Each time my computer goes to sleep the windows change their size. Some time, they appear bigger, but most of the time, they are smaller. It's hard to tell by how much. Maybe a "titlebar" smaller/larger. It also changes the width in a pretty much similar amount.

I already experienced that issue in Ubuntu 18.04 (I'm on Ubuntu 24.04 now) when using VirtualBox. But now that happens in my regular installation. I'm not too sure what I could possibly try to avoid that issue. It makes no sense to me that the windowing system would just randomly resize windows under my feet.

Have you experience a similar situation? Did you have a solution to the problem?

I’m experiencing an issue where the Steam version of Terminator: Dark Fate – Defiance suddenly stopped launching, despite having previously working flawlessly.

When I click “Play” on the Slitherine game launcher, the game immediately crashes without opening.

System details:

• OS: Latest Kubuntu release
• GPU: AMD RX 6700 XT
• Driver: Mesa (RADV Vulkan driver)
• Session: X11
• Proton: GE-Proton 10-10

Troubleshooting steps already attempted (with chatgpt):

• Verified integrity of game files in Steam.
• Reinstalled the game.
• Completely removed Proton prefixes and remaining game files before reinstalling.
• Rebuilt the prefix from scratch.
• Cleared caches.
• Tested multiple Proton versions (including the one that previously worked).
• Installed/checked common dependencies via terminal.
• Reviewed logs generated by the game.

Key observation:

The GOG version of the same game runs correctly when launched through Lutris, using the same Proton version.

Relevant log output (from the game log):

Failed to load component [".../bin/game.dll"]: can't LoadLibrary()  
FATAL. Exception: UNKNOWN

Given that:

• The game runs fine via Lutris (GOG version).
• The same Proton version is being used.
• The issue only affects the Steam version

What could cause the Steam version to fail to launch while the GOG version works correctly?

Are there Steam-specific factors (such as runtime differences, environment variables, or Proton integration details) that could explain this behavior?

I’m partly asking out of curiosity as well, since I can’t reconcile how the same game and Proton version behave differently between Steam and Lutris.

Im trying to type curly or square brackets but I can't find how to do it, my usual way in MacOs is (PT-PT layout):

Square brackets:

• [ → Option + 8

• ] → Option + 9

Curly brackets:

• { → Shift + Option + 8

• } → Shift + Option + 9

When I try this in Ubuntu nothing is printed, I would really appreciate if someone could help me please.

I managed to solve another error with wodim. I got a bit farther with Brasero, but I can't seem to find anything on my specific issue. I've had no problem ripping movies from DVDs on the same optical drive.

linux noob here. Recently installed cinammon mint Wilma on my dell laptop and on bootup I've been getting this error message. I don't really have anything else installed on here other than a few normal apps like firefox, etc.

The kernel version is 6.17.0-19. The update aborted with Package failed to install. What package? I can find no errors in the /var/log/apt logs, and sudo apt update says all packages are up to date. The laptop is brain damaged. The network interface is gone - no configuration options are displayed. The internal mouse pad is non-operational. I have to plug in a USB mouse. The external display no longer works. The kernel modules for VirtualBox 7.2.6 fail to load. It seems like the only app that's still working is the terminal.

Thanx for the response. Seems my initial writing got lost somehow. It was probably me. 😊

My NAS is a Thecus N5200 pro I believe. What happened is that it was unstable for a few days, before it got inaccessible.

I discovered that disk 3 of 5, was dead, no movement when tested with icy box docking.

Disk, 1, 2, 4 and 5, are still ok, and I have made an image file of each.

The Thecus N5200 reports "no raid" in startup dialogue, and no raid is found when entering NAS through ip address.

So the raid setup is lost. I hope to find the raid setup in the remaining 4 disks.

Unfortunately, I am not sure what raid was setup on the Thecus before the crash. I guess it has to be the one where only one disc can be missing before data loss. But I am not sure.

I hope to reassemble raid from metadata on the remaining disks, or by other means extract any files possible.

The hdd's with the .img copies, are now mounted in another computer, running Ubuntu.

I have come to understand that there is a lot of options in Ubuntu to diagnose, reassemble and extract data. But I am uncertain what steps to take, and how.

I understand that much can be done with Ubuntu, and maybe some is better done with testdisk.

I just need someone to hold my hand as I am blinded walking through the dark forest. 😎

I am a seasoned windows user, but a greenhorn on UBUNTU, but I have faith that I might be able to learn. I have already come this far. :-)

Thanxalot.

The web application is developed in Python and runs on Ubuntu. The instance, which has 2 GB of memory, needs to be restarted every 8–10 days, even when there is no user activity.

Thank you!

Every time I open Steam from the dock or the icon, my entire PC instantly crashes and restarts. However, opening Steam from terminal seems to work fine. This only started happening a few days ago; I have been using Steam as normal for months before then.

What might be causing this problem? What are some steps for troubleshooting?

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 24.04.4 LTS
Release:    24.04
Codename:   noble

This is an active issue and incident as of March 21, 2026.

I am seeing a question mark on my networking in Desktop and Network Manager but my network is functioning with internet. Sometimes I am told to 'sign in' to my network even though I am already connected. (Or in some cases, people are being asked to sign into wifi when they don't have wifi)

Why is this?

For security reasons, Firefox and other browsers block local file: URLs like file:///tmp/foo.html that are linked from external web pages. That makes sense to me. But it also blocks access to file: URLs like file:///tmp/foo.html when I manually paste them into the address bar, or link them from another local file such as file:///tmp/bar.html , which would not be a security risk. I also cannot right-click on a local HTML file and open it in Firefox to preview it, which is ridiculously frustrating. Furthermore -- and contradictorily -- Firefox allows me to set my home page to file:///tmp/foo.html , but it does not allow me to set my "new tab" page to file:///tmp/foo.html . An extension exists to address the "new tab" problem, but it does not address the rest of these restrictions.

How can I enable Firefox to display file: URLs that are referenced only from other file: URLs, typed into the address bar, opened locally by right-click from the file manager, or specified as my "new tab" page?

This page says I can disable that security check for specific sites, but I do not know how to specify my local file system as a "site".

I'm looking for a reliable WhatsApp client that works well on Ubuntu 24.04 LTS. Ideally, the client should have:

• Desktop notifications that integrate properly with Ubuntu’s notification system
• Autostart on login, so I don't miss any messages or notifications
• (Optional but preferred): Support for video and/or voice calls

How to set this up?

I'm trying to build a docker image from ros:humble-ros-base, on a Raspberry Pi4 with Ubuntu 22.04 installed.

The first lines of the Dockerfile are

FROM ros:humble-ros-base
RUN apt update

I get the error

ERROR: failed to solve: process "/bin/bash -c apt update -y" did not complete successfully: exit code: 100

after reading all package lists successfully.

Tried to uninstall and reinstall docker completely, and also tried with other debian bases images, it always fails at the same point.

Also tried running

docker run --privileged --rm tonistiigi/binfmt --install all

, as suggested in another related topic, but it didn't solve the problem.

The Dockerfile builds successfully on other platforms (a computer under ubuntu 22.04 and one under 20.04).

Would anyone have an idea on what could the problem be ?

Thanks

Very big newbie here, spent the last 90 minutes trying to troubleshoot audio. Here's the Narrative of what happened: I was having trouble connecting my bluetooth headset to Xubuntu. The problem was that the connection would hang and do nothing. I installed Pipewire and replaced PulseAudio, now I could connect my headset, but it would instantly disconnect. Then I installed Wireplumber and everything worked. I connected my headset and was happily listening to audio.

Then I logged out, and when I logged back in, my headset connected automatically, but no longer played audio. Instead I was hearing a crackling/popping noise. Funky. I opened up Pavucontrol and messed around with stuff. Turns out, if I switch to HSP/HFP instead of A2DP everything works (albeit garbage audio quality). And to be clear, both profiles are available in Pavucontrol and the device can switch between both. The A2DP profiles were working when I was in the session where I first installed PipeWire and Wireplumber.

Here's what grinds my gears: it worked perfectly when I was still logged into the session where I initially installed Pipewire and Wireplumber. After logging out and logging back in, this issue began.

Any help would be appreciated. I've already searched through this forum and others to find a solution.

im setting a server with Ubuntu 22.04 and i have been instaling Ubuntu several times. At first, Network Manager worked great and displayed all the networks, but now nmtui doesnt show anything, and nmcli shows that everything is unmanaged or disconnected. Any ideas? By the way, I also tried a Virtual Maachine but it enda in the same way

Whilst there have been older questions asked, it might be worth putting this in for Jammy 22.04

running from command line I got a funky error message... which had bug history for previous Ubuntu versions. and running sudo gnome-control-center got an error message.

this is a new and clean install.

so I was having issues with domain resolution with WSL whenever I use the VPN. I would get this:

ping: google.com: Temporary failure in name resolution

I tried following instructions from these answers Temporary Failure in name resolution on WSL

Specifically from this part:

1. Inside WSL2, create or append file: /etc/wsl.conf

2. Put the following lines in the file in order to ensure the your DNS changes do not get blown away

   echo "[network]" | sudo tee /etc/wsl.conf
   echo "generateResolvConf = false" | sudo tee -a /etc/wsl.conf
   

3. In a cmd window, run wsl --shutdown

4. Start WSL2

5. Run the following inside WSL2

   sudo rm -rf /etc/resolv.conf
   sudo cat << EOF > /etc/resolv.conf
   search [yourbase.domain.local]
   nameserver 8.8.8.8
   nameserver 1.1.1.1
   EOF
   

However, I cannot seem to be able to edit the file /etc/resolv.conf as I would get zsh: permission denied: /etc/resolv.conf

I also don't know what it means [yourbase.domain.local] or with what I should be replacing it. I already messed up my domain resolution, and now I get the first error every time, even when my laptop is not connected to the VPN. I really need to know how to fix the config files that I modified

Edit: using muru's suggestion from the comments, I was able to fix the domain resolution with the command

sudo tee /etc/resolv.conf <<EOF

However, I'd like to know if there is a solution for this error when I connect to a VPN. Since none of the solutions from the mentioned link didn't work for me.

I have just bought a new Lenovo Legion 5-15ARH05.

The touchpad itself works in windows and when I disable hid-multitouch in Linux I can get it working, but the cursor is moving in absolute coordinates so it's unusable.

If someone has an idea how to solve it I would really appreciate it. On the internet I found some threads describing a similar problem, but they don't talk about how the clicking is working and other stuff. One lead might be that supposedly from kernel 5.4 it stopped working, however, I cannot test it.

I am not able to boot 5.3. But I booted 5.0 and it did not work.

Well, the title says it. I have a Lenovo yoga 500, recently updated to 20.04. When I was on 19.10, the keyboard used to show automatically when I touch a textbox. However, now it won't open, unless I do it manually via the Universal Access menu. I'll be happy If someone can help me.

I'm on Ubuntu 18.04 on a Dell 3442 laptop. I'm trying to make an audio interface - Tascam US-800 - to work. I've done it before years ago, same hardware, can't remember what Ubuntu Studio version.. Now I'm getting this kind of error. I just dumped Windows out of my system, tried first Ubuntu Studio 19.10 and now Ubuntu 18.04, with no success. The same device was running Ok on Windows 10 a few days ago. Tried again in my wife's laptop with Windows - working fine.

I'm getting this error in dmesg:

I've tried several things like usbcore.autosuspend=-1, iommu=soft, the "unplug everything for 3 min" trick, ... plugged/unplugged in every USB hub, all of them work fine with other devices like optical mouse. I'm googling everything related to this problem with no success... I don't want to give up, because as I said it worked before... and going back to Windows is a big turn off for me.

EDIT1: I forgot to say this is a device not officially supported by Ubuntu or Tascam, which has discontinued the product. There are official drivers for Windows and Mac. Please, point me to the way of hacking those drivers!

EDIT2: So I did a clean install of Ubuntu Studio 19.10, this time letting it erase everything from disk and partition it's own way. Now I get only the second error, cannot get ctl value. That's a start.. I'm going to research more on the subject. Any help would be immensely appreciated!

I am on an university network, so naturally I use a proxy. I have set the proxy appropriately in /etc/environment, but no matter what I do there's always this error:

https://api.snapcraft.io/v2/snaps/refresh: proxyconnect tcp: tls:
   oversized record received with length 20527

I have restarted, reset, removed and reinstalled snap, but time and again there's no solution. The past solutions are no help, and anything I do doesn't change the error messages. Is the Snap Store really unusable in a proxy?

I changed a few things, and now I get a different error:

https://api.snapcraft.io/v2/snaps/refresh: Proxy Authentication Required

This is really frustrating because wherever I use proxy, I use the format:

username:password@host:port

whether it is /etc/environment, ~/.bashrc or /etc/apt/apt.conf. I have no problem in connectivity via apt, and wget works fine too. It's snap that puzzles me.

I am getting this error when I want to import tensorflow-gpu on Ubuntu 16.04.

I have installed CUDA 9.1 properly, cudNN 7.1 properly and tested both without facing any problem. (using python 3.5 2.)

I have used pip3 in either ways (with several tensorflow versions): i tried:

#for tensoflow 1.4
pip3 install tensorflow-gpu==1.4
# for tensorflow 1.8 from source
pip3 install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.8.0rc1-cp35-cp35m-linux_x86_64.whl

I have tried to install several versions of tensorflow-gpu , 1.4, 1.5 , 1.8 ,1.9. still getting the same error, when running

import tensorflow as tf 

ImportError: libcublas.so.9.0: cannot open shared object file: No such file or directory

Is there any way to get rid of this? or it is just installing cuda 9.0 ( which will be the pain as it took a week for me to install the cuda 9.1 due to problems of nvidia and Ubuntu !)

I also installed libcupti (required) and Bazel (required). from this page: http://www.python36.com/install-tensorflow141-gpu/2/

moreover, i have installed the same setup on windows (tensorflow 1.8 , cuda 9.1) without any problem.

About a week ago Windows 10 ran its automatic updates and after that I'm unable to boot to ubuntu the way I was doing it (pressing f12 and manually selecting Ubuntu partition). Now it takes me to a black screen saying Unknown Filesystem grub rescue when I try to access it that way.

The partition isn't wiped out and Ubuntu works just fine, but I have to enter a few commands as shown in this video(Non-English) to access it. Would anyone mind helping me to "revert" whatever windows did so I can keep booting to ubuntu manually when I want to with f12 key?

Additional info - I asked this question on Reddit and I was asked

"what is the output of 'fdisk -l' in the terminal?"

This is what shows up:

I am using an ASUS N53J that is currently using MBR boot. I have enabled UEFI booting in the bios can can seem to boot USB drives that have been configured with gpt tables. Though I have not figured out how to make use of a dedicated EFI boot partition on the USB drive as yet.

Separately I have connected a second hdd to the laptop via the external SATA connection, created a gpt partition table, esp boot partition, and the filesystem and swap partitions.

When I run grub-mkconfig on the internal hdd, it finds the new linux image on the external hdd. I can boot to that external image and confirm that the esp boot partition gets mounted at /boot/efi, so it appears that I should be able to configure grub2. However, if I run grub-mkconfig when executing from the external drive, its own image does not get found, only the linux and windows images on the internal drive.

I also cannot get efibootmgr to run. The tutorials I have read either are not clear on both the how and the why so I can troubleshoot myself or use commands that I cannot find in the packages I think they are using. Does anyone have a good pointer on how to configure the disk before I install it as the primary boot disk?

Thanks.

Update 2015-12-30 I have progressed to making a USB drive that will at least boot into grub rescue. I do not know why grub won't run from this drive but it at least allows me to manually boot to my target OS. Since I have now booted via a UEFI boot efibootmgr is available.

I performed a new grub-install targeting the esp partition mounted at /boot/efi. This completed without errors. However, when I select the target system for booting the firmware loader stops at a blank screen. This occurs whether the disk is connected via ESATA or has been moved to be the primary disk in the machine.

the output of efibootmgr -v is:

The desired target is Boot0005. Boot0002 is an experiment copying grubx64.efi to /boot/efi/bootx64.efi. Both Boot0002 and Boot0005 behave similarly.

Boot0003 (grub) is the USB drive and the only means to boot, though it only starts in grub rescue.

Any ideas where I should explore or what additional information may assist diagnosis?

More progress:

grub rescue> set  
prefix=(hd0,2)/boot/grub  ... This is the fat32-formatted esp boot partition  

grub rescue>ls (hd0,2)/  
unknown filesystem      ... or similar words to that effect

grub rescue>set prefix=(hd0,1)/boot/grub  ... ext4-formatted partition
grub rescue> insmod fat
grub rescue>ls (hd0,2)/
                    .... the directory is now read

setting the root to the target boot system and the prefix to the /boot/grub directory of that target system I can insmod linux search config file and normal. If normal does not start the boot option page the following will:

grub rescue>configfile /boot/grub/grub.cfg

I can eventually get the target to boot from the menu.

My synopsis is that grubx64.efi on the USB drive is not configured with the necessary modules for the boot method being used.

While efi-booted into my target filesystem I created a new USB drive, also with a gpt partition table, this time with esp boot as partition 1. I only mention that to assist with reading the bios boot table presented later.

mounting USB partition 2 to an appropriate node:

mkdir -p /boot/efi

mount (USB partition 1) to (USB partition 2)/boot/efi

grub-install --target=x86_64-efi --efi-directory=(USB partition 2)/boot/efi --removable

generates EFI/BOOT/BOOTx64.EFI. The UEFI: Sandisk entry in the bios boot table is the means to boot via this loader

grub-install --target=x86_64-efi --efi-directory=(USB partition2)/boot/efi --bootloader-id=USBboot

generates EFI/USBboot/grubx64.efi. The USBboot entry is also written int the bios boot table

cmp -v BOOT/BOOTx64.EFI USBboot/grubx64.efi yields no differences
either boot option now boots directly to the target filesystem without displaying any grub boot menu. Since the USB drive does not have a /boot/grub directory or a grub.cfg, grubx64.exe must be configured to search for this directory on the target rather than USB.

I still have not figured out how to even get to grub rescue without booting from the external USB drive. Is seems as though I have two problems:

1. I don't fully understand how to configure grub for its intended use, how to make sure necessary modules are built in and the prefix is properly set.
2. I either do not have the bios on the ASUS N53J properly configured or it is not accepting the hard disk configuration as a valid boot configuration.

Any other ideas? I now this is getting rather long. How can I document this to be more readable?

Status Update

Browsing on the web I have discovered grub-mkimage. I have not started working with this and will report progress once I have done so and can either understand the results or can pose a new question about it.

Which one is the most lightware video player ?

I watch usually normal videos, with not so high resolution...

Referring to the hardware resources used tell me please do you recommend me a video player which comes with the most common codecs included, or is it possible to use a fast way in Linux to download/install the video and audio codec that I need for the video which I am trying to watch?

If this is possible how can I find in Linux the video codec which I need to see the video?

One of the most important option included would be to search and download subtitles for the video which I am watching to (would be better to search on more subtitles websites).

Thank you.

In my opinion it is not a duplicate of Programs to download subtitles for videos because the question is about a light video player with the subtitles download feature included too.

I'm behind a corporate proxy, and we have Windows PCs with root ca certs pre-installed so SSL works with the proxy. Within my PC, I'm spinning up Linux VMs for testing, and so I have a need to get those certs installed within the VM so I can hit whatever SSL URL I need (github cloning etc). I've tried a few methods to export the certs from Windows and import them into Ubuntu, but as of yet I am unable to access SSL from within the VM.

This answer gave me the best idea for what format to export the cert in from Windows (base-64 .cer). After I export the .cer files and copy them into place in the VM, I rename them with .crt extensions.

This answer best sums up what I'm trying in the VM.

After I add the certs to the usr/share/ca-certificates directory and run update-ca-certificates the certs do get symlinked into /etc/ssl/certs but still no SSL traffic.

This is on a Windows 7 host, Ubuntu 12.04 guest.

I have a Dell 3750 Vostro laptop running Ubuntu 14.04 LTS with an NVIDIA GT 525M graphics card. I recently purchased an external monitor, which has both HDMI and VGA input. The VGA input works perfectly, however the HDMI says "No Signal Detected". I would love to use the HDMI connection to this monitor - but I have had no success whatsoever getting it to work.

I have installed Bumblebee, and I have also run sudo apt-get install nvidia-current. Neither of these had any effect on the HDMI output. Is there anything else I can try? Here is the output from xrandr:

I notice that there is no HDMI entry - is this perhaps part of the problem? Thanks for any help! :)

I have a problem. I have a lapop with an Nvidia card and an Intel one

While I am using the Nvidia one (using PRIME profiles) I cannot change the display resolution using xrandr in terminal. All it does is that the display goes black for a second then back to the native resolution. However, when using the Intel card it works without an issue.

This is an issue for me because I play a lot of old games using Wine and most of them have very low resolutions and so, when using Nvidia, they are displayed on the top-left part of the screen, instead of being stretched to fill the whole screen like they do when using the Intel card (because the screen resolution will change to that of the game)

I also noticed that changing the resolution through System Settings -> Display works on both cards but it dosen't help much...

If I could get xrandr to change the resolution on the Nvidia card then those games will work or if not then I could make a script to do it when the game launches and change back to the native one when it's closed.

My OS is Ubuntu 14.04 x64 and I use the up-to-date Nvidia proprietary stable drivers. It's a laptop if that matters

EDIT: I just noticed that if I connect an external monitor (VGA1) I can change the resolution just fine on either monitor... and the game now runs fullscreen... but as soon as I disconnect it the issue comes back :(

I removed the HDD from a Toshiba Computer I bought today and installed a 250GB SSD. After installing it, I immediately installed Ubuntu 14.04 on it from a USB drive. Everything went fine during installation, but when I restarted I got the message

Reboot and select proper Boot device or Insert Boot Media in selected Boot Device and press a key.

That message came up after a nano-second screen that says Checking Media Presence and then No Media Present.

When I reboot using the USB stick, I can see the SSD drive and it has the OS written on it and it looks like it's been partitioned correctly.

Can someone please tell me what I need to do to get my computer to boot up?

• I read something about how the Secure boot and CSM or UEFI might be a factor, but I'm not experienced enough with new Bios to know how to configure those settings.
• I also read about Grub probably not installing on the SSD and I might just have to fix Grub for it to work, but I haven't been able to do that through the Ubuntu running of the USB stick.

Any help or links to good threads would be very helpful. If you have any questions, I would be very happy to help you in helping me.

When I nmap localhost get this:

What is it and do I really need it? I tried to remove it with

sudo apt-get remove dnsmasq-base

but it said if I would continue it will remove network-manager and network-manager-gnome too. So do I need it for network-manager and network-manager-gnome or if I don't can I just remove it because I don't want to have it listen on port 53.
