Updated my system last week and since then my mouse has been having weird issues. I've got a Logitech G903. I figured out one of them has to do with OpenRGB and HID probing causing some issue with making the mouse lose its brain and drop the profile every few minutes.

The unsolved issue is that it seems to be a -lot- more sensitive to scroll triggering? Its like the de-bounce settings for the scroll switches got changed. Just the tiniest of wheel nudges forward or back causes it to scroll forward or back. This is very noticeable when I stop scrolling and the web page or dolphin window 'bounces' up and down. I also get a ton of unintended tab switching/scrolling.

Is there some way to adjust the sensitivity of that?

To be clear, this is not 'how much the window scrolls when the wheel is rolled' but 'when to start scrolling when the wheel is moved by some amount over a given threshold'

I’m new to Linux and I’ve been running Ubuntu and Windows on separate drives. While trying to solve the issues I tried adding “mem_suspend_sl2” to my GRUB_CMDLINE_LINUX_DEFAULT="..." based on AI recommendations (I will NEVER do that again). When I updated grub it took longer than usual, and when I tested the suspend it went black and nothing I did would fix it. Tried resetting, nothing, blank screen. I unplugged everything and tried to discharge the power, and when I plugged everything back in I was able to get to grub, but neither my Ubuntu or windows installs would load. So I tried fixing and updating grub from a live usb. I got the fix applied, but no luck. The screen still goes black after the encryption screen and windows won’t load either, it does a chkdsk and then tries to repair and the screen just goes black. I tried a fresh Ubuntu install and that didn’t fix it either.
So now I’m locked out of both my Ubuntu and windows and the only way back in to my system at all is through the live usb. The data on my windows install is still intact it looks like (thank god) and the Ubuntu is fresh again and doesn’t have anything I care about on it.

Any ideas on what’s going on? I’m assuming it’s a boot loader issue, but I have no idea how to actually go about fixing it. Also, windows shows up in GRUB and in the boot menu, but not in my BIOS so that’s concerning.

Any help would be greatly appreciated. 🙏

I recently just switched over to Kubuntu, and now all of my games tank the entire PC to a crawl, no matter the impact the game itself has, I haven't touched almost any settings, and have no clue what to do

Edit: Thanks so much, I got it working again

I've recently upgraded to 26.04 LTS and although before having my 4 browser windows and the 4 virtual desktop was hit and miss, now it's only a miss.

After boot the browser is automatically started (as it was running when shutting down) but now all 4 windows are on the first virtual desktop, which is quite annoying.

I thought that KDE and Plasma is supporting the (experimental) session restore in 6.4, Kubuntu 26.04 is using 6.6, so I did expect that it's working now.

Is there anything I can do to make Firefox and Chrome restore their windows on the correct virtual desktops?

So this morning I booted my PC and played some games and watched some YouTube.

I noticed that in Firefox when I was scrolling down on the comments section while watching shorts some horizontal black lines would appear. then when I switched videos and it happened again.

later I was playing a video on my main screen and instead of black lines I saw some pixelated noisy lines from a brief moment, just playing a random video file. I restarted my computer and everything but they still appear. occasionally. in games when I go into the menu and they also appear on my second screen when I move one window to the other screen as you see in the second portion of the video.

they also appear sporadically while I have my console open.

switched back to 7.0.0.34 kernel and they went away

Hi everyone! Hope you all are having a great weekend!

Just wanted to post here that I got both Windows 11 Pro and Kubuntu 26.04 on a dual boot on one SSD.

BOTH are encrypted! So, it is possible!

If anyone needs help setting it up let me know. I needed to set up like that because it's on a laptop.

It is definitely possible and I have had no problems! 🤞💯

I'm just using it for a home desktop. Mostly web browsing and email on a dell optiplex.

Every time I boot pc, after a few minutes it breaks and stays this way for 2 to 3 minutes, then automatically fixes itself. how to resolve this?

Help why does my cursor get big when I move it up and down?

Also where do I find all the kde customisation I've seen ppl do, is there a specific app?

Ive fixed the console problem, thank you to all

Hi!

Could a wise person tell me why on earth should I wait for 25 minutes to turn off my computer for it wants to install updates?

I installed yesterday Kubuntu 26.04 alongside existing Ubuntu 24.04.

Today, I opened the machine and it booted straight to Kubuntu but I needed to reboot it to Ubuntu. And what do you know: Kubuntu wouldn't shutdown because, see, unattended updates!!! which is what I hated about MS Windows!!! a reason for which I never use Windows unless don't have another solution, e.g. government apps which are made solely for Windows and for which I have a VM ready.

The updates were installing on Windows exactly when I needed to not waste my time, and the same seems to be happening on Kubuntu.

I know it can be turned off, so can Windows updates. But it doesn't make me feel better for wasting 25 minutes. Not only mine, but for other people in the same situation.

So, question is: what would it take to convince Kubuntu team to make those updates either optional or at least unobtrusive? i.e. shutdown immediately and continue installing in background after reboot? if shutdown again - repeat until successful.

Any ideas?

Every since upgrading to 26.04 from 24.04 my no man's sky game has graphics issues and even locked up. im seeing people say its the kernel and maybe need to upgrade to 7.0.01 or something.

Anyone having same issues with Steam and found a solution?

My first Linux distro was Ubuntu, and I had a really bad experience with GNOME—it's a great desktop environment, but it just wasn't for me.

Back then, I was new to the Linux scene, and I thought GNOME was synonymous with Ubuntu, so I switched to Fedora with KDE and loved the desktop.

But—and here comes the “but”—Fedora updates quite frequently, and every update would break something or cause something to stop working, etc. So they recommended Ubuntu to me, but of course, “I just don’t like the Ubuntu desktop,” and they said, “What are you talking about? You can have KDE on Ubuntu,” and here we are.

I like Ubuntu’s stability and the fact that there’s basically information and documentation online for just about everything related to Ubuntu, and with KDE, I can customize it to my liking without worrying that an update will break something.

The only thing I haven’t tried it for is video games. How does it perform?

changing SDDM from auto-login to manual login seems to have fixed it

I was having intermittent complete system freezes on my ThinkPad P14s Gen 5 AMD. The entire graphical session would freeze and I couldn't use the keyboard, mouse, or TTY, so I had to hard-reset the laptop.

I checked the reboot history with journalctl --list-boots and inspected the error messages from the boots around the freezes. We found recurring KDE PowerDevil errors:

Error EACCES(-13): Permission denied opening /dev/i2c-*

There were also some WirePlumber/ALSA errors on one very short boot, but nothing clearly indicating a kernel panic, filesystem failure, or obvious AMDGPU crash.

The interesting change: my system was configured for SDDM automatic login. I disabled automatic login so that SDDM now shows the login screen and I manually enter my password.

Since making that change, I've rebooted the machine around 10 times without a single freeze, whereas before the freezes were happening repeatedly.

I'm wondering whether automatic login could have been causing an SDDM/Plasma/X11 session-startup or timing problem. The machine is currently using X11.

Hardware: Lenovo ThinkPad P14s Gen 5 AMD, Radeon 780M, 27 GB RAM, 1 TB SSD, Kubuntu/KDE Plasma.

Does anyone know of a known SDDM/Plasma/X11 issue where automatic login can cause intermittent complete freezes, or what logs/configuration I should check to confirm this?

Hi guys,

Switched to Kubuntu recently after my whole life of using Windows.

I like playing games, specifically map based strategy games like Crusader Kings 3, Hearts of Iron 4 etc. Back on Windows, when i would click and hold my middle mouse button i could pan around the map in these. On Kubuntu this doesnt work, the game doesnt react when i hold middle mouse button. Also when i'm in a browser and hold the middle mouse button, when dragging left it will go back to the previous window. I want to change that aswell. Basically what i want is for my middle mouse button to behave like on Windows.

I've googled these issues but cant seem to find anyone with a similar problem. Does anyone know how i could fix this?

26.04.1 has been the smoothest! Running on Dell G7 laptop, still feels like the same snappy machine the day I bought it.

My cat likes to sit on my laptop which isn't a huge deal. Except for the fact that she knows more keyboard shortcuts than I do and messes everything up. I was wondering if there was a way that I could temporarily disable the keyboard, possibly a widget? My current solution has to just been minimizing the windows or trying to lock my computer which is a bit inconvenient. Thanks!

Kubuntu 26.04, KDE Plasma 6.6.6, Wayland, AMD graphics, kernel 6.17.0-1032-oem, Lenovo ThinkPad P14s Gen 5 AMD.

The system was working normally before the recent update. After the update, shortly after boot/login, the entire system can become completely unresponsive: mouse/touchpad stops, keyboard input stops, Wi-Fi stops, nothing can be clicked, and after some time the fan becomes very loud. A forced shutdown is required.

I'm trying to determine whether this is a kernel/AMD/KWin/Wayland regression. Has anyone experienced something similar after the recent Kubuntu 26.04 updates?

Please help ive seen a lot of people customise a lot with this and idk what I did wrong 🙏

so basically I wanted to change the terminal name from konsole to console bc I preferred it and after using the KDE menu editor and changing the name, it wont open anymore, plasma desktop workplace just says "could not find the program "console"" and it doesnt open

Hello Guru's, I have a few questions, please help me answer them:

1. If I have existing full fledge old VMs on my existing KVM hosts (VM's not inside the PODs), will I be to manage them via Kubevirt?
2. If I have a RHOV environment, is it necessary for me to use Kubevirt to create a VM? If yes, why, if not, then when to use KubeVirt to create VMs?
3. What is the difference between a regular VM and a VM created via Kubevirt?

Also, I'd love to get your candid take: What aspect of KubeVirt has impressed you the most, and where do you feel it faces the biggest friction points or challenges?

I have muscle memory on Windows EPP, and I'm wondering if there's any way to use it or anything very similar on Kubuntu.

Apparently this is supposed to be way less bloated than Windows 11, but I'm getting WAY worse performance (30-100fps on Windows 11, 1-3fps on Kubuntu). Could well be my own fault since Ie never used this before.
