?
OSK keeps popping up in clamshell mode on my Dell 2-in-1 laptop. So then I do Settings > Accessibility > Typing > Screen Keyboard > toggle off, and that persists across that session and even a restart, but the next day, the setting has flipped back to on! Block Caribou didn't work for me. This issue happens when I'm in clamshell mode and clicking into text boxes in certain apps, such as Terminal, Files, Settings, or Thunderbird, but not Bitwarden or VSCode. It also happens on the login screen.
Some commands I've ran:
Could someone please help me disable the OSK until I want to use it? Thanks so much!
I was installing Ubuntu Desktop 26.04 onto my drive when an error came up saying something went wrong but it didn't know what. The logs showed errors like grub-install: warning: efivarfs_set_variable: writing to fd 9 failed: Cannot allocate memory.
My laptop is an Asus x1404za with 8GB of RAM, 128 GB of storage, and a 12th gen Intel Core i3. I've added an ax210 to it for my previous Linux installation.
I believe I have done everything right, although I am new to Linux.

I frequently experience hotspot and ethernet connection problems on my Ubuntu OS, sometimes, it connects successfully but I can not access anything on the internet whiles at the same time, with the same hotspot, I can connect with my Windows OS and it works. I am using Ubuntu version 26.04.
I have a small server (Zotac ZBOX-AD06-U) running Ubuntu 24.04. Twice now it's had an entire series of corrupted files on the HDD. (This time it's affected apt such that apt --fix-broken install fails; I think a reinstall will be required regardless.) It'll hang at boot complaining that a manual fsck is needed, then give errors like "inode <inode id> seems to contain garbage". The SMART diagnostics aren't finding anything wrong.
How can I tell if there's a hard drive problem doing this? What other troubleshooting can I do to try to narrow it down?
What can I do to prevent it in the future?
SMART data is below. The short and long tests at 156xx hours was after this event, and I believe the two tests at the 86xx mark were last time this happened. (No telling how long it had inode errors between these two. It is very rarely rebooted.)

I'm running a Dell Optiplex with integrated intel video card. I recently upgraded from a live USB, wiping the root directory, but kept my home directory in place.
Since upgrading to 26.04, I can hear my fan rev up any time my browser tries to load a page with a lot of images. Like Amazon or Ebay, where there's an array of images on a page. I don't know if it's this or the Javascript, but it takes a long time to load and I can hear the fan always revving up.
Mouse performance becomes choppy over time. I'm running dual monitors, the first with Displayport and second with HDMI and when I move the cursor from the first to the second, I can see it stutter.
In general, I'm just getting laggy performance and it feels like a video card-related issue. Has anyone been having these problems, and how do you fix them?
I'm upgrading from the last LTS release (24.04). Prior kernel was 6.17 and the new one is 7.0.0. Graphics specs are below:

I am getting the apparently common problem of a boot partition with 0 space left. I have gone through the best links that I found so far, but with no luck resolving it (partly because I'm a noob).
How do I free up more space in /boot?
The autoremove command does not work because it needs to create files, but there is no space left to do so.
The sudo apt-get purge command also fails due to an attempt to create files again was met with no space left.
The boot partition is 2GB and attempting to expand partition doesn't work (using Disk Utility) because there is no non-filesystem free space left on the 2TB drive.
EDIT:
Below is contents of the /boot folder, then the result of df -h. I am on "Ubuntu 26.04 LTS - Framework desktop". Is it safe to manually delete files listed as 7.0.0-15 (old kernels?) via sudo rm instead of purge which does not work (requires space)

After a routine fwupd firmware update my laptop's built-in screen became very dim, even at "100%" brightness. An external monitor on the same machine looks completely normal.
Laptop: Dell Latitude 5430, Intel Iris Xe (Alder Lake, i915), internal eDP panel (AU Optronics).
OS: Ubuntu 24.04, GNOME.
Trigger: fwupd auto-flashed the Dell system BIOS from 1.36.0 to 1.39.1 (check with fwupdmgr get-history). The screen was fine before that.
What I already ruled out (none of these help):
Not a kernel regression — dim on every kernel I tried; the panel is only bright in recovery mode / with nomodeset (i.e. when i915 is not driving it).
Not gamma/ICC — xrandr Brightness 1.0, Gamma 1.0, no VCGT in the ICC profile.
Not a software brightness slider — /sys/class/backlight/intel_backlight reports brightness == actual_brightness == max_brightness (1023), yet the panel is dim.
Brightness keys only make it dimmer, never brighter.
Downgrading the BIOS is blocked: LVFS only offers 1.39.1, so fwupdmgr / GNOME Firmware cannot roll back.
How do I get the panel bright again without a BIOS downgrade?
Chromebook in question: HP Chromebook x2 - touchscreen tablet with detachable keyboard.
Following the guides on mrchromebox.tech, I was able to get Lubuntu installed. Everything is working great except the trackpad. The cursor "warps" to the corresponding location on the screen to wherever I touch the touchpad (if I touch the top left of the touchpad the cursor instantly moves to the top left of the screen) and it constantly clicks and drags as I move my finger around the touchpad.
Touchpad in question:
I haven't used Linux in a decade or so so you'll have to excuse my ignorance. I used AI to give some bash commands for the below info. Let me know if I can provide more info.

System info:
I’m having a Wi-Fi issue on my ASUS Vivobook (X1504ZA) running Ubuntu 26.04 LTS. I don’t really know much about this kind of Linux/driver/network stuff, so I’ve been trying to figure it out step by step.
My Wi-Fi card shows up as:
MediaTek MT7902 802.11ax (Filogic 310)
PCI ID: 14c3:7902
Internet works fine using USB tethering from my phone
System is updated (kernel: 7.0.0-22-generic)
Everything else on the system seems normal
No Wi-Fi option appears in network settings
nmcli shows no Wi-Fi device at all
The Wi-Fi hardware is detected by the system but marked as UNCLAIMED
The mt7921e driver loads, but it does not attach to this device
I honestly don’t know much about drivers or kernel stuff, so I used an AI assistant to help me troubleshoot step by step. We checked logs, drivers, and kernel modules together.
From what we found:
The Linux mt76 / mt792x drivers are installed
But they don’t seem to support my exact chip (14c3:7902)
So the system detects the hardware, but no driver actually connects to it
It looks like the Wi-Fi chip is not supported (or not fully supported yet) in my current Linux setup.
I’m currently just using USB tethering from my phone, which works fine for internet.
Since I don’t really understand this technical stuff deeply, I thought I’d ask here in case someone knows a fix, patch, or workaround for this specific Wi-Fi chip.
Any help would be really appreciated 🙏 Should i install windows now?
I installed Ubuntu 24.04 on my Asus Vivobook M1502YA (Ryzen 7 7000 series), but the Wi-Fi doesn’t work at all.
Details:
Wi-Fi chip: MediaTek MT7902 (lspci shows 01:00.0 Network controller: MEDIATEK Corp. Device 7902)
Kernel: 6.17.0-20-generic (uname -r)
What I tried:
Upgraded to latest kernel using Mainline
Installed linux-firmware
Ran sudo ubuntu-drivers autoinstall
Checked rfkill (no soft/hard block)
Output:
ip a
# shows only:
1: lo: <LOOPBACK,UP,LOWER_UP> ...
2: enx... (USB tethering interface)
# No wlan0 or wlp interface detected
Problem:
Wi-Fi interface is not detected. USB tethering works, so internet is fine.
Question:
Is MediaTek MT7902 supported on Ubuntu yet?
Any workarounds or experimental drivers to get it working?
Thanks in advance!
I have a new ASUS Vivobook X1404ZA laptop. I installed Ubuntu, but the Wi-Fi and Bluetooth are not working. The Wi-Fi icon doesn't show any networks, and Bluetooth seems to be missing. Here is my technical information: --- **
1. My Wi-Fi/Network Controller:** (Output of `lspci -nn | grep -i network`)
03:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7902]
---
**2. My Kernel Version:**
6.17.7-061707-generic
---
**3. My Kernel Log (dmesg):**
(Output of `sudo dmesg | grep -iE 'mt79|7902'`)
[ 0.276113] pci 0000:03:00.0: [14c3:7902] type 00 class 0x028000 PCIe Endpoint
[ 221.622095] mt7921e: unknown parameter 'disable_usb_sg' ignored
*(Note: My `dmesg` also shows many `mt7921e` errors, but this seems to be the wrong driver for my [14c3:7902] hardware).*
---
**4. RFKill Status:**
(Output of `rfkill list`)
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
*(As you can see, `rfkill` only detects Bluetooth, not the Wi-Fi device, confirming the kernel is not loading the Wi-Fi driver).*
---
What is the correct driver for the MediaTek MT7902? I tried loading `mt7925e` but it didn't seem to work. How can I get this hardware enabled?
Thank you.
In short: how I can I use the Plasma desktop environment over VNC?
I am running Ubuntu 22.04.3 LTS with KDE Plasma 5.24.7 (the "Kubuntu" image install).
Logging in to the machine physically is fine and the UI looks awesome. Now I want to access the machine using something like remote desktop, I figured VNC is the best option.
So I install and run tightvncserver on the machine, basically following this guide:
sudo apt install tightvncserver
tightvncserver :1
I can already remote in now, from Windows, using the RealVNC client. However, the screen is just empty.
So I go back to my machine to change ~/.vnc/xstartup and make it look like:
#!/bin/bash
xrdb $HOME/.Xresources
startxfce4 &
After restarting the VNC server I can now remote in and actually see and use a desktop, but the environment is of course now Xfce, instead of KDE Plasma like I use with physical access.
How can I use KDE when using VNC? Which xstartup command would I need?
I have already tried startkde &, startx & and startplasma-x11 & but all of those just result in a plain grey screen.
Specifically I found this guide which suggests the following for xstartup:
#!/bin/sh
# Start up the standard system desktop
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
/usr/bin/cinnamon-session
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
x-window-manager &
Now I get the Plasma loading splash screen on VNC connect, but after a few seconds the screen becomes black. The full error log for this from TightVNC:

Similar questions that are close but of no help to me:
I am using Ubuntu 20.04 with kde plasma. All of a sudden, my Dolphin file browser takes forever to open. Earlier it opened instantly, but now it is taking almost 30 seconds to start.
This seems to have started after an update; when I use kernel 5.11.0-38-generic there is no issue: the problem occurs when I use kernel 5.11.0-41-generic. In addition when on 5.41 the whole system seems to run slower.
When I run dolphin from the command line, there is no error output, and it is as slow as before to open.
I am using an Intel 4690k CPU with 16GB ram and SSD. I checked my drive health and it is fine.
After doing the upgrade to Xubuntu 20.04.2 LTS from Xubuntu 18.04.5 LTS on my HP Elitebook 820 G1 I've had an issue with my screen going blank at random. I can't see anything interesting in journalctl or dmesg.
The only way I've found to wake up the screen is to close and open the laptop lid.
I've tried changing the power management settings, but it doesn't help.
I'm starting to suspect that this is an issue with the new display driver not being fully compatible with my computer.
A solution might be to downgrade the display driver to the version used in Xubuntu 18.04.5 LTS?
Would be happy for suggestions for a solution for this problem!
This command wakes the screen again:
xrandr --output eDP-1 --off && xrandr --output eDP-1 --auto
A better workaround is to program the power button as "hibernate" and push it to hibernate and then again to wake up. This resets the screen and has the pro of not messing up what's on what screen which happens when I run the above command.
Whenever I boot up, my monitor's settings are always zoomed in about at 10, out of a scale of 0-100.
It also happens if I turn my monitor off and on again.
If I change my Display settings to rotate my screen orientation from Landscape to Portrait and back, but not Landscape to Flipped Landscape and back.
And changing the Scale in the Display Settings menu doesn't mess up the Zoom again, either.
I have a Dell SP2208WFP, and my Monitors.xml looks like:
<monitors version="2">
<configuration>
<logicalmonitor>
<x>0</x>
<y>0</y>
<scale>0</scale>
<primary>yes</primary>
<monitor>
<monitorspec>
<connector>HDMI-A-1</connector>
<vendor>DEL</vendor>
<product>SP2208WFP</product>
<serial>RR268831CT0U</serial>
</monitorspec>
<mode>
<width>1680</width>
<height>1050</height>
<rate>59.954250335693359</rate>
</mode>
</monitor>
</logicalmonitor>
</configuration>
</monitors>
...
And now, Scale is reset to 1... Because I exited a fullscreen app or something?? Scale doesn't seem to affect the actual monitor, anyways. I change it with Display Settings to 125%, and it changes to 1.25 in monitor.xml, but nothing changes to the monitor itself.
...
It even happens in Recovery Mode, when I don't have a DISPLAY variable set.
...
But, it doesn't seem to happen if I connect through VGA instead of HDMI...
Still happens in 26.04 Ubuntu Desktop, Doesn't happen on my Windows 10 machine, and zoom level changes accordingly when I between them using a UGreen HDMI splitter (ACBUGN50966).
Doesn't happen on a boot, until after the spinny icon / booting screen refreshes. Not sure what the refreshing indicates, but something?
I am currently using Ubuntu 19.10 with the unity DE and I always use mpv to play videos in Ubuntu. As mpv has few GUI options, there is no GUI option to rotate a video, but we can rotate it with the help of the command line. For example, we can rotate a video by 90 degrees using the command below:
mpv --video-rotate=90 /home/guest/new_vdo.mp4
This way (using the terminal) however, I have to type the command every time I want to rotate the video.
How can we create a keyboard shortcut to rotate a video which is currently playing in mpv?
I've encountered a problem while I was trying to set an encrypted logical partition for personal data. All I did was formating some free space on the same hard disk I installed Kubuntu using the KDE Partition Manager. I read multiples guides online on how to decrypt and use the encrypted partition and pretty much everyone suggests to use the cryptsetup command, then mount the partition somewhere in / and it should be ready to use. The problem is that whenever I launch the cryptsetup command, I receive the following error:
Cannot use device /dev/sda5 which is in use (already mapped or mounted)
Here is the command I launched:
sudo cryptsetup open /dev/sda5 partition-enc --type=luks
A not really elegant workaround seemed to be "deactivate" the logical partition in the KDE Partition Manager to make the cryptsetup command execute without errors, however, even doing so, the mounting process will give a unknown filesystem type 'crypto_LUKS', which means the file system has not been decrypted successfully, I reckon.
Disclaimer: I already searched for similar questions and issues online of course, but no one seems to be solved. I don't know if I'm doing something wrong but no guides or discussion I found seems to take this problem into account.
I just installed Ubuntu on a new machine and everything seemed to be going fine. I and a coworker were having some issues with a few things and have managed to lock-out a local admin (sudo?) account after unjoining an AD domain using realm while troubleshooting some McAfee issues were were having. I'm 99.9% certain that the password has not changed for the user. I have followed ALL the steps found here for resetting the password as root in recovery. When I try to run
sudo passwd USERNAME
I get the error:
root@hostname:~# sudo passwd USERNAME
passwd:Permission denied
passwd:password unchanged
root@hostname:~#
When I try to do the steps for the "The Drastic Measures", I notice that the shadow file does not show what would usually indicate an encrypted password for the user. Instead it looks like:
username:!:14920:0:99999:7:::
I have removed the exclamation point and still have issues. Even when I run
passwd
as root through recovery, I get a permissions denied error. As it stands right now, I can only log into the machine as root through recovery. I'm at a complete loss at this point and trying to avoid breaking down the machine and starting from scratch. Any help you guys can provide would be greatly appreciated.
I got MS word document, person asked me to edit it, to add table of contents, to add page numbers, because she doesn't know how to do in MS Office. So I did with LibreOffice writer. But when I saved (tried several filetypes, including: .doc, .docx, .odt) and send file back to her through facebook firefox and chrome showed error in download list saying
"Blocked: May contain a virus or spyware - "
And actually it says same thing when I download file which I sent and try to open it. And when I did edited this file second time, this time with windows and MS word, everything worked just fine.
So what's the problem here... Do I have virus which is unlikely, not even because I'm on linux, but I know how viruses works and I do not open suspicious files, I'm not going to suspicious websites and this ubuntu 14.04 LTS installed 2 weeks ago.
Something should be wrong with LibreOffice, right.. ?
Can't find any info on the internet about this issue...
And I can replicate this by creating new file with LibreOffice Writer, saved it in .odt with random text with two fonts, Times New Roman and LiberationSeriff, sent it via facebook and can not open it, same error...
Did some experiments and: it's Times New Roman font what caused the problem... What should I do? I need this font...
EDITED: So I turned off this blockage on firefox and I can download file and open it, haven't tried to open it in MS office yet, so not sure if it will work if something really wrong what libre does with MS fonts...
UPDATE: well... everything works in MS Office, nothing bad happened with fonts or document when I opened it. So everything works, but still, browser treats it as virus or spyware. :) I guess LibreOffice guys should know that...
