I have had many GPU problems in my current install of Kubuntu (I keep things as updated as possible). The previous GPU, an RX 580 8gb, had overheating issues (now found to be a hardware problem) and a system crashing issue, and now my RX 5500 xt 8gb also has a problem of randomly crashing in the game Cyberpunk 2077, and so far nowhere else. The game seems to be unstable on its own, as it can crash and glitch outside of graphics crashes. I am running it in medium graphics in windowed mode, on proton hotfix.

I have followed the guide "Dummy's guide to AMD GPU Issues", and besides enabling "amdgpu.gpu_recovery=1" in grub (which hasn't stopped crashing), this is the output I have been able to gather of all the goings-on in my system:

https://pastebin.com/knywXCRc

If needed, the crash that happens is that the game will freeze, the GPU won't send signal anymore and when it gives any signal it's all artifacts, the system being unresponsive.

I'm trying to figure out a concept on how to create a system that is installed on a RAID and has both encryption and self-healing (checksumming) capabilities, however, so far, I have failed to come up with a solution that has no issues.

Please consider the following as guidelines:

• A laptop (or other machine) that has two separate drives installed (SSD)

• Drives should be configured as RAID 1 against single drive failure, because unique data is saved onto them on the go (photos, videos, client's notes, passwords, etc.)

• RAID array should be able to boot in a degraded state, if absolutely necessary

• RAID array should be transferable, in case of laptop hardware failure (no hardware RAID)

• Data should be encrypted, because laptop is susceptible to theft and sensitive data should not be accessible by foreign parties

• (Strictly optional, but highly desired): Data should be safe against any form of corruption in the long term

I've read into a couple of different technologies that accomplish some of these criteria, but I can't make them work together to create a system that fulfills all of them. So far, I've considered:

md-raid: Does not know about data corruption, will brainlessly write any data to all active devices, whichever gets read first, gets loaded. RAID on top of encrypted block devices may fail to boot on single drive failure (?).

btrfs: Does not know about encryption. If btrfs is located on an encrypted md-raid device, it does not see individual underlying drives = no self-healing and no use for btrfs in the first place (in this specific scenario).

dm-crypt+dm-intergrity: No easy way of opening block devices (integritysetup) to boot the system, initramfs must be manually modified = no update-stability. RAID on top of encryption issue again.

ZFS: No native kernel support. Too... problematic to do.

Is there any other way to accomplish this that I have missed or anything that I got wrong? If somebody has done this before or knows of a configuration that would solve all these points, I would be glad to find a solution.

I'm trying to upgrade my Ubuntu Server to the latest LTS (26.04) from 24.04, but do-release-upgrade fails:

root@aragorn:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04.4 LTS
Release:        24.04
Codename:       noble
root@aragorn:~# do-release-upgrade 
Checking for a new Ubuntu release
There is no development version of an LTS available.
To upgrade to the latest non-LTS development release 
set Prompt=normal in /etc/update-manager/release-upgrades.

I do not want a development release, so I left the prompt to lts in /etc/update-manager/release-upgrades

How can I do it?

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 have a VPN connection configured in Settings > Netowork > VPN. I've entered the following values:

• Name: MyVPN

• VPN Protocol: Palo Alto Networks GlobalProtect

• Network gateway: https://vpn.mycomp.net

All the other values are left default, and are mostly empty.

Now, when I click connect, I am asked to log in. When I click the login button, The VPN window opens my company's log in page internally, inside itself. And this does not work, because the VPN window only supports password login, which is disabled by my company's administration, and as a result, I can never log in. What I must use instead, is passkey. The passkey login works fine through my default browser, which is Vivaldi. How can I rely on Vivaldi to log in my VPN connection?

I have atleast 1000 ubuntu servers running 18.04 with LTS support, Now i need to plan a phase wise approach to move from 18.04 to 22.04 and later plan for 24.x.

Manually updating each server takes a huge amount of time and the intended downtime associated with downloading of the packages and updating each library, kernel.....etc.

Can we replicate the upgrade packages that have been already used to upgrade lets say Server-1 and use it as a copy server to replicate across all other ubuntu servers, this saves a lot of time and bandwidth.

Ubuntu user

I have a dual boot setup with Ubuntu 24.04 and Windows 11, where each operating system is installed on its own dedicated SSD.

The issue is that after some time, GRUB completely disappears, and the computer boots straight into Windows 11. When I check the BIOS/UEFI settings, the Ubuntu partition/boot option is simply gone.

I can only get GRUB back by physically removing the Windows SSD and leaving only the Ubuntu SSD installed. After doing this and reconnecting both drives, everything goes back to "normal" for a while (though I notice that the Windows system clock gets completely messed up). However, after a short period, the Ubuntu partition disappears from the boot options all over again.

I have already tried several troubleshooting steps, including reinstalling and reconfiguring GRUB, but nothing seems to permanently fix the issue.

My hardware specs:

Motherboard: ASUS ROG Strix Z790-F Gaming WiFi  

NVMe 1: Windows 11  

NVMe 2: Ubuntu 24.04

Some relevant info...

When I list the disks and partitions in Linux, this is the output:

I tried to remove Ubuntu from window and install new Linux but the garb always pop out I think my file are still safe on window 10

I tried downloading Tuta AppImage but it doesn't run when I try to run it from file manager. I right click on the file and enabled running the file as an executable, and it still does not run. I intent to troubleshoot why it does not run, and it requires me to run it from the terminal so it will show me where it goes wrong. How do I run the AppImage file from the terminal?

Was looking up how to share my files between my two Ubuntu computers.

Found this question: How do I set up file sharing between two Ubuntu laptops on my wireless network?

But that's for 12.04. Very old. I have 24.04 and 26.04 LTS straight from the Ubuntu website.

Presuming the 12.04 was the most direct one as well, most minimal install the iso allows etc, do I still need to install openssh-server or anything, to move files over the network?

I am running Ubuntu 24.04. I was just using my laptop normally, and then suddenly the entire screen went dark. I realized that things were still happening in the background, and if i plug my laptop into a different display i can still see everything, and i can barely make out whats on the laptop screen by shining a flashlight on it. I have tried to enter recovery mode but i cannot see any of the menus since the my laptop doesn't put it on the separate display. What do i do?

Hi I installed amd graphics drivers on ubuntu 24.04 but when i go to settings -> Screen Display I still can not change the resolution. My monitor is 4K with 165 Hz, but it currently shows 3440x1400 and I can not change it.

amdgpu-install --usecase=graphics

My PC has no audio. I use Kubuntu 24.04 and KDE Plasma 5.27.12. I know nothing about computers. My monitor is a HQ 19.5". Apparently it has no audio output, but the audio also doesn't work if I try and connect earphones. I get audio only when I connect my CPU to the TV in the living room. Should I buy a new monitor?

Specifications:

   OS: Kubuntu 24.04
   KDE Plasma Version: 5.27.12
   KDE Frameworks Version: 5.115.0
   Qt version: 5.15.13
   Kernel version: 6.17.0-35-generic (64-bit)
   Graphics platform: X11
   Processors: 4 × AMD Ryzen 3 2200G with Radeon Vega Graphics
   Memory: 5.7 GiB of RAM
   Graphics processor: AMD Radeon Vega 8 Graphics

The audio system shows 2 outputs (HDMI and Pro Audio) which I can select with or without earphones connected, and I tested both with the earphones connected and there was no audio. I connected the earphones through the top and back connectors, and I tested with both outputs listed above. In the past I also tried connecting speakers to it, but it still had no audio.

I use Inkscape to run a vinyl cutter. Every time I try to use the cutter I have to change permissions using:

sudo chmod a+rw /dev/ttyUSB0

I believe there should be a way to set up permissions, possibly using groups, so that the permission is remembered and does not have to be changed every session. However, the information I have been able to find online seems to me to contradictory and confusing. I am wary of making changes without clear instructions as I am concerned about breaking other permissions.

When I run lsusb the entry for the cutter is:

Bus 001 Device 007: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC

I am using Ubuntu 24.04. I am the only user.

Is anyone able to help me with simple step by step instructions please? Any help is much appreciated, but needs to be simple as use Ubuntu as a means to an end.

For a couple weeks now, I've been experiencing random reboots on my laptop.

They happen once or twice a day or not at all, either while in use (black screen), from suspend, or at boot (-> GRUB-menu). All I do at the laptop is write texts and ocassionally game.

From my logs, these "Previous system reset reason" messages jump out at me:

• internal CPU shutdown event occured - Coincides with reboot times, except at boot.
• software wrote 0x6 to reset control register 0xCF9 - Too many, but a few coincide with at boot.
• ACPI power state transition occurred - Rare, possibly unrelated.

See sample logs HERE and HERE. (Some things are redacted.) Also, see my CPU information HERE.

Since upgrading to Ubuntu 26.04, I've had Linux kernel panics at boot once in a blue moon. Could this be relevant?

The only software I've installed within these last few weeks are VSCodium and .NET SDK.

For VSCodium:

1. snap install codium --classic
2. "Getting all telemetry out"
3. Installed muhammadsammy's C# plugin through VSCodium
4. Installed .NET SDK (see later)
5. Uninstall everything (wasn't happy)
   • Including sudo rm /usr/local/bin/dotnet (again, see later)

For .NET SDK:

1. sudo snap install dotnet-sdk --classic (or dotnet-sdk-100 when installing VSCodium)
2. sudo ln -s /snap/dotnet-sdk/current/dotnet /usr/local/bin/dotnet (for dot-net-100)
3. Added to ~.profile:
   • export DOTNET_CLI_TELEMETRY_OPTOUT=true
   • export DOTNET_ROOT=/snap/dotnet-sdk/current

What I've tried:

• Disabling Fast Boot, makes no difference?
• Running MyAsus System Diagnostics, all OK
• Keeping tabs on systemctl timers, not correlated

What I haven't tried:

• Running memtest
• Fresh reinstall
• Changing other BIOS/UEFI settings

Update 1: BIOS update

As suggested by ChanganAuto, I updated the BIOS. I followed the instructions from both "BIOS Update" and my laptop vendor's:

1. Back up my stuff plus /boot/efi/EFI
2. Download the official BIOS file (flash) for my device
3. Unzip the file, then move its content to /boot/efi/EFI
4. Use ASUS Firmware Update from ASUS in UEFI on the file

Will update if the issue still persists.

First, thanks for the feedback. I'm embarrassed because IRL, I used to do QA.

I'm trying to install Ubuntu 26.04 LTS Desktop to an external SanDisk 4 TB SSD drive from a usb microsd card reader with a 28 GB card in it.

I get the "Something went wrong" screen. This happens with two different computers.

When I click the "Show Log" button, the only message that is displayed is "No journal files were found."

This is very reproducible.

I've also tried it with a PNY 128 GB flash drive. This installation got further but encountered an error during installation.

The download checksum verified successfully.

Is there any way to verify the installation media?

I wanted to install zsh on my terminal to customise it. But after running this command: chsh -s $(which zsh). I have encountered an error message or a pop-up window that looks like this:

Any solutions for this?

How I got there: I don't have a precise idea, I think it is a problem with updates. First I had problem with Alsa mixer. My sound didnt work when I wanted to watch a video. Each time I needed to reload alsa for the computer to emit sound. After I have some updates to do, the computer would shut down and I had to turn it back on, but no update was installed and it asked again every time I turned on the PC. This must have been going on for about two months. 5days ago it shut down and I can no longer exit the console screen when I turn on the PC. I can log in.

I'm a noob on Ubuntu, I don't understand and know a lot and how it works so I searched but found nothing to help me.

I want to return to the graphic screen, I think my data is dead but I would prefer to keep it if possible.

I am currently stuck on the console or tty screen. So I tried many commands to exit:

• CTRL + ALT + Fx

  (where x is between 1 to 12) it should work but no, I just change of screen but I don't quit.

After I've upgraded from Ubuntu 24.04 to 26.04, the ls -l command behaves strangely.

I have a folder that is sync'ed with Dropbox, and files in that folder automatically get the extra attribute user.com.dropbox.attrs.

When I do a "ls -l" in a Dropbox folder, the output is something like this:

-rw-r--r--+                            1 user group      574 Nov 24  2008 z.txt

with a lot of extra spaces after the '+', which indicates that additional attributes are present.

Strangely, the number of extra spaces depends on the number of files in the listing.

This is quite annoying. Why does ls behave in this way, and how do I avoid it?

EDIT

As requested, here is a complete output from a directory using ls -l:

total 0
-rw-rw-r--+         1 user group 0 May 27 10:44 q1
-rw-rw-r--+         1 user group 0 May 27 10:44 q2
-rw-rw-r--+         1 user group 0 May 27 10:44 q3
-rw-rw-r--+         1 user group 0 May 27 10:44 q4
-rw-rw-r--+         1 user group 0 May 27 10:44 q5
-rw-rw-r--+         1 user group 0 May 27 10:44 q6
-rw-rw-r--+         1 user group 0 May 27 10:44 q7
-rw-rw-r--+         1 user group 0 May 27 10:44 q8
-rw-rw-r--+         1 user group 0 May 27 10:44 q9

And the same directory listed with gnuls -l:

total 0
-rw-rw-r-- 1 user group 0 May 27 10:44 q1
-rw-rw-r-- 1 user group 0 May 27 10:44 q2
-rw-rw-r-- 1 user group 0 May 27 10:44 q3
-rw-rw-r-- 1 user group 0 May 27 10:44 q4
-rw-rw-r-- 1 user group 0 May 27 10:44 q5
-rw-rw-r-- 1 user group 0 May 27 10:44 q6
-rw-rw-r-- 1 user group 0 May 27 10:44 q7
-rw-rw-r-- 1 user group 0 May 27 10:44 q8
-rw-rw-r-- 1 user group 0 May 27 10:44 q9

Furthermore, if I do a ls -l q[1234], I get this:

-rw-rw-r--+    1 user group 0 May 27 10:44 q1
-rw-rw-r--+    1 user group 0 May 27 10:44 q2
-rw-rw-r--+    1 user group 0 May 27 10:44 q3
-rw-rw-r--+    1 user group 0 May 27 10:44 q4

Note that the number of spaces is smaller when the number of listed files is smaller.

(user and group have been replaced for privacy.)

The default Super + something keyboard shortcuts don't work on my live session and even if I try to change it to some other shortcut key combination even not containing Super key, I can't get it work. No Super key combinations work in Window Manager settings, but some work in Keyboard settings. And Whisker Menu can be started by mere Super key release. Resetting to defaults didn't help.

I have bought a cheap new PC which I hope to put Ubuntu 24.04 or an official flavor as a sole operating system. The PC is an Acer XC-840 manufactured in September 2022 and still in box unused. Spec Intel N4505 processor ,4GB DDr4 Ram, 256 GB SSD , Intel UHD graphics , Bios R01-A2 . Hopefully this is able to run Ubuntu . I have never installed on other than very old computers and would like to know what I need to do to avoid failure . Do I need to run Windows first or can I Boot from a USB with Ubuntu ISO on and just select install using whole drive without disabling secure boot or making other changes beforehand ? As is probably obvious I am very much a beginner with Linux and would appreciate any available guidance.

When I type the command sudo python3 -m venv venv001 I get this error:

The virtual environment was not created successfully because ensurepip is not available.  On Debian/Ubuntu systems, you need to install the python3-venv package using the following command.

    apt install python3.8-venv

You may need to use sudo with that command.  After installing the python3-venv package, recreate your virtual environment.

Failing command: ['/home/mike/venv001/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']

so, I try sudo apt install python3.8-env and get the error message:

Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:

I've tried a couple of the sudo apt install -f, or --fix- commands, but still can't seem to recover from these errors.

Libre Office Calc : With ctrl-f I will get the "search Box", type in something for search a.s.o.. Next string to search a.s.o.. In former Versions of Libre Office, there were always a "search string history" present (arrow down next to the box), but now the pull down box is always empty.

Is there any configuration possible to get the "search string history" as in former SW versions ?

Perhaps I have found a reason but not a way to turn off.

Is it possible to make it independent : The LibreOffice calc "search Box" and the linux clipboard ?

after a reboot my Acer Laptop is stuck on a boot loop, in the upper left corner also appear the message "Reset System", I tried reinstalling ubuntu but this didn't solve the problem. I used boot-repair and pasted the log here:

What can I do? Thank you in advance

The file manager that came with my installation ("Simple file manager for Gnome") doesn't show thumbnails for jpg, png, and videos. I've gone to /Preferences/Search & Preview and made sure it's set to always show thumbnails but it doesn't. How can I fix this?

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??

...

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 the screwy connection cables instead of HDMI...

Never mind. Updating might not have fixed it. I will have to test later. I was confused about what output I was using.

I'm running Ubuntu 18.04.1 LTS Desktop.

I'm connecting to the desktop via remote SSH session.

I'm trying to get the current resolution for the currently active local session.

I found these seemingly relevant questions:

• How do I find out my screen resolution from a shell script?

• How can I get the monitor resolution using the command line?

• How do I change local display resolution via SSH?

However, xdpyinfo returns the following error:

xdpyinfo:  unable to open display "".

and xrandr returns a similar error:

Can't open display

I'm assuming this is because there is no display connected to my remote SSH session. I've tried switching (su) to the same user as the local session, but the error is the same - I assume for the same reason: no display related to that SSH session.

So, I tried the suggestions from my third link above.

$ export DISPLAY=:0
$ xdpyinfo
No protocol specified
xdpyinfo:  unable to open display ":0"

and

$ xrandr --display :0
No protocol specified
Can't open display :0

How can I poll the display on the active local session for resolution (dimension) info from a remote SSH session?

I'm putting together a VPS to host a game server for me and a few friends that is running Ubuntu 16.04 server edition. Right now I'm trying to configure VSFTPD to allow us to upload any files we need to the game directory and this is where I'm running into issues. I created a user named "steam" and installed the steamcmd and game into its home directory (which is all I need access to). I can connect via FTP and log in as "steam" and upload files but when I connect to the server via SSH and log in as "steam" locally my local account doesn't have access to any of the files I've uploaded. Unfortunately this is my first server I've ever tried to configure so I'm having trouble wading through all this. I've tried googling but either the problem doesn't match or it talks about something I don't understand. The closest I've come to a solution is:

Q) Help! Uploaded files are appearing with permissions -rw-------.

A1) Depending on if this is an upload by a local user or an anonymous user, use "local_umask" or "anon_umask" to change this. For example, use "anon_umask=022" to give anonymously uploaded files permissions -rw-r--r--. Note that the "0" before the "22" is important.

A2) Also see the vsftpd.conf.5 man page for the new "file_open_mode" parameter.

but I don't understand what I need to change. There is no VSFTPD.conf.5 anywhere I know. I included my conf file. All I want to do is be able to log into FTP as my local account so me and my friends can upload mission files but I don't want that account to have root access so they can't break the server.

As ZFS is now officially supported in Ubuntu 16.04, I would like to enable email notifications for my ZFS pool. Below are the steps I have taken so far, however I am now currently stuck:

• Installed msmtp and set it up to work with an external gmail account successfully.
• Uncommented and configured /etc/zfs/zed.d/zed.rc
• Set ZED_NOTIFY_VERBOSE=1
• Ran zpool scrub expecting to receive a notification of the clean scrub, no email is sent

This is the only post that I can find relating to ZFS/ZED configuration, however I was unable to get it to work: http://louwrentius.com/the-zfs-event-daemon-on-linux.html

Update: Both responses from Mumblepins and Martin led to the fix. Below are the full steps needed to get this to work:

• Install msmtp and set it up to work with an external email account (gmail or whatever)
• Install s-nail and msmtp-mta packages to map msmtp to the mail command
• Uncomment and configure /etc/zfs/zed.d/zed.rc (keeping ZED_EMAIL_PROG="mail")
• systemctl enable zed

I have been dealing with this problem for a couple of days but couldn't find a solution. I've posted on a forum before but nobody answered. Any help?

A couple of days ago a problem started to occur. I can't watch YouTube videos anymore. When I open a video, the animation goes on and on... until the message "an error has occurred". Very very very rarely sometimes a video loads. (Today it never happened, yesterday only once)

Like I said, a couple of days ago it was all working. I didn't do any updates. After this problem, I've installed every update, didn't solve the problem.

It is not browser specific, Google Chrome, Chromium, Firefox, Opera... All have the same problem. It is YouTube specific, I can watch videos on Facebook (not loaded through YouTube) and vimeo and more. I have reinstalled the flash-plugin, didn't solve. (Yet it is not about flash) It is not about my network, using the same network, Windows Laptop, iPhone, Android Tablet all load v
