I have 2 displays connected to my laptop through a kvm switch. When booting up, ubuntu either doesn't detect the displays at all or only detecting one. The only way that I found to get ubuntu to properly detect the displays is sudo systemctl restart gdm so now every time I boot up my laptop the first thing I do is restart gdm. My question is, what happens in a gdm restart that doesn't happen (or happens in a different order maybe?) during booting up? And is there a way to do that without restarting gdm?

I'm using Ubuntu 24.04.4

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:

It started up just fine, but no WiFi at all. lspci said:

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 have an Ubuntu 22.04 LTS server that hasn't been restarted for more than 3 years. When I try to check the updates on the server using sudo apt-get update all the jammy repositories update without any issues, but when I run apt list --upgradable it's showing 0 updates. I thought it was a server restart issue, but after I restarted I still had the same issue. I tried to check the apt logs from /var/log/apt, but the folder isn't even there. What could be the possible cause of this?

I am incredibly new to Ubuntu so I know next to nothing about how it works. My issue is that after having my computer on for a bit the Wifi stops working and will will not connect to any other Wifi until after I restart my computer I have attempted to look online to try to find drivers but found nothing that works. I don't know what to do to fix this issue.

I have 5 machines running ubuntu 24.04. After upgrading some packages and rebooting, wakeonlan doesn't seem to work on any of my machines.

The machines are plugged in, and the ethernet port has lights blinking, so the network card should be awake.

I'm not sure whether the problems are due to upgrading packages or something else. I presume that this is a software problem that resulted from package upgrades changing a configuration file / variable somewhere.

Router is TP-Link AX3000. I rebooted and upgraded my router when trying to diagnose the issues, although I'm pretty confident the router is not an issue. Wake On Lan has worked before I upgraded the router firmware, and it has been working for at least a couple years prior to this week. However, there did seem to be an issue with receiving the magic packets when broadcasting to the local network (documented below). Not sure if this is a new issue, or is simply expected behavior.

I have tried to follow the guide here: https://wiki.archlinux.org/title/Wake-on-LAN. I'm out of ideas for what the problem is.

I can post additional files as necessary. Help is much appreciated!

Here is a sample from one of my machines:

The wakeonlan version I use is wakeonlan/noble,now 0.41-12.1 all [installed].

Ethernet should be nao3eth0.

I can receive the magic packets with the machine address. The broadcast address seems to fail, which seems odd. Prior to the upgrade, wakeonlan 34:17:eb:ce:b8:af was sufficient to wakeonlan remotely. I believe this is a separate issue, because wakeonlan is not working whether I specify the ip_address or not.

I was unable to provide all the variables for sysctl since it went over the character limit. I can provide further information upon request.

I believe the problems started occurring after the upgrade on last Friday, 2026-02-13.

I am new to Ubuntu which I have installed via Virtualbox on my iMac, Ubuntu 24.04.4 according to terminal. I am having a couple of problems with the Show Apps app on the tray.

First the captions on the various apps are not fully spelt out.

I see apps captioned "Blu..." "Bra..." etc.

Second question is : which particular apps I actually have ?

Now I know there is an app called "Ubuntu Software" with an icon of an orange briefcase with a large capital 'A' on it.

However I do NOT have this app.

This has to be the most annoying glitch ever :( I have been using whatever latest updates given for 24.04 for two years without problem. Today (2026-02-12) it offered and I allowed upgrade to 6.17.0-14-generic. Now I find that, at least in certain windows/applications, the mouse click/position in text windows is "off". Basically whenever I click or drag it is treating the "current line" as the line above where the I-beam text cursor is. It may relate to the position of the very top pixel of the I-beam, not sure. Essentially to do any text/programming work I am having to click at where I want in the line below the one I want. After a few hours of trying to do this consistently I cannot carry on. For me this breaks the whole ability to use Ubuntu at all.

I have discovered that, via grub, I can revert for now to the previous version, 6.14.0-37-generic. That shows no bad behaviour, mouse clicks/I-beam positioning is correct and what is always has been. But that option will disappear after the next update, and I may then be stuck with the new "bad" behaviour.

I don't know whether my environment is relevant. In case it is:

• I run under VirtualBox (from Windows 11 host). But that has not changed in a long time.

• I have an NVidia graphics card. But the VB uses "VMSVGA" as "Graphics Controller" and does not have "3D Acceleration" enabled, does that make the NVidia gfx card irrelevant?

• I run the GNOME desktop under Xorg, not Wayland. (I have tried to test Wayland but, for whatever reason, if I pick that from the desktop logon screen instead of Xorg it still seems to go into Xorg and I haven't got more time to investigate that.)

• My programming work is done in Qt Creator. Both its editor and any Qt application I run are affected. I am not sure about whether, say, gedit shows same or not and I don't know what other applications to look at. I'm thinking it is not a Qt issue but cannot be certain.

Does anyone know what sort of updates in 6.17 might affect this area? E.g. I think I saw it updated "mesa" stuff, could that be implicated?

If anyone has any thoughts or suggestions I am listening. Otherwise if anyone else experiences similar please let me know here. I have no idea whether I am somehow alone in this or whether it will show up for other people.

UPDATE: It is possible this is, somehow, a Qt/Qt application issue. Which will obviously reduce the number of other people likely to experience it. It is hard to tell/be sure, but trying other text editors (with mouse) like gedit or PyCharm I am thinking they are not "off" under new kernel. I cannot imagine how a change to kernel would only affect Qt applications in this fashion, but who knows....

I was trying to install davinci resolve and when I tried to run it, it gave me a bunch of repositories to install. I got libasound2 and when I install that, my screen went black and on restart I was in terminal. I ran sudo apt-get install --reinstall ubuntu-desktop and after that nothing is working. I try to use vlc media player and it doesnt work, I try to open settings and it doesnt work. Nautilus broke and I tried all the fixes on the internet to no success so I installed nemo. I havent checked what else isnt working but I would greatly appreciate some help.

Hello Ubuntu Community,

I recently installed Ubuntu 24.04 on my Lenovo ThinkPad Carbon X1 Gen 12.I'm facing an issue with the trackpad not working. I selected the full installation during the setup, the system seems to have install the necessary drivers for the trackpad as It worked for two sessions after that it suddenly stopped working.I was able to see trackpad setting in 'Setting'. Here's what I have tried so far:

1. System Update:

sudo apt update
sudo apt upgrade
sudo apt dist-upgrade

2. Installed Synaptics and Libinput Drivers:

sudo apt install xserver-xorg-input-synaptics xserver-xorg-input-libinput

3. Checked Touchpad Settings: Verified that the touchpad is not enabled in Settings > Mouse & Touchpad. Only setting for mouse are enabled.

4. Modified GRUB Configuration: Edited /etc/default/grub to include:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux i8042.reset"

Updated GRUB and rebooted:

sudo update-grub
sudo reboot

Unfortunately, none of these steps have resolved the issue. The trackpad still does not respond.

System Information:

• Model: Lenovo ThinkPad Carbon X1 Gen 12
• OS: Ubuntu 24.04
• Kernel Version: 6.8.0-35-generic

Has anyone experienced a similar issue or have any additional suggestions on how to fix this? Any help would be greatly appreciated.

Thanks in advance!

I have a very interesting question. My video card is an nvidia gt 730 and it supports 3 monitors. One VGA, 1 DVI and 1 HDMI. I have 2 monitors and both VGA. My second monitor's VGA cable at my computer is plugged in with an DVI changer. I keep having this Unknown display.

I was just wondering if I could install Ubuntu 22.10 in my Android tablet? Will it works exactly like it does in my laptop? I have 6gb of ram in the tablet and a decent mid range processor? Will it be good enough to do all the basics task?

After installing a fresh copy of Ubuntu 22.04 I attempted to enable Remote Desktop:

I then went to another workstation (tried both Windows and macOS with the Microsoft RDC and with Jump Desktop) and tried to connect. When it failed without any significant details I jumped into /var/log/syslog on Ubuntu and found the following:

Jul 21 02:04:16 HOSTNAME gnome-remote-de[3006]: Couldn't retrieve RDP username: Credentials not set
Jul 21 02:04:55 HOSTNAME gnome-remote-de[3006]: message repeated 6 times: [ Couldn't retrieve RDP username: Credentials not set]

I then opened the system Settings → Sharing → Remote Desktop and was confronted with they keychain login prompt. After authenticating I attempted to again connect via RDP with the previous RDCs.

As I watched syslog, I observed the following results: Jump Desktop:

This is using the "User Name" and "Password" generated in the above screenshot.

Aside from what seems to be an obvious bug in the beginning wherein it's necessary to authenticate before FreeRDP even tries to connect, clearly there are other issues at play beyond that.

Anyone aware of what may be going on and failing here?

I've been using Ubuntu 20.04 for quite some time now. I also have the NVIDIA Quadro P600. After seeing the same error over and over, I decided to investigate the error. After some time with the computer on - the menus (when I try to shutdown, restart, etc.) are gone missing. I can hover over them, but I can't see the text.

I assumed it's the GPU drivers (after all - it's visual). Then I decided to try and update. I did the sudo apt update and sudo apt upgrade just to be on the safe side.

Then tried to update using this command:

'sudo apt install nvidia-driver-510 nvidia-dkms-510

...and I've been getting this over and over:

I don't know what to do. I've been trying to update via system update (GUI version) I've been getting some huge errors.

I downloaded the zipped folder for the ToolBox app from JetBrains' official site. After extracting the folder, I clicked multiple times on the ToolBox executable app, but nothing happened on the screen. On searching a bit more deeply, I found that no app supported running such a file!

Please HELP...

I'm new to Linux and I use Ubuntu 20.04.4 LTS. I need to switch from integrated to dedicated GPU, or be able to launch some programs (for example, Steam) with nvidia GPU. I had this problem previously and I solved it using xrandr --setprovideroffloadsink . It worked until recently (I think until Nvidia issued a new 510 driver). Now I can't use the above method to resolve my problem, because the output of xrandr --listproviders is:

Providers: number : 1
Provider 0: id: 0x43 cap: 0x9, Source Output, Sink Offload crtcs: 3 outputs: 1 associated providers: 0 name:modesetting

so I can't switch between them.

I tried to:

1. Purge the Nvidia drivers and install the new one as in this (https://gist.github.com/espoirMur/65cec3d67e0a96e270860c9c276ab9fa) tutorial,
2. Used sudo prime-select nvidia
3. Changed profile to high performance in NVIDIA X Server Settings,
4. DRI-PRIME = 1 command.

While trying to resolve the problem encountered that command:

$ nvidia-smi
*"NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running."*
Search on this problem gave the tutorial which was similar to point 1 of the above steps (it didn't work as well, the output is the same).

Screenshot of the system information:

I recently installed steam on my Kubuntu 20.04 LTS machine using the .deb from their website, and on launch, it opens a terminal asking me to install other Nvidia drivers.

I run Nvidia-driver-470 proprietary drivers on my 1660ti. (also tried nvidia-driver-495)

Other specs in my PC are:

• Core i7 8700
• 16GB RAM

The terminal shows this output when Steam opens at startup:

Steam needs to install these additional packages:

I press Enter after the 1st prompt, and it asks for the root password, then prints out what is seen in picture 1. After the second prompt pressing Enter closes the terminal window and opens steam immediately. It does this for every startup.

I have tried:

sudo apt-get remove --purge steam steam-launcher
rm -rf ~/.local/share/Steam && rm -rf ~/.steam
sudo apt clean && sudo apt -f install

Installing steam after that fixes nothing.

The worst of all is, most of the games don't even work. They either freeze or crash at startup or midway. And it is not only the games that use Proton (i use 6.3), games like Portal 2, which run natively I believe also crash.

I have googled and found no solutions so please help.

I just installed Kubuntu 20.04 and I have an Nvidia GTX 1050TI. Now I installed Ubuntu Studio 20.04 a year ago, and I was able to use the "Software Sources" application to install proprietary drivers for my graphics card without any issues, but now that I just switched Kubuntu 20.04 (dame computer, Fresh Install, No files from Ubuntu Studio's home folder were preserved), All the options in the Additional Drivers section of Software Sources are greyed out, and the only selected option is "Continue using a manually installed driver". Which is weird, since I didn't manually install any drivers.

How do I use a proprietary driver now (Like nvidia-390)?

Additional Drivers:

I have dual booted both the Windows 10 and Ubuntu 20.04 in a 512GB SSD. I have noticed that while using Ubuntu fan speed is very high & system gets overheated even when only a few applications are running, but while using Windows I did not notice much heat or any of these issues. Battery usage is much lower in Windows compared to Ubuntu.

My Dell XPS 13 7390 running Ubuntu 20.10 (kernel 5.8.0-28-generic) regularly freezes up entirely. This sometimes happens multiple times a day, sometimes every few days - I am unable to see a pattern here, nor figure out which apps or actions seem to provoke it.

When it happens:

1. The UI and keyboard freezes completely (including the clock in the GNOME menu bar), with only the mouse still being operable. I cannot click or interact with anything.
2. Alt + F2 does not react. Thus, I can neither xkill nor run a terminal from there.
3. Ctrl + Alt + F1 to start a new session also does not work.

I can only REISUB the computer to get it to restart, and I lose any unsaved work.

Upon restarting, having taken note of the time of the hang each time (the GNOME clock freezes at that exact time), journalctl delivers:

I cannot find any meaningful help online.

Helpful information may also include:

• It's a dual boot system with Windows 10.
• I run with fractional scaling enabled (dconf org/gnome/mutter/x11/experimental-features set to [scale-monitor-framebuffer, x11-randr-fractional-scaling]).

As I was often using JetBrains IDEs when the freezes happened, I ran across this YouTrack issue, detailing a downgrade of mutter would solve a similar issue on Ubuntu 19.10 - however, I don't know how to adapt this to my specific issue.

I recently switched from Windows to Ubuntu 20.04. Whenever I play videos it stutters. This happens with both locally stored videos and online streaming sites like YouTube, Twitch, etc. (on all browsers), there is no lag in audio.

I installed latest Nvidia driver and followed this solution to get rid of the screen tearing issue, but still the screen stuttering issue persisted. I tried almost all of the solutions from different forums. I even tried rolling back to older version of Nvidia drivers, but none of them worked for me.

Results of neofetch:

I installed Ubuntu 20.04 on my Amd Ryzen 5 1600 / Nvidia Gtx 1070 two weeks ago but Ubuntu completely freezes from time to time.

Keyboard and screen stop working completely, mouse sometimes is able to keep moving. I've tried using the magic SysRq key but didn't work. Also tried alt+F1 but didn't get any response from the system either. Basically I'm left with pressing the power button in order to restart.

I'm suspecting Nvidia but I don't know how to verify.

nvidia-smi shows driver version 440.100.

Then I have tried the $ export GDK_NATIVE_WINDOWS=true , $ export GDK_NATIVE_WINDOWS=1, then $ export LD_LIBRARY_PATH=/usr/lib/jni , then $ export PATH=./bin:$PATH .. please to know the steps to open UIautomatorviewer in the Ubuntu 18.04. This is for the Appium + android studio mobile app testing.

I have Ubuntu 19.04 on an ASUS Zenbook 13. I was running the system with nomodeset in the grub settings.

I tried to install a new Nvidia 418 driver by using the suggested path (set a MOK password for safe booting system). After doing that, the system is stuck at this point for 30 minutes.

I was using Windows 10. Then I installed Ubuntu 18.04 LTS as multiboot. Grub2 replaced Windows bootloader. I wanted Windows bootloader, so I installed EasyBCD 2.3 on my Windows 10. I created a new Linux entry on it. When I booted I had two entries, but instead of booting to Ubuntu it booted to "grub4dos".

I used the Boot-Repair tool via live USB. It reinstalled grub2, but now I have two bootloaders. grub2 loads first. Then, when I select Windows 10 from it, Windows bootloader loaded up. I have to select Windows from it to boot into Windows 10. As I use Windows 10, regularly. I have to go through two bootloaders to get to my Windows 10.

I like to have either grub2 or Windows bootloader which boots both OSs with single click.

I use a laptop with a single HDD.

I had tried different options on EasyBCD but every time I end up using my Boot-Repair live USB to reinstall grub2.

I bought recently a computer and installed ubuntu but get this error when ubuntu is booting

[   91.167119] pcieport 0000:00:1c.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=00e0(Receiver ID)

What is it?

is It bad?

How to fix it?

I have recently installed Ubuntu 16.04 beside Windows 7.
I use TP-Link TL-WN821n.
Ubuntu normally installed,
seems that USB stick driver was installed automatically.
but the internet connection is very slow (in Windows is normal).
I run connection speed test in Ubuntu it shows:

• 0.90 MB/s - Download
• 1.00 MB/s - Upload

While my connection is 30MB/s Download, 3.0MB/s Upload (speed test in windows shows that).
i tried to search about how to fix the problem, run more than 7 solution and nothing got fixed.
Can anybody help me with that?
Regards,

I know this was already answered by Evan T at Unable to connect to wireless network following upgrade to 15.04, however, I am having some trouble doing all the indicated steps: after sudo gedit /etc/modprobe.d/iwlwifi.conf, I receive the message:

(gedit: 1627): Gtk-Warning **: Calling Inhibit failed: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files

After typing "sudo rmmod iwlmvm iwlwifi" I received another two error messages:

rmmod: ERROR: Module iwlmvm is not currently loaded
rmmod: ERROR: Module iwlwifi is not currently loaded

Also, I don't know if this is related to the wireless internet problem, but the laptop doesn't recognise the mouse (in any USB port, the mouse is wireless). Thank you!

When I try to attach an external monitor to my laptop, the windows are stretched oddly horizontally and the click offset is off. The Nvidia settings also doesn't seem to show the built-in laptop display, but the Ubuntu display settings does.

If I add a third monitor, the two external monitors work fine with no stretching or misclicking, but the laptop monitor is blank. I can't drag windows to it, but I can move the mouse there.

If I use any monitor by itself it works fine.

This is a fresh (with the exception of crashplan) install of 14.04.1 LTS x86_64, using the latest tested driver in additional drivers (nvidia-331.113 and nvidia-prime). It's on a Dell M6800 with a Quadro K4100M. Displays are connected via display port from a dock.

^{Click image to enlarge it.}

Purging Nvidia drivers and using Nouveau works fine, but it runs slow.

It is related to Nvidia Optimus. Turning that off in the BIOS fixes the issue, though I'd like to be able to switch to my integrated graphics in the future.

Is there a way to change the partition format from FAT32 to NTFS without losing data in it?

For now I am aware of one method: split partition in two, set the new partition format to NTFS, copy data to it, then delete the old partition and add its space to the new one. One fault with this method is simple: it can't be done if more than a half of the current partition is already used.

So I'm looking for a solution that wouldn't delete my data, and just change the partition format from FAT32 to NTFS. Is something like that possible or not?

It first started when I deleted my partition that had Ubuntu 12.04 on it. Little did I realize at the time that it would destroy all the resources of grub on it, and subsequently prevent me booting into my hibernated Windows 7, so I made a 12.10 Ubuntu live USB and reinstalled Windows bootloader.

When I rebooted it gave me a bootloader error saying I that it could not find the resources to boot from, so I went back to my live USB, installed Boot-Repair and tried to repair the mbr. It didn't work though. Here is the URL that Boot-Repair gave me if I was in trouble: http://paste.ubuntu.com/1328309

I have a laptop that has no CD drive, so I cannot use the Windows installation disk. Also I don't own the disk.
