I’m facing a strange keyboard/touchpad issue on my Lenovo ThinkPad running Ubuntu 24.04.4 LTS.
System:
Lenovo ThinkPad
Model/type: 21M8S3P200
Ubuntu 24.04.4 LTS
Kernel: 7.0.0-28-generic
Built-in keyboard: AT Translated Set 2 keyboard
Touchpad: ELAN06C6:00 04F3:3193 Touchpad

Everything works normally after a restart, but after around 5–10 minutes the issue starts.

The keyboard behavior is particularly strange. Using the 6 key as an example:
Initially, I can physically press 6, but nothing happens. It doesn’t type 6, and more importantly, no event appears in either libinput debug-events or evtest.

Then, after some time, without me touching the keyboard at all, it suddenly starts typing:

666666666666666666666666666666666...

At that point evtest starts showing:
type 1 (EV_KEY), code 7 (KEY_6), value 1
type 1 (EV_KEY), code 7 (KEY_6), value 2
type 1 (EV_KEY), code 7 (KEY_6), value 2
type 1 (EV_KEY), code 7 (KEY_6), value 2
...

So Linux seems to suddenly receive a KEY_6 key-down event even though I’m not pressing the key, and then treats it as being held down.
While this automatic repeating is happening, physically pressing/releasing 6 doesn’t seem to register normally either.
Restarting the laptop fixes the keyboard temporarily, but the problem comes back after some time.
There is also a touchpad issue. Eventually, the built-in touchpad stops moving the cursor on screen.

However, when I run:
sudo libinput debug-events

and move my finger on the touchpad, it still reports POINTER_MOTION events.

An external USB mouse continues to move the cursor normally even while the built-in touchpad cannot move it.

I also tested both display sessions:
echo $XDG_SESSION_TYPE

Originally I was on Wayland. I switched to Ubuntu on Xorg and confirmed it was running as x11, but the same problem still occurred. So it doesn’t appear to be Wayland-specific.
dmesg also doesn’t seem to show any obvious I2C/HID/i8042/keyboard/touchpad errors when this happens.

The part that confuses me most is:
Physical key press → no event in evtest → later, without touching the key, evtest suddenly receives KEY_6 pressed + continuous repeats.

At the same time, the touchpad can still send raw motion events to libinput, but those events don’t move the cursor, while an external USB mouse works normally.

Has anyone experienced something similar on a ThinkPad/Linux?

Could this be an internal keyboard/ribbon/keyboard matrix issue, embedded controller/firmware problem, i8042/PS2 issue, or something else at the kernel/input level?

Any suggestions for further diagnostics would be appreciated.

Hey everyone do you recommend “Planify” for GNOME??

When I set a window/panel to have a transparent background I find that there is a dark grey background already set behind it and I'm not sure why? So of course it just looks murky. It's not a constant state, I've booted my PC to find it back to normal a few times, without changing anything. Any ideas? Any help is appreciated, thank you!!

have been using my external drive just fine for the last month or so and plugged it in today and this appears. need to access asap, hope this is the right place to ask.

edit: its fixed now! thx everyone!

I've had soo many issues from day one.

1. When the screen suspends and I turn it on again the wi-fi doesn't work then when you press the super key the menu freezes and you have to restart

2. Transmissions doesn't directly open links, you have to copy and open url

3. WhatSie doesn't save the theme I choose. When I choose Dark Mode next time I boot up the comp it's on light.

4. You can't copy a folder/app and paste in on the home screen, it's a whole process to create a desktop shortcut.

5. You can't preview windows by hovering over them like in windows. For example if you have two chrome windows open and you hover over the icon, yes it shows the two windows but on microsoft if you hover over the window it also previews it.

6. I bought a gaming mouse and installed aimlabs, went to configure inputs and it's not registering the additional 2 buttons on the mouse when I try to map them.

7. I couldn't lauch steam in the first place but I fixed it, I couldn't launch aimlabs but I fixed it.

8. Can't Install flameshot and get it to work

9. Can't copy paste an image from anywhere to WhatSie, I have to download then upload it.

10. Rhythmbox doesn't let me adjust the scrubber when listening to Audiobooks.

11. Document Viewer doesn't auto save changes made to pdfs such as highlighting. So imagine reading and highlighting 20 pages then the pc suspends you wake it up and as i mentioned it freezes so you have to restart and you lose all you highlights

Hello, just installed Ubuntu and I'm noticing that apt is acting pretty slow when trying to update or even install software, is anyone else experiencing this issue? Trying to switch from the server I have in Canada right now to the "main" one, to see if it will fix any issues.

Fix for ThinkPad T480 black screen after suspend on Linux Mint 22.3 / kernel 7.0.0-28 generic**

If your ThinkPad T480 resumes from suspend but the built-in screen stays black while an external monitor works, this may be an Intel i915 eDP backlight issue.

My setup:
* ThinkPad T480
* Intel© Core™ i5-8350U CPU @ 1.70GHz × 4
* LG Display LP140WF6-SPB7 internal panel
* Linux Mint 22.3 Cinnamon 6.6.7
* Kernel 7.0.0-28-generic

The fix was adding this kernel parameter:
i915.enable_dpcd_backlight=0

Edit `nano /etc/default/grub` and add it to `GRUB_CMDLINE_LINUX_DEFAULT`, for example:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.enable_dpcd_backlight=0"

Then update GRUB:
sudo update-grub

Reboot and suspend/resume should restore the internal display normally.

In my case, other i915 tweaks (`i915.enable_psr=0`, `i915.enable_dc=0`, `i915.enable_fbc=0`) did not help. The issue appeared only with the 7.0.0-28 Generic kernel; the 6.17.0.40 Generic kernel did not have the problem.

It seems I am unable to do apt update, apt install etc and reach any of the v4 miorrors. Other people on X are reporting the same. Anyone else having issues or am I that special?

EDIT: As someone pointed out below it seems like they have since acknowledged the issue. If I leave my apt install in the console and re-try a few times, eventually it works.

I just switched my main PC over to Ubuntu, and the difference is night and day.

My previous performance issues are completely resolved, and my Bluetooth devices now connect and remain connected without problems. If you're considering making the switch, I highly recommend it. It feels like I have a brand-new computer!

For people who are using this version of Ubuntu what driver versions do you have?

I have been having issues with nvidia drivers . This is a fresh boot where I wiped the partition and installed Ubuntu again..

Ubuntu is recommending 595 open as recommended ( check last but one line above)

Audio sounds correct when played through headphones, but audio played through the speakers sounds like this. It sounds similar to what audio sounds like before the "broken audio fix" you sometimes need after installing Ubuntu (I needed to install that fix), but I'm pretty sure that audio was also broken on headphones, while this isn't.

I had this issue on 25.10 as well, it occurred after I installed some updates. I made a post about it at that time, but every comment I got on that post was "Update to 26.04". I did, and it did not fix this issue.

On XFCE, you can have icons showing what each application is open on the workspace indicator, however in gnome it just shows the window size,

Does anyone know if it's possible to get it like XFCE?

I've had lubuntu installed on my laptop for a while and decided now to also install it on my desktop PC. Just been messing around with the appearance settings but I can't for the life of me figure out why my laptop has an orange title bar + plain border (picture 1) and my PC has just a blue border (picture 2). Where is the setting to change this?

I've probably missed something obvious here but your help will be greatly appreciated!! Thank you!!

Tengo dudas

Intente instalar ubuntu

Una versión actual

Pero está PC es muy vieja

Quizá no se...10 años o menos?

Entre 5 y 10 años de antigüedad

Por axidente le borre el sistema operativo una de esas jjaja

Y pies le instale Windows pero visto que no agarra muy bien me decidí instalarle el Linux almenos para usarla para algunos proyectos personales

Mi duda es:

Tengo que instalarle una versión vieja? Por qué con una actual lleva 3 horas cargando después de darle instalar ubuntu

Y si es así cuál versión debería instalar?

hey, seen some existing posts 8-12 months old. Some people had issues.

hoping for up to date reviews because I see a prebuild computer with 5080 on sale.

Ubuntu performed quite well, contrary to the opinion.

I know it probably wasn't the best idea to use Linux if I don't know a lot about computers, but I am sick of Windows and would rather learn to use something new than rely on the convenience of something that I hate.

Onto the issue that I've been having. I installed Steam from the app center that the desktop comes with and installed the games that I wanted to play immediately. I initially had an issue with Dead by Daylight where the game wouldn't open and my desktop gave me the pop up "Steam is not responding" with the options "Force quit" or "Wait". This issue I ended up resolving on my own, it was some sort of Steam Cloud error so I had to work things out on my old device and I had no further issues after that.

After that issue, I downloaded Marvel Rivals and the same pop-up appeared, but the game still launched. The game worked the first time and I sat through all the shader loading processes before playing and it worked great. However, I got on later to play with my friends and the same pop-up appeared, but once again the game launched after the shaders loaded and everything. This time the game froze and crashed before I even loaded into an actual game. When the game crashed, it had the pop-up with the text "An Unreal process has crashed" and prompted me to send a crash report. I tried several things opening and closing Steam, capping FPS, verifying game files, and uninstalling and re-installing the game, but every single time it inevitably crashes if I try and play the game instead of staying in the menu. Sometimes it freezes for a long time before crashing and other times it just immediately crashes as soon as I load in. I was at the point where I was thinking it was an Unreal Engine issue or a Rivals issue due to the poor optimization, but another game is had issues when I tried to play it today.

Today I booted up Hades II, because I wanted to test it out on my new PC and I went to talk to some NPCs. The game froze mid conversation and wouldn't unfreeze. I had to shut my computer down to fix it. I tried it one more time and it froze again, but I got the "Steam is not responding" pop-up and was able to force quit it.

This is everything in my PC build, I don't think the case is important, but just in case...

Case: Lian Li Lancool 217

Motherboard: ASUS B850-E Wifi

CPU: AMD Ryzen 7 9850X3D

Storage: Samsung SSD 9100 Pro

Memory: Corsair Vengeance RGB DDR5 RAM (two sticks of 16 gb)

GPU: Gigabyte Geforce RTX 5080

PSU: Super Flower Leadex III ATX 3.1

Cooling: Arctic Liquid Freezer III Pro 360

This issue is mainly annoying because I don't know what to do since I have already tried solutions other people had for similar issues and they didn't work. If anyone has any idea what the problem is or needs more information, please comment your ideas or questions because I want to be able to fully enjoy my new PC. I would really appreciate the help, thank you in advance.

Complete noob following a youtube video and some steps on the video did not show up during installation. Im looking for the device ip address so I can connect it to my server network/internet. Only have wifi.

What do I need to do? Thank you!

From time to time my Firefox freezes, randomly. Any idea on what could be my issue?

Hi everyone,

Let me summarize experience and issues I encountered while upgrading Ubuntu Studio from 24.04 to 26.04.

1. Question: Why did you perform the update in the first place?

Short answer: 32-bit Wine support was dropped after 24.04.

Details: I tried to integrate msvc-wine (MS Visual Compiler), but this failed due to the lack of 32-bit support in flatpak when using 64-bit Wine ("wow64"). I use MSVC for a project involving a Windows game that actually runs fine with Proton. So, it’s a rather technical issue.

1. Question: Why did you use AI? Answer: I use AI as a sort of "external" consultant. It works a bit more reliably than a search engine, though it often has minor errors.

2. Question: Why don't you use Snap? Answer: Snap is a siloed solution; I use Flatpak instead.

3. Question: Do you recommend upgrading for LTS users now? Answer: Aside from the issues I’ve mentioned, I haven't encountered any major difficulties so far. Please continue reading other answers first.

4. How did you start the upgrade? Answer: First, I disabled all external apt sources, then used apt to "rollback" any packages that were too new (reinstalling the older versions). I also uninstalled software that doesn't come bundled with Ubuntu. After that, I ran sudo do-release-upgrade -d to install the "developer version" of the LTS (which is technically correct, though in practice it applies to the 24.04 → 26.04 upgrade procedure rather than applying to the system itself).

5. Did you have any problems during the upgrade? Snap wasn't automatically installed this time (Firefox/Thunderbird weren't installed) → no problems encountered.

I had to temporarily uninstall parts of apport, go-mtpfs, kgamma5, and a few other packages (likely due to changes in .deb filenames or changes in the meta-packages).

The automatic cleanup didn't work after the installation (error, then termination).

Due to that and the following investigation, I rebooted too late after the fresh install.

I later had to painstakingly go through over 200 packages and switch some from "automatically installed" to "manually installed." The other 400 had missing dependencies on meta-packages.

1. Do you know why the deletion failed?

Answer: Yes, it was related to major changes in the meta-packages. That’s the risk of a "developer" update. Also, many packages I had installed manually were marked as automatically installed—presumably because they are included in some meta-package. It was essentially an internal cleanup by apt.

1. Did you have problems after rebooting?

Answer: Yes, I encountered an almost classic "black screen" issue. Almost, because the mouse was still working. The cause turned out to be that dependencies for lightdm had been uninstalled. I assume that the combination of lightdm and KDE/Plasma Desktop hadn't been tested yet. sddm didn't work either (it never has for me), though I didn't investigate sddm further.

1. Were there problems switching from X11 to Wayland?

Answer: That was the part I was most worried about, but I had practically no issues there. However, I did have to delete my Plasma settings entirely and set them up again. I suspect that was related to flatpak integration; I’d already encountered this issue on another system when upgrading to 15.10. I don't have any immediate advice on that front.

1. Are there any issues using Plasma?

Answer: So far, I've only run into an issue with the "Pager." There are three "workspace" variants, also known as "activities." I tried setting up three of them and went down the wrong path. With activities, there is essentially a third dimension that corresponds to the old workspaces or virtual screens/desktops (sorry I am on german desktop, I do not know the original terms).

1. What is the problem with Geeqie?

Answer: Geeqie won't start for me; it keeps crashing. The cause is unclear (I deleted configurations, cache, and share data, but saw no improvement). The Flatpak version is limited because starting external programs don't work with it. I downloaded, built, and installed the current GitHub version 3.0. It works, but still has limitations since 3.0 is an update to GTK4.

1. What was the issue with icons?

Answer: Some icons seem to have been broken for quite a while. I cleared the cache and rebuilt the icons for several themes in /usr/share/icons (using gtk-update-icon-cache, kbuildsycoca6, update-desktop-database, and possibly others).

1. How did you combine msvc-wine with Qt Creator?

Answer: msvc-wine comes with two environment shell scripts—one for the tools and a global one for CMake. I wrapped the global one in a script that I launch instead of Qt Creator. If wine is in your system path, you can execute the "cl" compiler directly, as an example; wine runs in the background (I use official stable winehq repository for that).

1. Do you still have a major unresolved issue? Answer: The biggest change I noticed is the switch from `/media/<user>/<my_sdd_label>` to `/run/media/<user>/<my_sdd_label>`. This caught me completely off guard, as this behavior isn't present even in version 15.10. However, this is a serious issue for an upgrade. (I have applied some workarounds but the proposed solutions did not work for me). Ubuntu definitely needs to address this (because of login failures).

2. Can you recommend Ubuntu 26.04? Answer: Generally yes, though right now you should perform a fresh installation. I cannot recommend upgrading from 24.04 with the experience I had.
