Plasma6 plasmashell kscreenlocker_g freeze after waking from suspend using nvidia

English Applications
,
1

Using tumbleweed, over the past 3 months I always suffer from plasmashell frequent freezes that occurs post suspend/sleep using nvidia-G06 drivers.
I’d to pkill -1 plasmashell ; plasmashell --replace & multiple times after awake or even go to virtual konsoles and pkill -1 kscreenlocker_g to be able to unlock the desktop.
The desktop frequently hangs and there seem to be performance issue after suspend that does not easily recover.
plasmashell could be seen using 100% CPU and does not respond until killed/interrupted as mentioned.
Tried to strace the stuck process I could not get any useful info though.

Sometimes also the issue occurs with a screenlock, leave it until screen it turned off for few minutes then try to unlock.

Here is output of inxi -G

I’ve just made a zypper dup and sure that the issue persists.

What else can be done to troubleshoot the issue or report a bug?

I’ve also simplified the kernel boot command line options as follows and I’m still having the same issue:

quiet splash showopts rd.luks.options=discard,no-read-workqueue,no-write-workqueue rd.plymouth=0 plymouth.enable=0 mitigations=auto
3

The issue for sure is nvidia related, as when I boot without nvidia card, no problem occurs.

I’ve reported it on nvidia too

I can confirm the bug on Tumbleweed longterm-6.12.x kernel too

@Raviu So I see your using S0xi on this system? EnableS0ixPowerManagement: 1

I use Intel ARC/RTX4000 on this system with GNOME but no S0ix…

My boot options are fbdev=1 nvidia_drm.modeset=1 rd.driver.blacklist=nouveau

The other thing I do is make sure libvulkan_intel isn’t installed and use a /etc/environment file containing `MESA_VK_DEVICE_SELECT=“10de:1eb1” for my RTX4000 so it’s used for vulkan and not the intel.

Now I use the run files for cuda/driver (MIT/GPL), but shouldn’t be an rpm issue.

I only run Wayland, you could try switching to that instead of X11.

I note on your earlier output guc=3, that is not needed on newer intel GPU’s it’s detected/used…

Something like suse-prime and bbswitch hasn’t been installed?

@malcolmlewis

So I see your using S0xi on this system? EnableS0ixPowerManagement: 1

Actually I do not know what this is, I found it enabled by

rpm -qf /usr/lib/modprobe.d/50-nvidia.conf
nvidia-common-G06-570.153.02-36.1.x86_64

Disabled and rebooted, made sure it’s off

$ grep S0 /proc/driver/nvidia/params 
EnableS0ixPowerManagement: 0

My boot options are fbdev=1 nvidia_drm.modeset=1 rd.driver.blacklist=nouveau

I’ve also applied your boot options now cat /proc/cmdline shows

quiet splash showopts rd.luks.options=discard,no-read-workqueue,no-write-workqueue rd.plymouth=0 plymouth.enable=0 mitigations=auto fbdev=1 nvidia_drm.modeset=1 rd.driver.blacklist=nouveau

The other thing I do is make sure libvulkan_intel isn’t installed and use a /etc/environment file containing `MESA_VK_DEVICE_SELECT=“10de:1eb1” for my RTX4000 so it’s used for vulkan and not the intel.

I cannot remove libvulkan_intel as it’s required by wine packages, however I’ve applied MESA_VK_DEVICE_SELECT

$ echo $MESA_VK_DEVICE_SELECT 
10de:2704

I’d several issues previously with wayland, and I know that X11 is better supported for nvidia up until now at least.

Something like suse-prime and bbswitch hasn’t been installed?

No, because I’m using dual multi-seat setup, each using its GPU.

By the way, I know at least 3 friends suffering from the same plasma6 freezing issue for few months already too using Tumbleweed on different laptop models with nvidia - and suse-prime -

11

I forgot to mention that the issue persists after applying all your recommended changes.

12

@Raviu Suggest you try Wayland as going forward this is what is supported…

Likewise if running newer Intel/AMD/Nvidia cards use switcherooctl, not suse-prime.

I don’t run Plasma so it could be related to the Desktop Environment… I have three Intel/Nvidia setups running GNOME without issues.

13

Tested on wayland, the issue seems to be resolved. I tried 2 times, plsama does not freeze, mpv restores video fine.
However I got other issues, like firefox not scaling well on my 1440p monitor. I tried the solution in HiDPI - ArchWiki to set widget.wayland.fractional-scale.enabled , but when I scale over 125% the fonts are blur. I did not have such issue on X11

14

@Raviu I suggest you start a new thread on the HiDPI issue.
