Asus motherboard Logo manufacturer appears twice when booting to grub menu with dual boot.

I have solved this problem by doing the boot repair using ubuntu live USB and after that in the bios options, I have changed the CSM (Compatibility Support Module):option

from other OS to windows UEFI boot. Now computer shows logo once and after that grub menu shows up.

I'm new to Linux, but haven't struggled with an issue like this. A few minutes after restarting today, I noticed my Left and Up Arrow keys behaving weirdly, and, after some research, tried running the evtest command. It failed to install the first time, and after some time looking into that, then other possible solutions, followed by a restart (upon which I found the issue persisted), I tried again, and when first successfully running the command, it displayed the expected inputs for Left Arrow and Up Arrow.

I thought this was weird, and, in the process of writing a question here, realised the inputs were, in fact, normal, and the issue seemed to have resolved itself, so I deleted the drafted question and hoped for the best.

But a few minutes later, somehow, it's back, and this time, when running the evtest command, I did get something else:

The first two sets of events are Left Arrow, the second two are Up Arrow. I should note that Left Arrow also occasionally opens the Context Menu, as if I had pressed Right Mouse Button. These two keys are the only ones behaving oddly, and, while briefly testing another keyboard, its own worked just fine, despite both keyboards being plugged in and tested at the same time (unfortunatly, I can't use the other keyboard for more than testing, as a few of its keys have stopped working altogether).

I'm running Ubuntu 26.04 LTS.

I am using Ubuntu 24.04 LTS. I have a directory located at ~/Documents/myfiles/....

About one day ago, this directory contained at least seven subdirectories with various files, mainly .odt (LibreOffice), .doc documents, and some source code files such as C++ headers and implementation files (.h, .cpp), as well as Java classes.

Yesterday, I closed my laptop without shutting it down, and it remained in sleep mode for about a day. When I opened it today, I noticed that almost all files and folders inside that directory had disappeared.

I am confident that no one else had access to this laptop during that time.
There is more than enough free space.

I would like to understand how this could have happened. Is there any way to track file or folder deletion history in Ubuntu? I checked the history command, but I did not find any commands such as rm or anything that would indicate manual deletion.

Upd1 This is the output of the command lsblk -e7 -o model,name,size,fstype,label,uuid,mountpoints Mian system where files disappear is nvme0n1

Starting around May 13-20, 2026, every time I wake my Ubuntu 24.04 machine from sleep or log in after a restart, I have to enter my password 2-3 times before it finally accepts it. The login screen seems to accept it, then immediately re-prompts. It's been consistent ever since.

Looking at the logs, I see this on every login:

gdm-password: gkr-pam: unable to locate daemon control file

gdm-password: gkr-pam: stashed password to try later in open session

I found some older Ask Ubuntu answers about this (How to solve: gkr-pam: unable to locate daemon control file? The login keyring did not get unlocked when you logged into your computer), but they're from 2010-2020 and mostly suggest PAM config tweaks that feel outdated. Has anyone else hit this recently? Any modern solutions?

On installing Ubuntu Studio 26.04 from scratch, I ended-up with an unusable system due to the screen getting scrambled+lockup at random moments several times per day. I have likewise experience on Ubuntu 25.10. This scramble+lockup was not there on earlier versions. HW has - amongst others - a Geforce RTX card driving my monitor. Googling around suggests that there is an incompatibility-issue against wayland. Before I ditch this (not exactly cheap) video-card, what options do I have? I know that I can workaround back to Xorg to some point, however, that can only be a temp workaround as all distro's seem to be forced to move to wayland. So Xorg is likely to become a narrower path every day.

I'm running ubuntu desktop 24.04.4 LTS on x64 bare metal.

#apt install debuginfod delivered version 0.190-1

I want the debug symbols, but I am not using gdb.

I export DEBUGINFOD_URLS="debuginfod.ubuntu.com".

But when I run debuginfod, it just hangs after printing some startup messages (last one is "groomed database in xxxs) but no errors or warnings.

ping debuginfod.ubuntu.com is successful, and browsing to http://debuginfod.ubuntu.com redirects to https://ubuntu.com/server/docs/how-to/debugging/about-debuginfod/ , so it seems the server is alive.

Any suggestions?

I lost my mobile and to recover my email, gallery, etc., which was synchronised with my Gmail account, but Gmail is asking for my G-code/OTP, which was sent to my lost number sms so how to retrieve

Yesterday I upgraded from Ubuntu 24.04.3 LTS to 26.04 LTS and whenever I boot, after the BIOS screen, the video output stops. My monitor says no video. I had a similar problem with this computer about 6 months ago when I tried to upgrade to the latest non-LTS version for a brand new RTX 5000 graphics card, which I ended up returning and reinstalled 24.04.3 LTS. I am surprised this issue has not been fixed in the LTS release. My hardware is ASUS TUF Gaming X570-Plus WiFi, Ryzen 5 5600X, XFX Radeon HD 7870.

Referring to @Mausy5043 in another post.

My mousepad is not working correctly (not responding always). It's been progressive and if I force it, pushing stronger, it may work but getting worse

Now I also checked this is a bug because if I use the touchpad with 2 fingers it immediately works and I can then follow with only one fingers almost normally. But if I take the finger off I'm back to being off. I can only connect with two fingers. Any operation only works with 2 fingers. Is it a setting? I don't think so.

I have a fresh install of Ubuntu 26.04 on a Dell R720 server. It has an integrated Matrox G200eR2 GPU (iGPU). I have installed two NVIDIA Tesla CMP 100-210 GPUs (graphics accelerators without video outputs, very similar to model V100). I'll call these dGPUs for conciseness. I have installed the NVIDIA proprietary drivers. I want to run Gnome/Wayland on the Matrox iGPU and leave both NVIDIA dGPUs for running a local LLM. I cannot figure out how to do this.

With no NVIDIA kernel parametes in my /etc/default/grub:

If I remove both dGPUs, Gnome loads just fine on the iGPU and runs perfectly. If I install either single dGPU into either of the two available dual-slot x16 PCIe slots (both on risers) in the server, Gnome still loads fine and runs fine. If I install both dGPUs (either one in either PCIe slot), Gnome will not load. When booting gets to the point where Gnome should load, there is a blinking or solid cursor in the top left of a black screen. If/when the cursor is blinking, I can use Ctrl+Alt+F3, etc., to get to a TTY. When the cursor is solid (this happens intermittently), I can't get to a TTY unless I wait a while. Regardless, I can ssh into the machine.

With "nvidia_drm.modeset=1" kernel parameter added to /etc/default/grub, Gnome will load with both dGPUs installed but it is very slow/laggy.

Whenever one or both dGPUs are installed, nvidia-smi shows /usr/bin/gnome-shell running and loaded into dGPU VRAM. If, and only if, the "nvidia_drm.modeset=1" kernel parameter is active, /usr/bin/Xwayland is also listed as running and being loaded into dGPU VRAM.

I can get it to boot & run Gnome/Wayland (usably fast but with low resolution) if I boot from a Ubuntu 26.04 live USB with "safe graphics" *without* the proprietary NVIDIA drivers installed.

I can get X11 to run fine on the iGPU if I switch to lubuntu-desktop so it uses SDDM and LXQT rather than GDM3/Gnome. In this scenario, nvidia-smi shows no processes running on the dGPUs and no VRAM used.

If I install & run NVIDIA prime-select, it says "Error: no integrated GPU detected."

I don't know what else to try. It's probably nit-picky of me, but I would much rather run Gnome desktop than LXQT or XFCE, but Gnome 50 under Ubuntu 26.04 only supports Wayland and not X11.

Does anyone have any ideas?

I followed the same steps on 26.04 for overlayroot that I used on 24.04 and it doesn't work.

sudo apt-get install overlayroot  
sudo nano /etc/overlayroot.conf  

set overlayroot="" to overlayroot="tmpfs"

write out

df -h shows /dev/sda2 is still being mounted on / when it should be mounted in a write protected state. Any changes made do persist between restarts.

How can I get this to work properly?

I would like to install Kubuntu 26.04 on my Acer Swift SF714-52T (2019) that is currently running Linux Mint.

I created a bootable USB on a Windows desktop using Rufus.

The first time I tried to install it, I successfully reached the GUI installer, and completed all the steps up to indicating my username, etc. At this step, the screen froze, and my computer rebooted.

Now, every time I try to install it, I get a kernel panic: VFS unable to mount root fs on unknown-block(0,0) error.

Secure Boot is disabled; I tried to create the USB image with almost every possible option in Rufus (and with balenaEtcher and the Linux Mint disk manager...). I tried safe mode, but I get the same result. I also tried Kubuntu 24.04.

Additionally, I tried installing Ubuntu 26.04 instead, but I get stuck with a GRUB terminal (I'm not sure it is called this way).

I use an Asus Vivobook 15. There is a sign on fn button which says fn+esc. This combination switches from fn keys to let me use directly the volume and other function keys on fn buttons. The problem is Ubuntu always forgets if i switch to multimedia keys after i turn off the laptop. I checked the bios settings and there is only one option for it which just turns off the ability to switch between the two. Is there any other solution?

Cannot restore files in a Deja-dup v50 Archive 26.04 generated from same on 26.04.

My understanding is that you now cannot restore files directly from nautilus. However, when I attempt to restore a file, I select my archive (from Deja-dup archive selection) and it goes into nautilus. Is this right? It is a file selector of some sort, anyway, but there is no mechanism to initiate a restore. Right and left click does not reveal anything and I cannot see any more buttons

I use a 24.04 and 26.04 with a common /home. So when it was installed on 26.04 it would have inherited the 24.04 customization files if there are any. I know there is something in `~/.cache` but I couldn't identify anything relevant to this.

I have also looked in dconf editor and I couldn't find anything relevant in there.

I now assume that Deja Dup v50 is not compatible with Deja Dup (current version in 24.04) as when I logged into 24.04 it could not identify any archives at all. I did check it was pointing to the same place as in 26.04.

Questions. Can you fix the restore?

Should I keep 24.04 and 26.04 completely separate? Note: I suspect the two versions are sharing the setup data that dconf editor is pointing to which will make this a little tricky.

Thanks for any help given.

I'm using Openoffice since about 30 years. At the time it was called Staroffice. As my Laptop is not able to run win11, Finaly I took the opportunity to replace win10 with ubuntu 24.04.04.

Libreoffice is included with this version. But I don't like the user interface of Libreoffice. It's very scattered. I really prefer Openoffice, because it's simple and clear.

Question one: Is there a possibility with Libreoffice to select a kind of simpler user interface as OpenOffice is using. In this case I would mind to change, even than I think Libreoffice is suffering of code bleeding in an unsane manner!

Question 2 if Q1 is not possible, I will stick to Openoffice. I feel confortable with it. There is only one strange behavior. OpenOffice is 32 bit. And until now for this it required 32 bit Java as JRE 8. Hence I installed the jre 8 version for linux. It is there, and being in the jre/bin directory I get the rigth version. But, for development I use Java 26! normal 64bit version. So if I try to select java within Openoffice it recognize only this version 26 or 17 which is also still on the computer. But what ever I try to make Openoffice understand to select the Version 1.8 JRE, it tells me. No valid java found in the given directory! Even if I delete any selection, 26 or 17 is offered to select automatically and immediately! The question is would OpenOffice nevertheless work with one of those 64bit version, why OpenOffice tells me so stubborn no valid Java program found? I set it within /etc/alternatives, and in the path, and in the path of Openoffice, etc.! always no java shown, and not possible to select, apart the 64bit versions of course!

Booted from USB drive, selected "Try Kubuntu", ran the installer, chose "Normal Installation", selected SSD, chose "Erase disk", checked "Encrypt system", entered encryption password, and continued with the rest of the installation process.

Towards the end of the installation (feels like towards the end, although I'm not sure if it leaves something out), the installer shows an error message "could not close encrypted partition on the target system". However, after closing the installer and manually rebooting, the system seems to be working. But I can't be sure if something is broken somewhere.

I later tried the same installation steps inside VirtualBox, and it works just fine. It's only on my laptop where this error shows. What should I do? Is it safe to continue using it despite the error and "failed" installation?

I recently upgraded to Déjà Dup 49 and noticed that the restore workflow seems to have changed compared to older versions.

In previous versions, I could navigate to a specific folder path and then browse the available backup versions while remaining in that folder. This made it easy to inspect multiple snapshots and find the version I wanted.

In Déjà Dup 49, the workflow appears to be reversed:

First select a backup date. Then navigate through the folder hierarchy to the desired path.

The problem is that if I want to inspect a folder across many backup dates (for example, 10 different snapshots), I have to repeatedly:

go back, select another date, navigate through the same folder tree again.

This feels much less efficient than the previous workflow where I could stay in the folder and move between backup versions.

My questions are:

1. Is there an option in Déjà Dup 49 to restore the old browsing behavior?
2. Is there another way to efficiently browse multiple versions of a specific folder without repeatedly navigating the directory tree?
3. Was this change intentional, and if so, what was the rationale behind it?

In addition, I have a large collection of existing backups that were created by Déjà Dup using Duplicity. If the old behavior is no longer available, are there any alternative GUI front-ends that can browse and restore existing Duplicity backup archives?

I'm specifically looking for a graphical application that is backward-compatible with existing Duplicity backup repositories, since I do not want to recreate years of backups from scratch.

I'm using Ubuntu and Déjà Dup 49.0.

Any suggestions would be appreciated.

I use MystIQ to convert videos to MP4. It works great most of the time, but on some videos (usually .mkv format) it doesn't convert the sound correctly. I open MystIQ up, go to add a file, then select the file and then select the directory where to put it and then hit "convert". It gets the video with the music track, but it doesn't get the voice track. Is there some setting that I need to change, or maybe there's another app that works better? From the comments I have received, I guess you are supposed to select the audio file? I just select a video file and then select 'convert'. Guess that isn't enough.

Screen sharing when using Microsoft Teams from a browser (firefox, in this case) used to be simple, but since Ubuntu 26.04 uses GNOME without X11 support, only Wayland, the situation changed. Wayland is more secure than X11 and makes it harder for one app access the contents of other apps windows.

If I try to share the screen in Firefox (149.0.2, distributed with Ubuntu), the following happens: first, a dialog appears:

I click on "Allow", select the display to share, briefly a screen sharing icon appears in the GNOME toolbar:

and then disappears. Screen is not shared. The same thing happens if I try to share a window, even a Firefox Window. How can you share a screen with Teams in Firefox on Ubuntu 26.04?

I'm on Ubuntu 24.04 and I have the 9.something version of Wine installed. I have a few games which require running a .bat file (since it wasn't made for Linux) in order to work. When I try to right-click -> Open with wine installer, nothing happens. Then I tried this:

~$ wine cmd.exe /c home/myself/Downloads/thegamefiles/Start—thegame.bat

I got this result:

007c:err:ntoskrnl:ZwLoadDriver failed to create driver L"\\Registry\\Machine\\System\\CurrentControlSet\\Services\\winebth": c0000135
Can't recognize '/home/myself/Downloads/thegamefiles/Start—thegame.bat' as 
an internal or external command, or batch script.

What is the problem and how can I get this to work?

I also tried to make a .sh copy of the file (with #!/bin/bash instead of @echo off), but the terminal tells me command not found for every line. edit: As asked I made this output on the terminal

~$ ls -l /home/myself/Downloads/thegamefiles/Start—thegame.bat

And I got this:

ls: cannot access '/home/myself/Downloads/thegamefiles/Start—thegame.bat': No such file or driectory

And I can also give the code inside the bat file :

@echo off
title title of the game
echo.
echo   ++++++++++++++++++++++++++++++++++
echo          title of the game
echo         the game
echo   ++++++++++++++++++++++++++++++++++
echo.
echo   Opening browser...
START http://127.0.0.1:29595/
echo   Starting server...

echo   Closing this window will stop the server
"server/miniweb.exe" -p 29595 -i 127.0.0.1 -r game/thegame >nul 2>&1
echo.
echo   Shutting down...
echo.

another edit: the game's folder is organised this way => there's the Start-thegame.bat file and two additional folders named "Server" (where there's just the "miniweb.exe file) and "Game" which contains another folder which in turn has a html file,and dozens of folders with pretty names such as "d5dc1e3202d89e15b3f5675fab7b1c86" with a binary file inside every single one of them.

new edit: I tried to do as told in here with this command:

wine cmd c/ /home/myself/.wine/drive_c/users/myself/Downloads/thegamefiles/Start-thegame.bat
0080:err:ntoskrnl:ZwLoadDriver failed to create driver L"\\Registry\\Machine\\System\\CurrentControlSet\\Services\\winebth": c0000135

I ran USG under earlier version of Ubuntu but it does not appear to be available on 26.04. Is there a replacement? I see there is a compliance section on the security center but there is a big splash screen that says it is only recommended for certain hardneing requirements and everything is greyed out.

Disclaimer, I’m posting this to help out anyone having issues with their intel MacBook no t2 chip cause I went through hours of troubleshooting and don’t want anyone to go through that. Also I’m new to the linux world so Claude was a huge part of this and fixed all of my issues. I installed Ubuntu 26.04 on a MacBook Pro 13" 2017 No Touch Bar (A1708 / MacBookPro14,1). This model does NOT have a T2 chip.

Out of the box I had these problems:

• Closing the lid appeared to suspend but the machine stayed fully awake (hot, battery draining fast)
• Manually suspending caused a complete hard freeze requiring a force reboot
• WiFi, keyboard and trackpad didn't recover after resume
• Audio showed as "Dummy Output" — no sound at all
• FaceTime HD webcam not detected

How do I fix suspend, audio and the webcam on this model?

I've been eagerly waiting for Ubuntu 26.04 LTS because I knew ROCm would be installed automatically with it. Now I'm disappointed to see it's only ROCm 7.1.0 / 7.1.1 which does not work well with newer AMD Strix Halo designs like AMD RYZEN AI MAX+ 395 with Radeon 8060S (gfx1151).

To get the full potential of this GPU and NPU, I have to use ROCm 7.2 and later. First question is:

• Should I install ROCm 7.2 myself despite there is not even an installation guide for Ubuntu 26.04 in the official documentation yet, or
• eagerly wait for a ROCm update to come to Ubuntu 26.04 via system updates?

I would happily wait 1 or 2 months, but if this update is not to be expected in the near future then I most likely would have to do it myself. How to start?

I'm struggling to access an MCU connected to the USB and presented as a serial port: /dev/ttyACM0. What worked well in Ubuntu 22.04 does not work in 24.04. Whenever I connect the device, the only way to have it access is to chmod 666 it, but that works only temporarily.

The user I'm working on is already added to the dialout group, and ls -l /dev/ttyACM0 returns: crw-rw---- 1 root dialout 166, 0 Oct 25 15:33 /dev/ttyACM0 , so as I can understand it, it is the root who has r/w and any dialout group member. Am I missing anything here to configure/add?

Edit: The driver seems to be correct so that is not the case of invalid UDEV rule triggered:

I'm struggling a bit with running Timeshift from command line. My disk structure look like this:

sda                         8:0    0   1.8T  0 disk
├─sda1                      8:1    0   512M  0 part /boot/efi
├─sda2                      8:2    0     1G  0 part /run/timeshift/backup
└─sda3                      8:3    0   1.8T  0 part

└─sdb1                      8:17   0 232.9G  0 part /run/timeshift/backup

So, I would like to create a backup on the sdb1 disk, using:

sudo timeshift --create --comments "Test" --tags D --snapshot-device /dev/sdb1

gives me the following:

Mounted '/dev/sdb1' at '/run/timeshift/backup'

Any suggestions on what I am doing wrong?

I have TightVNC installed and working on my Ubuntu 18.4 virtual server, following this guide. It says to use nano and create a 'unit' file called /etc/systemd/system/vncserver@.service. It then specifies the contents of the file, and I have checked and double-checked, but when I try and start the service with:

systemctl start vncserver@1

I get an error that says:

Job for vncserver@1.service failed because the control process exited with error code.

Then I run:

systemctl status vncserver@1.service

and I get this output:

Any ideas or suggestions as to what might be wrong? I am a total Linux novice, working on a Digital Ocean VPS's web-based terminal.

On Ubuntu 18.04 both journald and rsyslog are installed. Both serve the same purpose of collecting log messages and storing them. So we have two programs doing the same work here.

What I could find out is that journald only saves log messages in its own journal files which can be queried with the journalctl command. No readable files are written. Also, journal will always collect log output from all the services that were started by systemd, which should always be all of them because ultimately systemd starts all processes even from older schemes like init scripts.

Rsyslog also receives log messages, through some socket that works like syslog has worked the past 50 years or so. Applications have to send their messages to that socket and rsyslog will receive them. Not sure how journald actually receives anything. Then rsyslog forwards these received messages into different readable files as per its configuration.

In Ubuntu, both are installed but do not seem to be connected. At least rsyslog does not load the "imjournal" module with which it could "read" log messages from journald. I don't understand how rsyslog (actively) reads anything, I thought it only (passively) receives messages. But it's not using that anyway.

The file /var/log/syslog contains largely the same content as shown by journalctl, just the output from sudo is missing in the file. But I haven't compared it all.

So how does this work? Who sends log messages to where and who receives them and where are they forwarded to? If both destinations are filled, does every application have to send messages to both syslog and journald separately? If they are interconnected, why are no messages duplicated? Are they filtered out again? Which location is more complete and where should I look if I want the complete picture?

If any of this has changed in newer versions of Ubuntu, I'd also be interested in that, as I'm going to switch an older server to 20.04 next year.

Edit: Here are some more resources on the topic:

• [Interaction of Rsyslog and Journal (Red Hat sysadmin guide)](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/system_administrators_guide/ch-viewing_and_managing_log_files#s1-interaction_of_rsyslog_and_journal
• imjournal (rsyslog documentation)
• rsyslog journal integration, Video presentation by the rsyslog author
• The syslog system call
• Coexistence with systemd (rsyslog documentation)

All of this information leaves me a bit confused. It seems like journal receives all syslog data from the system call in the first place (my /dev/log points to /run/systemd/journal/dev-log), and rsyslog fetches it from journal through a socket that looks like the socket that is had used before there was journal (possibly /run/systemd/journal/syslog, implicitly used if it sees systemd around). Then rsyslog can do all its advanced log processing (including writing the legacy /var/log files). If I don't need any of that magic, I might just disable rsyslog. But I'm not sure about that at all!

I'm using Ubuntu GNOME 17.04. One encounters client side decoration (CSD) as most of the official GNOME applications (Nautilus, gedit, Evince etc.) use GtkHeaderBars (a combined title bar and toolbar, see linked screenshots) whereas other applications don't. This feature is disabled in Unity, all the applications use traditional separate title bars.

Screenshots (from this article):

• Nautilus with GtkHeaderBar

  

• Nautilus without GtkHeaderBar

  

For consistency I want to disable GtkHeaderBars globally (in all the applications using it) and use separate title bars. Is there a way to achieve that?

I have heard of gtk3-nocsd package, but couldn't make it work with GNOME for all the applications.

How to prevent Muon from asking a password when installing updates?

Adding user ALL=(ALL) NOPASSWD: ALL to sudoers does not help. sudo apt-get upgrade works without a password, but Muon is still asking for it.

It is very annoying to enter password every day to install updates.
