Frequent screen flickering on the X11

I have recently updated the system to linux kernel 6.9 and libplasma 6.0.4-1.1 and it was running on the Wayland (without Nvidia GPU) earlier with very less frequent flickering, but it was causing problem with CPU intensive task, so I had to switch to Xorg which is configured on the Nvidia GPU but here the flickering the more frequent than wayland.

Key Points

  1. On 144Hz it is hard to see any text as the flickering very very frequent and takes some time to load the screen, so I am running 60 Hz.
  2. I recently got my laptop display fixed ref

Additional Note: It fickered more than 10 times while writing this post. Luckily keyboard inputs are not getting lost or what ever but they are buffered and then appear all in once. I usually have fast typing speed.

Update: I am running 6.8.9-3-MANJARO, and flickering happened during splash screen and it still happen but infrequent and for very short time (impulse of flicker)

I can’t exactly tell if that helps, but it could help… because it fixed flickering that i had long time ago till nvidia fixed it with their drivers.

You can maybe try this out.

Nvidia Black Flickering/Flashes workaround:
In /etc/default/grub “add” nvidia_drm.modeset=1 to the GRUB_CMDLINE_LINUX_DEFAULT line:


Save the file and after you done this command:

sudo update-grub

Don’t replace the line, just add this command: nvidia_drm.modeset=1

first, you’re on intel (sgi) and not on nvidia
second, this update installed only the hardware-acceleration for wayland and the x11-hardware acceleration must be installed manually

 echo $XDG_SESSION_TYPE && glxinfo | grep server

sgi ? → switch to nvidia

libva-vdpau-driver-wayland installed but


not ? install the package

Then why nvidia-smi show Xorg process?

I can’t reach to the greeter session after adding this, is there any to fix this or should I prepare live boot and then edit the group file?

In 6.8 kernel

In 6.9 kernel

It sounds like the plymouth bug, prepare live boot and chroot,
then remove splash from grub… you can still add nvidia_drm.modeset=1 if you want.

Save the file and…

sudo update-grub

If it is a plymouth issue you don’t need to boot from a live image to get into your system. Spam the SHIFT key after boot to bring up the GRUB menu, press E to edit kernel parameters, and remove splash.

That is only temporary so you still need to update grub once you’re in.

Nope, not working that either. I will try to remove this from chroot. and test again
