So I bought Spiderman Remastered on Steam to play it on my Ubuntu computer , and I try to launch game on steam using proton experimental and I get a message that says "no graphic card detected"
in my laptop I have a intel Iris Xe , 16go RAM , intel core i5 , and other games (like cyberpunk 2077) are working without problems
I am a new Ubuntu user who's having trouble getting .CR3 files to show thumbnails on Nautilus. I tried adding the appropriate MIME Type to my thumbnailer file: image/x-cr3;image/x-canon-cr3 (and several other variations pasted from a massive list of RAW photo file types). I saw that the previous question about this same issue was never answered, so I am not sure where to go. I followed the tutorial in this YouTube video.
I purchased two new monitors and a DP hub to build a three-monitor trading setup with a mini gaming computer. The hub will not connect to both DP displays simultaneously (see below). My only luck was to connect one screen (direct or through the hub) to use the terminal and do some digging. I am an Ubuntu newb, so be warned that I have had Gemini assist me in the trouble shooting session.
My goal: I am looking for a confirmed DisplayPort 1.4 MST Hub that works with the amdgpu driver on Ubuntu 24.04.4 LTS.
My Hardware: CPU/GPU: AMD Ryzen 5 5000 Series (Lucienne) Integrated Graphics. Monitors: 2x BenQ GW2791 (1080p @ 100Hz) via MST Hub, plus 1x KTC (1080p) via HDMI. Current Hub: Generic "Aibilangose" DP 1.4 Powered MST Hub.
The Problem: When connecting both BenQ monitors to the hub, both screens show "No Input" and xrandr reports the ports as disconnected. If I unplug one monitor, the remaining one works fine.
Logs & Errors: Running dmesg reveals the following repeating error whenever the second monitor is plugged in:
amdgpu 0000:04:00.0: [drm] ERROR Sending link address failed with -5 [drm] DM_MST: stopping TM on aconnector...
It appears the driver is failing the MST handshake/link training. I have tried forcing 60Hz and 720p via xrandr, but the port continues to drop to a "disconnected" state.
Firmware: "System BIOS: PM6B0_08.3200_28W (Date: 01/20/2025)" "VBIOS: 113-LUCIENNE-017 (ATOM BIOS)"
Question: Does anyone have a specific brand/model of DP 1.4 MST Hub (e.g., Cable Matters, StarTech, Club3D) that is verified to work with the amdgpu driver on Kernel 6.8+ without this timeout error? I need to drive two 1080p displays (ideally at 100Hz) plus a third via HDMI.
I appreciate everyone's help.
I have a weird issue with a convertible (ThinkPad S230u) and Ubuntu 24.04 LTS: When it changes to tablet mode (which works fine, including autorotate) libinput disables the keyboard, touchpad and trackpad. So far, so good. But unfortunately the tablet buttons (Windows/action , Volume Up, Volume Down & Lock screen) get disabled as well since they send their data over the keyboard interface as well.
But this means that in tablet mode the tablet is not working properly. Is there any way to edit this behaviour or deactivate the disablement of the keyboard and touchpad?
Since it's a classic convertible the screen covers the plamrest anyway, so the keys can't be pressed by accident.
OS: Kubuntu 24.04, kernel version: 6.8.0-94-generic (64-bit)

I dual boot windows and kubuntu + linux mint. I used to be able to connect to the school wifi just fine, with an even better experience than on windows. About a year ago I began to have this issue of linux indicating that I am connected to the school wifi but not being able to use the internet although the internet works on windows and on my android phone, leading me to abandon linux. To connect to the school wifi, there is a portal for school credentials. Does anyone know what is wrong?
I have an HP Elitebook laptop running Ubuntu 24.04 LTS. I sometimes play the sound through the laptop speakers and sometimes through the HP dock, which routes it through HDMI. If there has been no sound for some period, there is a multi-second delay in the start of the sound. This is mostly just annoying, though sometimes if the sound is just a 'click' indicating a chess game move, for instance, the sound just doesn't show up. I have no power issues to worry about. I would like to do something to my system so that it does not have a delay when starting sound.
I did a Google search on the question; it tells me to edit a file that doesn't exist in the directory where the directions tell me it is. Then the setting it is telling me to use is wildly different from the setting as it is, and I cannot even tell the units for the value I'm setting. I decided that, in this case at least, blindly following what the Google AI tells me to do was not what I wanted.
Also, AskUbuntu sound question gives instructions about how to create an 'empty' sound and start a daemon to play it continuously to fool the system into thinking there is a sound in progress. I think I can do that, but is it really necessary? Isn't there some driver or something that can merely be told not to delay that much? Ot at all?
I am trying to add the Virtualbox repositories to Ubuntu 24.04.4LTS
The instructions are here.
I downloaded the key from https://www.virtualbox.org/download/oracle_vbox_2016.asc
And placed it in ~/Downloads/Virtualbox/oracle_vbox_2016.asc
I then added the key to /usr/share/keyrings/ with
sudo gpg --yes --output /usr/share/keyrings/oracle-virtualbox-2016.gpg --dearmor ~/Downloads/Virtualbox/oracle_vbox_2016.asc
So I now have /usr/share/keyrings/oracle-virtualbox-2016.gpg.
Next I have to deal with the line
deb [arch=amd64 signed-by=/usr/share/keyrings/oracle-virtualbox-2016.gpg] https://download.virtualbox.org/virtualbox/debian <mydist> contrib
The GUI at 'Administration > Software & Updates` doesn't like the bit in brackets [...].
Neither does, add-apt-repository.
So now I'm trying to manually add everything to /etc/apt/sources.list.d/ubuntu.sources.
The current ubuntu.sources is
Types: deb
URIs: http://gb.archive.ubuntu.com/ubuntu/
Suites: noble noble-updates noble-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
Types: deb
URIs: http://security.ubuntu.com/ubuntu/
Suites: noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
So I'm guessing I need to add:
Types: deb
URIs: https://download.virtualbox.org/virtualbox/debian
Suites: *1
Components: *2
Signed-By: /usr/share/keyrings/oracle-virtualbox-2016.gpg
But what do I put at *1 and *2 ?
Given that the Oracle deb line ends, <mydist> contrib, do I simply put noble at *1 and contrib at *2 ?
A couple months ago I dual booted my Lenovo Thinkpad (2014) to run Windows 8 and Lubuntu. In doing so I needed to disable secure boot and fast start up. I also set the boot manger to place Lubuntu as the primary OS.
With a recent update and restart to Lubuntu in the first two weeks of February 2026, I encountered this error:"Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)"
The system had been running smoothly until now and been updating consistently. I didn't notice initially until now that I can not access the Linux system GRUB menu. I can access the Lenovo Diagnostics menu, the BIOS menu and Windows Boot Manager Menu. The pressing of the shift and esc keys do nothing.
How do I obtain access the GRUB menu so I can fix my kernel panic issue?
Pressed ESC/shift repeatedly - Nothing. Currently running 24.04 LTS What is HWE /GA installed media?

I previously put on hold the kernel update on a system as the updates were breaking the system. This was described in this question.
I came across this article:
The Ubuntu 24.04.4 LTS hardware enablement stack (HWE) has finally hit the updates repo, bringing Linux kernel 6.17 and Mesa 25.2.7 to users on the current long-term support release
As such I unheld the kernel using this command and installed the linux-headers-generic-hwe-24.04:
$ sudo apt-mark unhold 6.14.0-33-generic
$ sudo apt update
$ sudo apt install linux-headers-generic-hwe-24.04
However the installation failed because of btusb/4.2. According to AI, I could resolve this issue by removing that bluetooth app
I then removed it and reinstalled linux-headers-generic-hwe-24.04:
$ sudo dkms status
$ sudo dkms remove btusb/4.2 --all
$ sudo apt clean
$ sudo dpkg --configure -a
$ sudo apt update && sudo apt upgrade
$ sudo apt install linux-headers-generic-hwe-24.04
$ uname -a
However 6.14.0-33-generic #33~24.04.1-Ubuntu is still being used.
I rebooted my system and updated the system but still the kernel was not updated. I discovered another problem. The multi-screen display no longer worked and only one monitor would appear. I verified that this issue was unrelated to any hardware issue and is a software issue.
Consequently, went into the terminal mode via Ctrl + Alt + F3 to reinstall purge the nvidia drivers, reinstall the current working linux kernel and reinstalled the nvidia drivers:
$ sudo apt remove --purge nvidia-*
$ sudo apt autoremove
$ sudo apt autoclean
$ sudo apt install linux-headers-$(uname -r)
$ sudo ubuntu-drivers autoinstall
$ sudo reboot
After the reboot, the multi-monitor displays worked again. I reinstalled linux-headers-generic-hwe-24.04:
$ sudo apt remove --purge linux-headers-generic-hwe-24.04
$ sudo apt install linux-headers-generic-hwe-24.04
However, the Linux kernel 6.17 was still not showing up. Also bluetooth can no longer be enabled.
How do I get the Linux kernel 6.17 to be loaded and get the bluetooth to work again?
I confirm that linux-headers-generic-hwe-24.04 is installed.
$ sudo apt install linux-headers-generic-hwe-24.04
Reading package lists... Done
Building dependency tree... Done

linux-headers-generic-hwe-24.04 is already the newest version (6.17.0-14.14~24.04.1).

However, the linux kernel does not shows to be updated:

Ubuntu Studio 24.04.1 LTS (KDE 5, kernel 6.8) on a Dell Precision M6800 Mobile Workstation. It was rock-solid before, but I thought I'd upgrade the WiFi, since I found a forum post elsewhere that claimed success. So I got the exact model from that post, and swapped it in:

So I swapped back to the old card, same configuration as before, and it wouldn't finish booting! First time it's done that in a VERY long time! It got as far as the second splash screen, after auto-login, for loading the user's settings, and then hung there, gear spinning for far longer than it normally does.
Eventually I gave up, held the power button to force it off, took the card out, and tried to run it with no WiFi card at all. Same thing again: hung on the spinning gear after auto-login.
So I went back to the one configuration that worked - the new WiFi card - and it STILL did the exact same thing: hung on loading user settings.
Then I went into the BIOS and got this, still with the new card:
After that, it finally finished logging in, in the same time that it normally takes, but I don't know how or why since I didn't change anything. Still no WiFi.

Fortunately, my home dock is wired, which is how I'm posting this, but I do need WiFi when I take it places. At this point, I'd be happy if either card worked, but of course I'd still prefer the new one. Any ideas?
I just started seeing the message "Sorry Command Output has thrown error" on my lock screen and I have no idea what caused it. I have the lock screen extension so I thought it could be related but I don't see any options in it that could cause this error. Also, the time and date used to be white but now they're this blueish color.

Yesterday my Ubuntu 22.04 started to randomly crash to a black screen. When this happens I no longer have access to my computer in any way except by holding down the start button to power off the computer. Why does this happen, and how to fix it?
I have a fresh install of Ubuntu Studio 22.04. Proprietary nvidia drivers 510.60.02. The screen will sometimes get fuzzy. It's not constant and doing things like typing or moving the mouse will cause it to become un-fuzzy briefly.
Logging out of my X session and logging back in fixes it.
The two times I've noticed it happening the triggers appear to be either exiting a game or after the screen/screensaver has been on a long time (over night).
I'm actually able to screenshot it, so here's what I see:
Fuzzy Ubuntu Studio 22.04:

In Ubuntu 20.04, after download from various ways (snap or ubuntu software) the visual studio code text editor, I had not been able to find a way to install the shortcut command line vscode or code.
I used alias by open the current path:
alias c.='(code $PWD &>/dev/null &)'
But since this won't work without the line command code.
I tried the suggestions found here, to open Visual Studio Code and press Ctrl+Shift+P then type >install shell command but I got command not found.
I have installed Kubuntu 20.04, on a Huawei Matebook 13, with an NVIDIA GeForce MX250 graphics adapter. My goal is to connect 2 additional external monitors using the USB-C docking station Sandberg, which supports extending and mirror mode.
Ubuntu only recognizes one external monitor, and when I turn both on, I have the same image on both external screens. I would like to expand the desktop to use all 3 screens, one built-in and 2 external.
This is a screenshot of my display configuration:

This is my monitor setup:
How can I do this?
Since about two days, a pop-up message about "partial update" from Software Updater keeps appearing on my screen (Ubuntu 20.04). It says that "some updates cannot be installed" and prompts me to do a partial update. If I skip this, I get an usual Software Updater window, that lists several packages regarding to NVIDIA drivers, which are unselectable and only one package is selected (I enclose the screenshot below). I did not perform the update yet because I don't know why this situation occurs and whether it is safe to do the "partial update" as the program suggests (won't it break anything in my system?).
The unselectable NVIDIA packages are all version 390.143-0ubuntu0.20.04.1, while my currently installed version is 390.141-0ubuntu0.20.04.1.
Could anybody advise, why this situation occurs and what should I do?

I created the bootable usb drive with Rufus but PC will not boot to ubuntu.
It seems others have had this problem but not in the hast 5 years. Should i follow the grub commands given here?
Created a Bootable USB Drive to Install Ubuntu.. What next?
I have checked the BIOS and Secure Boot is disabled. Boot from USB is enabled.
Machine seems to boot from usb but just delivers the grub prompt. Any suggestions?
I have two displays. Main monitor through DVI works normal with Night Light. When I change to the HDMI display which is a OLED TV the image is ok except when I activate Night Light. The image turns green!
I've looked everywhere for this issue but couldn't find any solution. I've messed with the nvidia settings but with no success. Another issue is when I click Mirror Display it crashes and doesn't do anything.
Mirror Display crashes:

NVIDIA X Server Settings:
Ubuntu 19.10 Nvidia drivers 435 (tested 440 with the same result).
I am using a Lenovo ThinkPad W520. I recently updated from 14.04 to 18.04 (with a broken 16.04 in the middle where the UI completely stopped working -- low-graphics mode and had to be rescued.)
I now have a GUI back, but the resolution is 1600x900 rather than the expected 1920x1080.
On BIOS, display mode is set to discrete and Optimus is off.
I tried manually installing nvidia-driver-390 (don't know if that was the correct one, but it seemed to be what other w520s installed) -- also.

I tried following https://linoxide.com/linux-how-to/install-nvidia-drivers-ubuntu/ including suggested PPA, to no avail.
Update: I tried changing to 340 via the GUI, which caused it to instead go to nouveau, become corrupted, and be 480x480. After purging etc, I think I'm back to previous state.

I want to install a vnc-server on a Ubuntu 18.04 desktop (clean install). I've tried vino, tigervnc, tightvnc. For vino, I don't get the screensharing option in the settings. For tigervnc and tightvnc the installation proceeds, I create the configuration, but when I try to connect I get a grey screen with a cross cursor.
I've tried a VM (clean installation) with Ubuntu 19.04 desktop and vino-server, turned screen sharing on. When I tried to connect with Remmina from the host, I get a black screen, no cursor.
I'm lost here, have spent hours to get this working, thought this should be a straightforward thing to do.
How can I get screensharing via VNC to work?
SSH is running, UFW disabled.
I reinstalled Kubuntu and during my previous installation it didn't give me any problems. Now, when I pin a program (say chromium) to the taskbar right next to the "start" button the pinned icon disappears once I click to open chromium. The thing is I don't want it to disappear because I would sometimes like to quickly open a new window by reclicking the pinned chromium icon on my taskbar but unfortunately it disappears when I first click to open it. It reappears again once I close chromium again. Thank you!
I have n552vw laptop with i7 6700hq with the 960gt Nvidia driver. My Ubuntu 18.04 freezes on shutdown, restart and suspend, and I have to manually shutdown with the power button for turning off the computer. I tried https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia#Installation with no luck.

My laptop has Skylake CPU (Core i7 6700HQ) which doesn't support my Linux kernel and it gets stuck at the logo screen after installing Ubuntu. After struggling to resolve this issue I come up with adding Nouveau in grub configuration and I managed to login in Ubuntu eventually, and now I have this problem.
I'm trying to send my system to sleep using e.g.
rtcwake -v -m disk -s 60
and receive the following output
rtcwake: RTC wird als UTC interpretiert
UTC wird verwendet.
delta = 1
tzone = 0
tzname = UTC
systime = 1524206927, (UTC) Fri Apr 20 06:48:47 2018
rtctime = 1524206926, (UTC) Fri Apr 20 06:48:46 2018
Alarm 0, sys_time 1524206927, rtc_time 1524206926, Sekunden 60
rtcwake: wakeup from "disk" using /dev/rtc0 at Fri Apr 20 06:49:47 2018
suspend mode: disk; suspending system
rtcwake: write error
The system seems to start entering the suspend mode but returns back immediately. I'm running Ubuntu 16.04.4 LTS (GNU/Linux 4.13.0-38-generic x86_64). Are there any details, that would help to find the root cause of the problem (dmesg output, /var/log/syslog, ...)?
Thanks in advance,
Bernd
I have a QEMU/KVM virtual machine created with Virtual Machine Manager.
I would like to be able to copy text on the host and paste it into the guest, and the other way around too.
How can I share the clipboard between the host and the guest?
I'm trying to install mongodb on ubuntu 15.10. While following this - Install Mongo 3.2 on Ubuntu 15.10 - i got the following error message:
W: GPG error: http://repo.mongodb.org trusty/mongodb-org/3.2 Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY D68FA50FEA312927
So then I attempted to add the key like this:
me@devbox:/etc/test$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D68FA50FEA312927
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --homedir /tmp/tmp.CWnpUGSg5w --no-auto-check-trustdb --trust-model always --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyring /etc/apt/trusted.gpg.d/apt.postgresql.org.gpg --keyring /etc/apt/trusted.gpg.d/nginx_ubuntu_stable.gpg --keyring /etc/apt/trusted.gpg.d/webupd8team_ubuntu_java.gpg --keyserver keyserver.ubuntu.com --recv-keys D68FA50FEA312927
gpg: requesting key EA312927 from hkp server keyserver.ubuntu.com
gpg: keyserver timed out
gpg: keyserver receive failed: keyserver error
Not sure what else to try. I'm currently looking other posts here on this site to see if this has been addressed.
EDIT 1:
Based on this post: Can't add repo keys
I tried to run the command :
sudo gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys D68FA50FEA312927
and then retried:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys D68FA50FEA312927
But it's still failing.
Ok, I've tried to follow every example I could find but nothing is working. I need your help. One day an update came along and I lost my ethernet. A failed version upgrade eventually resulted in a reinstall of 15.04, then I upgraded to 15.10. In each version I have tried to download the current Realtek RTL8101E driver (I've also tried r8169 from the realtek site). I can get the r8101 module loaded but I can't even ping my router with the wired connection. Wireless IS running on the ath9k driver. Here is some detailed info:

I'm having trouble with Compiz since I upgraded to 12.04. I have an Nvidia graphics card (GeForce 9600M GT). In general Compiz works, but it has performance issues and rendering problems as in the following screenshot 1, that make usage impossible.
Click image to enlarge i.
According to my research the loose-binding option could help solving the problem. Unfortunately this is unavailable to me, as the Compiz Options in the Fusion Icon are grayed out.
Additionally the command-line argument --loose-binding for Compiz provokes an error that this option is unavailable. Same goes for the --indirect-binding option.
How to make those options available or solve the rendering problems in general?
This is what I'm seeing on my MacBook Pro 5,3 running Ubuntu 11.10 with gnome-shell and an Nvidia graphics card after I have resumed from suspend. The icons on the left-hand side was also blurred with noise as you can see on the text, but that seemed to have fixed itself after some time. Has anyone seen this kind of a behavior after a suspend command was given? Are there any known fixes?
