TLDR: relevant kernel configs are CONFIG_SYSFB_SIMPLEFB (only on x86?),
CONFIG_DRM_SIMPLEDRM, at the same time it's necessary to disable
CONFIG_FB_EFI and CONFIG_FB_SIMPLE
Hi,
I run Guix System, after upgrading from 1.4 to snapshot gdm refuses to
start even if I disable wayland in its config, it seems to require
kernel drm driver, unfortunately amdgpu absolutely requires proprietary
firmware, so for such situations there is simpledrm.
I tried building custom kernel myself, but build gets killed by OOM, it
appears 8 GB RAM is nowadays very little, I also tried disabling
building wlan, amdgpu, radeon, xe and i915 as they don't work with my
laptop anyway, kernel builds successfully, but then linux-modules
package throws error complaining that it cannot find USB drivers
(what???).
