While playing games on Kubuntu 25.10 and 26.04 (Both fully updated at the time of testing), my primary monitor, the monitor I'm playing on, will lose signal and will require me to turn it off and on again before working. The game still runs while this is happening however and resumes after a power cycle.

So far I've tested:

• Runescape: Dragonwilds - Steam (Proton) version
• Cyberpunk 2077 - Steam (Proton) version

Both using DX12, since Vulkan seems to be pretty laggy and does not have great reviews on protondb for RSDW.

Display configurations I've used:

• 2560x1440
• 100% scale
• Refresh Rate: 144hz
• Every option for Adaptive Sync
• HDR on and off
• Every option for Color Accuracy
• Not a replica of a display
• Screen Tearing on and off

Is there a way to fix this? It's really getting annoying and makes me unable to play multiplayer games.

I am testing the pre-release of Ubuntu 24.04 Noble Numbat on my Zyrex D-Tech laptop (AMD based). I am facing a critical issue where both the internal keyboard and external USB keyboards are completely unresponsive once the OS boots.

Things I have verified:

The keyboard works perfectly fine in the BIOS menu.

I have tried several GRUB parameters manually: i8042.nopnp, i8042.direct, atkbd.reset, and acpi_enforce_resources=lax. None of them worked.

Even an external USB keyboard is not detected, suggesting a possible I2C/PCI bus issue on this AMD hardware.

Personal Note:

Honestly, I have spent hours trying to fix this. Since the keyboard is dead, I had to manually type long terminal commands on my smartphone's keyboard just to edit the GRUB file. It was an incredibly frustrating experience that almost drove me insane.

Please look into the HID/Input drivers for these AMD-based local laptops (Zyrex) before the final release in April. I really want to use Ubuntu 24.04, but I can't even type a single letter right now.

Thank you.

What have you tried: alot thats got me in an even more of a mess

What device is this on: Dell Inspiron 15 3000 laptop

hello everyone. im back using kali linux 24.04 after quite a break away so ive forgotten so much. im trying to install preload to speed things up a bit but when i write : mark㉿kali)-[~]apt install preloadPackage preload is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, oris only available from another source

Error: Package ‘preload’ has no installation candidate.

so that led me to trying to upgrade kali linux repositories to add universe repository. i dont know quite what ive done but i cant install universe repository and its led me to the above error messages when i write sudo apt update

can someone please help me fix this. including howto install preload.

thanks in advance.

It won't boot and im really confused and this is my first installation

I'm using Ubuntu with a Sun Type 7 Unix keyboard since years. My Keyboard setting is "English (US, Sun Type 6/7)". As a German I'm very often using the Compose Key to write German diacritic characters like äöü and others. I'm also naming files using diacritics.

Recently I’ve upgraded my system from 22.4 to 24.4. Since then "Files" shows a strange behaviour when renaming a file using the compose-key to create a diacritic in a file name. In addition to the desired diacritic character always the accent-sign used to compose the diacritics is shown travelling right while typing more characters. However, when pressing enter to finally rename the file the extra accent does not appear in the new file name. Using the back-space key while typing to get rid of that travelling accent deletes not only the accent but also the last character typed.

I'm aware that this is a minor flaw. Nevertheless, I wanted to make it known to the community. Maybe a developer has a clue what's wrong.

I have issue with one key on my laptop keyboard. It gets stuck and computer thinks i am holding it. A temporary solution is to delicately rub the key to make it work again. WARNING!: Any solution that makes the key unusable on usb keyboard too will be ignored.

I have a Dell precision R630 Server with 4trb hard disk space on raid 5

is there is a way to make the main partition bigger?

Please advise.

Thank you

laptop and external monitor is mirrored.

fractional scaling on, and scaling at 125%.

close the laptop lid and the external monitor gets zoomed and most of the screen is out of bounds/viewport. Open the lid, it pops back to correct setting. Close the lid, it gets out of bounds.

Ubuntu 25.10, Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)

When waking up my computer by pressing a key on the keyboard after suspend, it takes from 2 to 10 minutes for the screen to lit up.

I am welcomed with this screen for about 5 seconds

Then I finally enter gnome, however my wired connection is unavailable.

Everything is fine if I boot from cold, it only happens after suspend.

Do note that I had to install r8125-dkms to make the wired connection work in the first place.

After updating to Ubuntu 24.04.4 LTS, my cheap ThinkCentre M910q machine no longer boots into the GUI. It drops to a TTY1 login prompt every time.

Diagnostics

• Hardware: Intel HD Graphics 530 on a cheap Lenovo ThinkCentre.
• Service Status: gdm.service is marked as Started, but no GUI appears.
• Manual Fix: Running sudo systemctl start gdm from the TTY works perfectly and loads the GNOME desktop.

Logs (journalctl -u gdm)

The logs show a specific assertion failure during every failed boot:

Gdm: on_display_added: assertion 'GDM_IS_REMOTE_DISPLAY (display)' failed
Gdm: Child process -1565 was already dead.
Gdm: on_display_removed: assertion 'GDM_IS_REMOTE_DISPLAY (display)' failed

Things I tried (to no avail)

• Disabled Wayland: Set WaylandEnable=false in /etc/gdm3/custom.conf (reverted after testing).
• Early KMS: Added i915 to /etc/initramfs-tools/modules and updated initramfs (reverted after testing).
• Target Check: Verified systemctl get-default is set to graphical.target.
• Package Check: Ran apt update && apt upgrade (0 pending).

Would appreciate additional tips - this is quite a nuisance (and other users of this machine won't be happy if the had to run systemctl start gdm every time)

My mother's computer is a 2GB RAM HP Steam, and as you can imagine it has been unused for a while. I am trying to give it a new life using Lubuntu 1.4.0. Everything is alright except for the Wi-Fi connection to the internet. It is my first time using a terminal and I have already tried multiple ways to update the drivers and none of them have worked.

I started here: Installing Broadcom Wireless Drivers and have been trying to fix the errors that appeared along the way until getting to this tutorial: https://forums.linuxmint.com/viewtopic.php?p=2749276#p2749276. And it still doesn't work.

Here is my terminal output.

I have been at it since yesterday and am currently losing my mind. Does anyone know what is going on? Also please explain in a very simple way. I am a first time terminal user and am in way over my head.

Installing Linux Ubuntu 24.04.2 LTS to older iMac from flash drive. I get past EFI boot option. I edit boot entry with “nomodeset” at end of line. I press F10. Then it gets stuck at “Booting a command list”. Any help?

I have newly installed Ubuntu 22.04 LTS on an old desktop.

I managed to install nextcloud server version 24. I am trying to find the trusted domain php file to add a trusted domain. Can anyone point out the path to get there, or any source of info where I can read about it? I can't find the information on the nextcloud forums.

I used to be able to find it in /usr/local/www/nextcloud/config/config.php

First time Linux user.

I'm trying to get Ubuntu fully installed on an external SSD connected with a USBC cable. I want it to be fully installed, so it can work on any computer. The linux flashed thing is on a USB. The problem is that during the 'copying files' stage of the installation, I get Errno 5, Input / output error.

The first time I tried, I didn't realise I needed to disable the boot flags on the internal windows HDD. Linux was installed correctly with no errors - I could see the file system - but I couldn't boot from it.

The second time I tried, I disabled the boot flag on the internal hdd. Now when I try to install linux on the external SSD, I get the aforementioned error. I tried again and ran ubiquity no-migration-assistant before trying to install, but I got the same error.

Any thoughts?

Specific information:

• Secure boot is disabled. Fast boot is disabled. The laptop has ahci enabled.
• Version of linux: 22.04 LTS https://ubuntu.com/download/desktop
• The computer is an Acer i7-3537u, 2.0ghz, 4GB memory, 500TB HDD, with USB 3.0 and a nvidia geforce grafics card. Windows is installed on the HDD (I do not want to touch this HDD).

I'm switching from Linux Mint to Ubuntu, having created an installer of 21.10 on a USB stick. When booting into the "Try Ubuntu" mode, my wifi adapter didn't work out of the box. So I went to the Additional Drivers section of the Software & Updates application and enabled the proprietary driver (Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source) for a BCM4352 802.11ac adapter.

That works like a charm. After enabling the driver, I can connect to a wifi network, browse the internet, etc... This is exactly what I had to do in Linux Mint as well, which isn't surprising since that one is based on Ubuntu.

So after confirming that wifi worked, I installed Ubuntu. I picked the option with the additional software and also checked the checkbox to install third party drivers. After the installation completes and I reboot into the new installation, I try to repeat the steps of enabling the wifi adapter, but when I click on Apply Changes, I get the error:

pk-client-error-quark: Cannot download packages whilst offline (257)

To try and fix the issue, I've plugged in the installation USB, went to the Ubuntu Software tab and made sure that it is checked in the "Installable from CD-ROM/DVD" section. No good. So I tested installing a random package from the command line with apt-get and the error message suggested that it was looking in /media/cdrom for the installation disk, where it was mounted in /media/username/[something]. So I created a link from the mount point to /media/cdrom and the command line installation worked.

But, activating the proprietary driver still returns the same error and it won't let me activate it.

It's a bit baffling that the process works perfectly fine in the "Try Ubuntu" mode, but it completely refuses to do the same thing when installed to disk.

The built-in microhone from my laptop does not work. When I introduce an external microphone, that external one does work so it seems to be an issue with the internal one only.

I'm on Ubuntu 20.04, fresh install. My laptop is Asus X550LD.

I've tried few possible solutions: 1) installed pavucontrol to check if the micro was muted but was not, also not responding there; 2) installed vokoscreen to make an audio recording, can only hear noise, not my voice; 3) in pavucontrol I tried to mute the "front right", also did not work (some users recommended to try this).

I know that the microphone itself is ok because I've just changed OS and it was working before.

This is my hardware:

I had installed Ubuntu on my Lenovo Yoga 530.

After a bumpy start it did work, but not very smoothly. I managed to install Ubuntu by turning off security mode and started it with the safe graphics option.

It would start crashing more often, so I reinstalled Ubuntu 20.04 by using a USB flash drive. The installer crashed and I could only access Ubuntu live CD, but then either the keyboard or the mouse cursor didn't work.

I tried replacing the ISO image and did a checksum check.

After several tries I couldn't reach live CD anymore and I would get a message that it couldn't load initramfs. then it would do a filesystem check and I ended up with a kernel panic. That's where I am now.

I had quit for some time and returned now to see if I can fix this issue somehow.

I'm not sure if this information his helpful. I have some text files from when I could still reach a terminal: casper.log, dmesg, kern.log, syslog, hwinfo.txt (where I stored some hardware information). If you wish to see the content of any of them.

Maybe I could try to install a different distro. Would this be helpful?

Ubuntu 20.04 freezes whenever I am running any sort of virtualization software. Itll be running fine and then all of a sudden the host just freezes. Nothing is active - keyboard, mouse. The video stops playing, audio just keeps on looping through the last word that was said. I've waited 5 mins and it just never recovers.

Ive tried VirtualBox, VMWare and even GNOME Boxes with the same result.

I'm running Nvidia GEforce GTX 1060 3GB.

I picked up these from the log:

11:16:55 AM systemd-udevd: /etc/udev/rules.d/60-brother-libsane-type1-inst.rules:14 Invalid key 'SYSFS'
11:16:55 AM kernel: Initramfs unpacking failed: Decoding failed

Updated for further info request

free -h output - I am not running the VM now since I don't want a crash:

I have assigned 8 GBs of RAM to the guest and 4 CPUs. I do have the same set up under Windows ( dual boot ) on the same system which runs smooth.

I am a complete newb after ditching Win 10 for Ubuntu so go easy on me & be clear with your writing points. I joined this site 5 minutes ago specifically to ask this question.

Yes, I've been to the Canon site and downloaded the driver tarballs which I successfully extracted . Now what?

Despite all my best efforts I have no idea how to install the drivers and get the scanner going. I searched all over (including this site), and nobody seems to know a working solution.

Kindly point out in very simple terms how to install and setup the above scanner on the version of Ubuntu given. Imagine I'm totally retarded in your detailed & thorough working "How To" explanation. Much appreciated.

Thanks all,

I very much appreciate all the time and effort spent helping me, a complete stranger.

A lot has changed since I first posted. I did get my device working, although I have no idea how. I worked though all your helpful suggestions and something "clicked".

I moved on to try Mint 20 to give that a whirl. I experienced the same problem there that couldn't be fixed by the methods given. Strange, because I thought Mint is based on Ubuntu?

So, I ditched that in favour of Manjaro KDE where similar issues occurred with my Scanner plus all my Audio is screwed up no matter how I changed the settings according to online help posts. Out of frustration I changed yet again to the Manjaro Gnome variant where everything works fine "out-the-box".

I'm still considering building a system where Debian is alongside Arch and instead of "Distro-Hopping", merely change the settings in Arch or Debian with the tools available to make the unique version tailored to specific need.

Thanks again all. This matter can now be considered closed.

Note: I'm interested in knowing if there's a shortcut native to gedit itself. I'm not interested in solutions involving Autokey, etc.

In gedit 3.28.1 (Ubuntu 18.04) and 3.30.0 (Ubuntu 19.04), if I want to insert the date and time (assuming the corresponding plugin is active), I need to

1. Click on Menu (☰)
2. Click on Tools
3. Click on Insert Date and Time …
4. Click on Insert

This page doesn't list a keyboard shortcut even to get directly to step #3 in the list above.

(I know there are other ways such as using xdotool and xsel to insert time and date.)

The .cache folder(The folder with cache) is eating up my space most of the time and I always how to clear it. How do I get Ubuntu to automatically delete every cache file, including clearing the recycle bin whenever it deletes it but only files that were in the cache folder not the ones deleted by me?

Unfortunately, I installed kernel 4.4.0-108 before seeing the relevant answer:

Kernel panic after update to 4.4.0-108-generic

I have already discarded the problematic kernel (purged) and switched to 4.4.0-109 and as of today to 4.4.0-112, but one problem still remains: the failure to reboot the system. Everything else seems to work fine, except from the rebooting operation.

I have a Haier HV102H laptop-transformer with Windows 10 and Ubuntu 16.04 on board, but there is a problem with the WiFi adapter (Broadcom 802.11n Wireless SDIO Adapter). There is no device visible in the output of lspci or lsusb and no network interface visible in the output of ifconfig. WiFi isn’t working. Windows driver installation (by NdisWrapper) and kernel upgrading (up to 4.12) did not help.

It's not a hardware problem: on Windows everything works sucessfully. What can I do to connect Ubuntu to WiFi?

sudo lshw -c network outputs nothing.

After putting new file to /lib/firmware/brcm:

$ dmesg | grep -e sdio

I've just upgraded from 14.04 to 15.04 & want to solve a problem with Nvidia drivers I've had for a while. I'm currently running using Nouveau, but this causes screen scrambles when switching users, or accessing the dash. (Nouveau was OK under 14.04) My Nvidia drivers were fine under 14.04 using nvidia304.125, but caused problems when 304.128 came along. I couldn't manage to revert to 304.125, so ended up with Nouveau which was OK. Having upgraded to 15.04 I find Nouveau to be a bit flaky, I've failed with later Nvidia drivers (up to 346) so would really like to be able to use the 304.125 version, however I am presented only with 304.128 from Nvidsia-current. I have a Nvidia GeForce 6200 Turbocache card which I know works well with 304.125 Ubuntu 14.04 because I still have a boot option to that on a second hard disk which works faultlessly, so... How do I install specifically Nvidia 304.125 drivers within Ubuntu 15.04??

I am using 12.04.4 and trying to connect to a NFS server which allows a blocksize of 64kbps, but the most I can set on the client side with mount.nfs is rsize/wsize=32786. I read that there is a kernel define NFSSVC_MAXBLKSIZE that may be limited to 32k, but I am not sure this is for client or server or both. Whichever, how can I change this, or something else to get a higher buffer size? Thanks,

I would like to find a wallpaper that best suits my resolution. How can I get the resolution just by writing commands in the command line?

I want to edit the metadata of a scanned PDF to assign custom page numbers to different pages. For example, what are now pages 1-3 I might want to call i, ii and iii, and what are pages 4-10, I want to call 1-7. I do not want to change the actual order of the pages.

Is there A) A way to do this at all using free tools; and B) A way to do this "in batch" (so, without having to renumber each page manually).
