I have recently installed Ubuntu 22.04 LTS . and sometimes the whole screen just flashes.

image of my screen looks like this

Everything just starts overlapping each other.
It goes away when you press any key. But I want it gone.

Output of lspci -k | grep -EA3 'VGA|3D|Display':

00:02.0 VGA compatible controller: Intel Corporation CometLake-H GT2 [UHD Graphics] (rev 05)
        Subsystem: Acer Incorporated [ALI] CometLake-H GT2 [UHD Graphics]
        Kernel driver in use: i915 Kernel modules: i915
01:00.0 VGA compatible controller: NVIDIA Corporation TU117M (rev a1) 
        Subsystem: Acer Incorporated [ALI] TU117M
        Kernel driver in use: nvidia Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia

Does anybody have any idea on how to fix this?

  • This is not intended behavior (clearly). I suggest that you report a bug. Be sure to include details about your hardware. In the meantime, if you are currently using Wayland, you may want to login with X.org instead (or vice versa) – Nmath May 03 '22 at 02:35

    Please [edit] your question and add output of lspci -k | grep -EA3 'VGA|3D|Display' terminal command. – Pilot6 May 05 '22 at 08:14
