Chrome Causes Segmentation Faults in libnvidia-glcore.so.390.25 With KDE neon (Ubuntu with plasma)

Hi. My desktop keeps crashing. I have a fresh install of KDE neon 5.12

For explanation; KDE neon is an LTS Ubuntu (currently 16.04) without its default GUI (called unity), it uses “Plasma 5” instead.

My graphics card is GTX 770 and I’m using the nvidia proprietary drivers 390.25. I installed it from the ubuntu’s graphics drivers ppa (here https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa ) so I did:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt update
sudo apt install nvidia-390

I get crashes at random times, but here’s what may help reproduce it. I have google chrome. I open many (MANY) chrome windows, and each has many tabs. Try opening a tab with google maps. I get some weird lag in the cursor!

Also the crash mostly happens when I “show desktop grid”. To do this you have to have virtual desktops. Just search for “virtual desktops” and add some (I have 16 of them), then press Ctrl+F8

When the crash happens the mouse and keyboard are active. I go to the tty (Ctrl+Alt+F1) and type dmesg and I see segfault in libnvidia-glcore.so.390.25

p.s: I’m re-posting this: https://forums.geforce.com/default/topic/1038512/geforce-drivers/segmentation-faults-with-kde-neon-ubuntu-with-plasma-/?offset=3#5297084

bump :( anything?

bump. it’s still happening

Attaching the output of the debug script. I’m still experiencing the same issue but I can’t locate the segmentation fault in dmesg anymore.

You’re getting kernel oopses regarding ext4 and nvidia and segfaults from thumbnail generation. You should check your memory and harddisk.

Hi, we’re currently investigating an issue related to virtual desktop switching in KWin that may be similar to what you’re experiencing. Would you be able to describe in more detail what you see when the crash occurs? Specifically, do all the window decorations (title bars, ect.) dissappear?

Another thing that might be helpful - could you run the following command

$ kwin_x11 --replace

and then try to trigger the crash and post any output?

Thank you for your reply.

The display just “freezes” as it is. Only the mouse can move. The rest visually stays the same as if it’s a still frame of a camera.

I’ll try the command but the crash happens sort of randomly. But it does seem to happen specifically when I’m either switching the virtual desktop or when I’m displaying the grid of the virtual desktops. I work with 16 desktops. A 4x4 grid.

Note that when the crash occurred, I think I tried

$ kwin --replace

before but as far as I recall it didn’t work. I got some output that it couldn’t connect to the X server or something. I’m just trying to remember this part from memory. I hope I didn’t confuse situations with each other.

Thank again. Much appreciated!

…recently I’ve updated the graphics driver to 396. Do I try with the new version of the drivers or do I need to use 390?

Thanks for the info!
If this is related to the issue we’ve been investigating, it should reproduce using 396 as well so you should be fine using what you’ve currently got installed.

Note that you should try running

kwin_x11 --replace

before the crash occurs. This will allow us to have a look at KWin’s output to perhaps get some insight into what’s going wrong.

I understand that. I’ve issued the command and I’ve been playing around for a while. I can’t reproduce it. It’s so random.

Got it! :D

Would it be possible to get the output from the kwin command? Here is the Kwin bug tracking the issue https://bugs.kde.org/show_bug.cgi?id=386370 and OpenSUSE also has a bug tracking the same thing https://bugzilla.opensuse.org/show_bug.cgi?id=1101560

Do the comments there align with anything you’re seeing at all?

Hello! Sry I haven’t replied since then. I’ve been away. Next time the crash happens I’ll make sure to capture the output of the console in which I ran the kwin command.

Also when I first run the command these are the lines that I get:

…so actually I don’t know how to do this.

The problem is that if I run the kwin_x11 --replace command in a regular console window. I will not be able to capture the error because the whole screen freezes when the error happens.

…and I can’t run the command in a tty. It just says “fatal error cannot open display” something like that. It’s because I’m not specifying the correct display or something. I think there’s something that I should add to the command for it to work from tty.

I tried doing DISPLAY=0 kwin_x11 --replace

I finally learned how to EXACTLY reproduce the bug. I could do it 5 times the same way. It has to do with the notification box that appears on mouse-over. If I can trigger “show desktop grid” while it is appearing, everything just freezes.

Here’s a video explaining how to reproduce it. https://youtu.be/_l1ab_PLP7Y

I think that a different thread should be opened for this topic. It has nothing to do with google chrome now or segfaults. I’ll change the title for now.

Let’s open a separate thread.
