Description Alexander Tsoy 2019-09-24 20:05:15 UTC
Many distributions already switched to using modesetting driver for gen4+ Intel GPUs by default (e.g. Fedora [1] and Debian/Ubuntu [2]) due to multiple problems in intel ddx. Please consider doing the same in Gentoo.

Personally I was forced to use modesetting driver on one of my Intel systems due to long standing bug [3].

We already do this when VIDEO_CARDS="intel i965" in make.conf

What do you propose exactly? Patching xf86-video-intel to only work on Gen < 4?

Using VIDEO_CARDS="intel i965" already does not pull in xf86-video-intel, so you'll get modesetting.

Some people insist (against my suggestions) on using xf86-video-intel.

Oh, I haven't noticed that VIDEO_CARDS="intel i965" doesn't pull in x11-drivers/xf86-video-intel. So maybe it should stay as it is.
