<pre>HW: Dell 7350 Intel HD520.
SW: Gentoo, kernel 5.2.11, ~amd64, Wayland setup.
When using
MESA_LOADER_DRIVER_OVERRIDE=iris
in /etc/environment, gdm freeze. Only printed lines into logs are:
gnome-shell[932]: meta_drm_buffer_gbm_new failed: drmModeAddFB failed:
Nepřípustný argument (translated as Unacceptable argument)
gnome-shell[932]: meta_drm_buffer_gbm_new failed: drmModeAddFB failed:
Nepřípustný argument (translated as Unacceptable argument)
I tried compile git mesa with debug, but it didn't get me further.
Feel free to ask me to get specific debugging, can compile mesa/libdrm or
kernel with specific patches.</pre>
