I recently updated by ubuntu desktop PC from 24.04 LTS to 26.04 LTS. I have a dual monitor setup, primary screen in landscape and secondary screen in portrait orientation. After turning on the PC, on the login screen, the user selection and password entry page appears on my secondary screen (which is in portrait orientation) in a landscape orientation. I could handle it if the login screen was on the secondary (portrait) monitor in portrait orientation, but this is too much. Ideally, I have my login screen on my primary monitor in a landscape orientation. I had the same exact issue on 24.04, and I don't remember how I managed to fix it, but I did, and I can't figure it out now. I'm running Wayland across the board.

System info:

• Framework 13 AMD (Ryzen), Wayland session (GNOME on Ubuntu 26.04 "resolute")
• Fresh Ubuntu install, ~1 week old
• Issue previously occurred on Ubuntu 24.04 on the same laptop and was "fixed" only by a full OS reinstall — it has now returned identically on the fresh install

Symptoms:

• Icons in the GNOME app grid duplicate themselves repeatedly (seen 20-40+ copies of the same app)
• Confirmed NOT caused by duplicate .desktop files on disk — checked both ~/.local/share/applications/ and /usr/share/applications/, only one file exists per affected app
• Happens specifically after (re)installing/launching certain apps — most recently reproduced by installing Steam via the official .deb (steam-installer package), which caused ~24 duplicate Steam icons to appear immediately after first launch
• Previous occurrence (on the old install) affected a custom GNOME extension I built, plus two other apps installed via .desktop files in ~/.local/share/applications/

What I've tried:

• Confirmed dpkg --print-foreign-architectures / apt install completed with no errors
• Checked for duplicate .desktop files (none found)
• About to try: dconf reset -f /org/gnome/shell/app-picker-layout (have not yet confirmed if this fixes it or just temporarily clears it)

Question: Is there a known root cause for org/gnome/shell/app-picker-layout duplicating entries on re-registration of an app, rather than just deduplicating? And is there a way to prevent this from recurring, since a full OS wipe did NOT permanently fix it (it returned after restoring my home folder from backup) — I suspect the corrupted dconf database itself got carried over in the restore rather than being regenerated fresh. Is app-picker-layout stored anywhere outside ~/.config/dconf/user that I should be excluding from backups?

Any pointers to the relevant GNOME Shell bug tracker issue (if this is already known) would also help.

I have been running Ubuntu 24.04 for about a year on my laptop and connections to several wifi hotspots are saved under the network settings applet. I just tried installing an additional SSD and now the system prompts me for passwords when I try to connect to any of my wifi hotspots which were already save earlier.

Possibly relevant...

1. I have not yet tried to mount or formatted the new SSD.

2. I noticed that after just plugging in the new SSD and booting up / is now pointing to the new SSD.

3. When I unplug the new drive and bootup, the wifi works fine without prompting for the credentials and I can find the credentials under /etc/netplan

Now it is possible that /etc/netplan gets mapped elsewere when adding the new SSD though I think it is unlikely. (Not able to verify it now to avoid wear and tear from opening the laptop... opened thrice already). The YAML files under /etc/netplan are named with GUID/UUIDs is it possible the file name is computed by the system at retrieval time and adding the new SSD changes the computed GUID/UUID?

On Ubuntu 24.04, from the App Center, I installed Bitwarden. After that, I was shown buttons to open or uninstall. Clicking on Open has no apparent result. If it is installed, where do I find it? If I find it, what do I have to do to access my Vault? Thank you for any help.

Recent update breaks the old recipe:

gsettings set org.gnome.desktop.media-handling automount false

gsettings set org.gnome.desktop.media-handling automount-open false

Anyone know the fix?

On Ubuntu 26.04 LTS when you search for apps in App Center (by Canonical) you cannot tell for sure if an app is a snap package or a deb package. When you open app description the header lacks the info about package type, which is really a shame.

Sometimes I can find that info by carefully reading the app description below app screenshots (which can be quite long).

Is there any a solution for that not obvious to me?

Here is a screenshot showing header info for an app:

I switched to Ubuntu and noticed that I couldn't play games well on it, so I decided to switch back to Windows. Now, when I go into the boot menu, it doesn't show my SSD. I contacted Windows support, and they told me to ask someone from Ubuntu or Linux for help. The SSD does show up in the BIOS menu, but when I try to install Windows, it doesn't appear.

I have an Acer PC.

I also tried using Intel RST, but it didn't work.

Dell Inspiron 5755 Upgraded from 20.04 to 22.04 (had a little trouble there with a package) and then upgraded from 22.04 to 24.04

Upgraded yesterday. Didn't have a problem with mouse/trackpad/and laptop touch pad. Today, I'm using Firefox and the mouse arrow locked. mouse/trackpad/and laptop touch pad all didn't work.

Then all by itself it shuts itself off.(no it didn't, SEE UPDATE AT BOTTOM)

I have a wired Elecom mouse and a Keymecher touchpad.

This only (so far) happened while in Firefox. The windows would blank out a couple of times, lock the mouse/trackpad/and laptop touch pad and then appear to shut itself off.

UPDATE: it doesn't shut itself off. I just assumed it did and I took the power cord off and removed battery before hard restart.

It happened again and I pulled the mouse & USB touch pad off immediately but the laptop touch pad was still locked. The screen goes black/blank and then it will come back to log in. So it doesn't power off all by itself.

So I have a 128 GB Memorex drive i bought from walmart years ago. Its been working fine, i can transfer files and back fine. But i cant get live media working all the sudden. It just hangs on the booting screen after i select try or install ubuntu. its not just a ubuntu thing for me. same on kubuntu. ive tried it multiple different times and still no. some help on how to fix this. I'm on a Acer Nitro 5 AN515-57-5700 NH.QESAA.004. Live was booting before though. but now no. it seems to suceed but never open the gui. (verified them also)

How do I get the USB-Wifi-Adapter Working? lsusb says:

Bus 003 Device 003: ID 07d1:3303 D-Link System DWA-131 802.11n Wireless N Nano Adapter(rev.A1) [Realtek RTL8192SU]

I tried the steps below outlined in answer to question 745697 in 2016, but the make command failed with two errors, starting with a compiler version warning: "the compiler differs from the one used to build the kernel The kernel was built by: x86_64-linux-gnu-gcc (Ubuntu 15.2.0-16ubuntu1) 15.2.0 You are using: gcc (Ubuntu 15.2.0-16ubuntu1) 15.2.0 warning: pahole version differs from the one used to build the kernel The kernel was built with: 131 You are using: 0"

Any hints? here's the guide from 2016:

1. nvidia graphic driver is not installing properly on ubuntu os.

2. nvidia graphic card is not supporting correctly. without full support of nvidia gpu the os is not complete enough.

I was setting up a backup program for my newly installed Ubuntu 26.04 when I accidentally deleted all the files (and symlinks) which reside in the root folder of my system. No folders were deleted or changed. I don't have a backup because I haven't set that up yet.

How do I restore those files and links so that the system will boot again?

I can run the demonstration mode of the installation USB to just copy or create what is necessary.

From what I gather, the main feature of Windows "Live File System" is not a Windows thing, but actually a feature of UDF revision 1.50 (1997). It added support for the "Virtual Allocation Table" (VAT), which allowed packet writing; that is, you can sort of treat the CD-R/DVD-R, which are WORM (Write Once, Read Many) as a rewriteable filesystem (not disc, filesystem).

Given this apparent generality, I imagine Linux does support this. However, I only found this, but it seems weird, since I found no udftools service nor the file where it says to be present. And I also suspect pktsetup (of Debian package udftools) has something to do with this, although I do not get its language nor explanation.

So! How do I do this?

I have a Dell Inspirion-16-5625 (Ryzen 5625) laptop and a ADATA Legend 800 SSD. I used it with Xubuntu 22.04 and 24.04 without problems. Now I updated to version 26.04 and I have at almost every cold start a system freeze after some time. Sometimes it switches to the boot screen, sometimes I can change to a console where I see a journald message saying that the file system is read only (trying to write in an endless loop), sometimes just freezes.

After a restart I often have to enter my dmcrypt password twice.

I have also Windows 11 installed which works without errors and after a warm start Xubuntu also works, so I think I can exclude any hardware problems.

I already searched in internet and I found some things:

• The SSD has a wrong implemented advanced power management.
• The graphics driver says DMCUB error.
• Read error in getting the edid of my external monitor (ASUS PA258QV)
• Dracut says the keyboard is in an unknown mode.

I tried everything I found in internet, but it seems that now its nearly at every cold start, before some cold starts worked.

So what I did:

• Update the PC BIOS
• Update the SSD firmware
• I checked the SSD with the ADATA utility in Win11 => no errors
• Set nvme_core.default_ps_max_latency_us=0 (or another value) in grub
• Set amdgpu.dcdebugmask=0x10 in grub
• Set drm.edid_firmware=HDMI-A-1:edid/hdmi.bin in grub
• Disabling the power saving modes of the SSD

For now I have no more idea what I can do. I will attach the dmesg and journal of the last freeze.

Because you can't attach something I add the logs dmesg startup errors of the last boot:

Problem Description

The built-in Wi-Fi adapter is not working under Ubuntu. The system detects the PCI device, but no wireless interface is created and no kernel driver is bound to the device.

The same hardware works correctly in Windows.

Hardware Information

Windows identifies the adapter as:

Realtek RTL8852BE-VT Wireless LAN WiFi 6 PCI-E NIC

Hardware ID:

Troubleshooting Performed

I have already tried the following:

• Disabled Secure Boot.

• Updated Ubuntu packages.

• Booted different 6.8 kernels.

• Installed and later removed the out-of-tree lwfinger/rtw89 driver.

• Reloaded the rtw89 modules.

• Verified the hardware using lspci.

• Checked lsmod, modinfo, modules.alias, dmesg, and journalctl.

None of these steps resolved the issue.

Why this question is different from:

How to solve "No Wi-Fi Adapter Found" error with Realtek RTL8852BE WiFi 6 802.11ax PCIe in Ubuntu 22.04?

I have already reviewed the existing question:

How to solve "No Wi-Fi Adapter Found" error with Realtek RTL8852BE WiFi 6 802.11ax PCIe in Ubuntu 22.04?

However, my issue appears to be different for the following reasons.

Different hardware revision

The linked question concerns the following device:

10ec:b852

My adapter is identified by Windows as:

Realtek RTL8852BE-VT Wireless LAN WiFi 6 PCI-E NIC PCI\VEN_10EC&DEV_B520&SUBSYS_88E9103C

Ubuntu also detects the device as:

03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b520]

This is a different PCI device ID from the one in the linked question.

Questions

1. Does Ubuntu 22.04 (kernel 6.8) support the RTL8852BE-VT (PCI ID 10ec:b520)?

2. Is this PCI ID supported only in newer Linux kernels?

3. Is there a newer or backported rtw89 driver that supports this device on Ubuntu 22.04?

4. Do my diagnostics indicate a configuration problem, or is this likely a missing driver/kernel support issue?

Final update (Solved):

The issue is now resolved.

My laptop has a Realtek RTL8852BE-VT (PCI ID: 10ec:b520) on Ubuntu 22.04 running kernel 6.8.0-124-generic. The in-kernel driver was either unstable or incompatible with this hardware revision.

What finally worked was installing the latest morrownr/rtw89 DKMS driver:

git clone https://github.com/morrownr/rtw89
cd rtw89
sudo make cleanup_target_system
sudo dkms install $PWD
sudo make install_fw
sudo cp rtw89.conf /etc/modprobe.d/

Initially, I tried loading rtw89_8852be, which failed with:

modprobe: ERROR: could not insert 'rtw89_8852be': Invalid argument

Looking at dmesg showed symbol version mismatch errors because I was loading the wrong module. My hardware actually uses the rtw89_8852bte_git driver.

Loading the correct module solved the problem:

sudo modprobe rtw89_8852bte_git

After that:

Kernel driver in use: rtw89_8852bte_git
Kernel modules: rtw89_8852bte_git

The wlo1 interface appeared, NetworkManager detected it normally, Wi-Fi networks were visible again, and I was able to connect successfully.

Thanks to Mr. David for pointing me toward the driver. Genuinely, thank you so much for your help.

SO. Since the beginning I always had a monitor linked to GPU with the HDMI since I wanted to be able to shut down my computer properly. But when I unplugged everything. And then linked my monitor through the Displayport only, he finally understood it was no longer an "dock + HDMI" configuration and adopt a correct response!

I guess as long I had my HDMI plugged in he would never change "his mind" about the resolution.

Hello everyone,

I am currently encountering an issue with my computer monitor link in Display-port.

My setup:

• Ubuntu 24.04.4 LTS (64-bit)

• First monitor plugged with HDMI (no issues, work just fine)
• Second monitor plugged with Display-port (detected, but not video signal). I can even move the mouse into the second monitor area.

It was working fine before I tried to connect it through a KVM dock.
This one: https://www.avaccess.com/products/idock-b23/ Then I remove it from my setup.

But since then, my monitor is no longer showing any signal, but is well detected:
My screen showing the displays connected, we can see that both screen are connected

I've tried:

• Changed my cable.
• Changed the monitor.
• Unplugged and re-plug the monitor's power.
• Update my NVIDIA's drivers
• Visual check of the GPUs Display-port integrity (no apparent issues)

Does anyone have any idea how to fix this problem?

Something went wrong when updating Synergy app and now it's impossible to do anything with the package: the dreaded (at least for me) "Sub-process /usr/bin/dpkg returned an error code (1)". I copy the log when trying to purge it:

Follow up. Sorry for the delay. I ended up leaving the city for several days. I got this:

sudo ./opt/Synergy/synergy-service --uninstall

I don't know if this is of help. Thank you.

I just upgraded my Ubuntu 24.04-4 MATE install to the latest version. I noticed that in Firefox the save dialog box refuses to save a file on the proposed location when hitting [Enter] like it always did. I first blamed Firefox but it is system-wide. Any GTK app has this unwanted behavior. Other PCs, a fully up-to-date Linux Mint 22.3 workstation and a fresh test install of Ubuntu 24.04 MATE on an HP USDT (Ultra Small Desktop) save just fine on [Enter].

But not only that, I also noticed files being overwritten without any warning when clicking Save (or using [Alt]+s). Barring a complete system re-install, how can I fix this?

I need the best way to sync Google Drive on my Ubuntu LTS 26.04 with local cache that allows me to keep working for at least a day without any internet.

Requirements are similar to Google Drive for PC:

1. Ability to work completely offline (not even internet to "mount" the drive first and then disconnect).
2. Download and caching of files when they are accessed.

What I have tried and fails:

1. rclone vfs local mount: Doesn't mount without internet! No usable cache! Can this be fixed? This is my most hopeful option currently. Here is the code I currently use:

[Unit]
Description=Google Drive Mount

OnFailure=gdrive-mount-failed.service

[Service]

2. Nautilus doesn't support native Google Drive starting GNOME 50. https://www.omgubuntu.co.uk/2026/03/google-drive-not-working-nautilus-ubuntu-26-04

3. Dolphin + Dolphin Plugins + Konqueror + KIO GDrive + KIO Admin: Can't even add the Google account on Dolphin. Page shows blank.

4. rclone bisync fails randomly and repeatedly. --resyncing has destroyed my work multiple times now. I can provide the last used code if asked.

Starting an installation of Ubuntu 26.04 with full disk wipe using the graphical installer, I have an installation stuck at rsync command for 30+ minutes after an error.

I want to make the screen grayscale because

1. It reduces strain on the eye
2. It is more effective than a regular blue light filter
3. It helps reduce unnecessary screen time

How to make the screen grayscale in KDE, Cinnamon, XFCE, MATE, Cosmic desktop and possibly other desktop environments?

The effect should work in both X11 and Wayland. It should work with all kinds of Intel/NVidia/AMD graphics cards.

Please help me for installing libtinfo5 into 24.04.1 LTS.

I almost build a program for AWE in Ubuntu 22.04.2 LTS but a new version Ubuntu 24.04.1 LTS \n \l suddenly encountered (I installed with no doubt) without libtinfo5. Then my work stopped suddenly.

Your help would be much appreciated if you could please let me know any information on the installation of libtinfo5 into the new version Ubuntu 24.04.1 LTS.

I have a rather new Lenovo P14s running Ubuntu-MATE 21.10.

How can I activate the left and right „mouse“ button on the touchpad (marked red). Currently they are completely inactive. (under Linux, not (dual boot) under Windows so not a hardware issue)

The green corners on the touchpad itself do work as mouse buttons, even hold and drag (i.e dragging around Windows on screen).

(under MATE there is no such thing as gnome-tweak, only a mate-tweak with nothing specific into this direction)

Xkill is a utility program distributed with the X Window System that instructs the X server to forcefully terminate its connection to a client, thus "killing" the client.[1] When run with no command line arguments, the program displays a special cursor (usually a crosshair or a skull and crossbones) and displays a message such as

Select the window whose client you wish to kill with button 1 ...

If a non-root window is then selected, the server will close its connection to the client that created that window, and the window will be destroyed.

I would like to achieve the same behavior for wayland windows, if possible.

PS: I am on Kubuntu 21.10 running a wayland session, but would prefer something DE agnostic.

I'd like to get a list of packages installed manually by snap and be able to find out whether a foobar package was installed manually by system installer.

For example:

Here, core, core18 were not manually installed by me (at least not explicitly), so my try was:

$ snap list | grep -v Publisher | grep -v canonical | awk '{print $1}' | tr '\n' ' '

However, I'm not sure if this is the right way to exclude automatically installed packages. Is there any neat way of doing that from the command line?

I'm using ffmpeg to add a JPG to an MP4 to make an MP4.

As there is only one image to make the video I'm wondering if there is a way to reduce the video size?

Command:

$ ffmpeg -loop 1 -i image.jpg -i audio.mp3 -shortest -c:a copy output.mp4

Results:

• image.jpg = 26.7K (image not so clear)
• audio.mp3 = 64.6M (54 minutes)
• output.mp4 = 80.6M (video result is not so clear, music still good)

Is it a reasonable size for MP4?

I am trying to install the printer onto my ubuntu system and after having installed the driver, it simply wont install. It shows me the actual printer, but I click print and nothing happens. Everything is filled out in the printer properties, but the "location" field. Is that where the printer's IP address goes?
