graphical errors with X11 on an x230

Joedang · 2021-03-04 02:50:39

I recently started experiencing some inconsistent graphical errors. I'm not really sure how to begin diagnosing the issue.

Sometimes windows don't update their contents immediately or display old contents. (For example, if I open htop in a terminal, it might flash htop, flash the old terminal contents, and then go back to htop.) Rarely, the drawing order is wrong or windows show all-black contents. It seems to not happen immediately after rebooting, but returns after a few hours. Sometimes the effects are mild, but sometimes they make programs borderline unusable.

This doesn't seem to happen in a virtual terminal, as far as I've noticed. It happens in multiple desktop environments (XFCE, i3-gaps, LXDE). It also happens whether my compositor (picom) is running or not. This is happening on a Thinkpad x230 with Coreboot firmware and up-to-date packages.

What might be going wrong and what logs/tests should I look into?

So, I'm inferring that I'd need to add i915.enable_dc=0 i915.enable_fbc=0 i915.enable_psr=0 intel_idle.max_cstate=1 to GRUB_CMDLINE_LINUX in /etc/default/grub, correct? How would I have determined that this was necessary, and how do I find out what these options do? Most of the options are mentioned briefly in this wiki page, but i915.enable_dc is not.

(I don't have xf86-video-intel or modesetting installed.)

modinfo i915

Will provide a list of options for the module along with a description.
The X modesetting driver is part of the xorg-server package and is used by default when no other driver is installed.

We haven't determined anything yet, but are just rounding up the usual suspects.
