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)

    Please edit your question and add output of lspci -k | grep -EA3 'VGA|3D|Display' terminal command.
