"Not sure if this is relevant or a different bug, but when booting to CSM mode
with one or two external monitors (in which case there's no image in the
internal monitor), occasionally I can't get past the login screen. Kernel log

See comment 137, https://bugzilla.kernel.org/show_bug.cgi?id=59841#c137 - I've
seen that several times, but it didn't happen always. Could be it fails on only
external dislay and possibly even always on external, but not sure. I'm
compiling current git://people.freedesktop.org/~danvet/drm-intel to see what
happens with it."
"Created attachment 110201 [details]
Dmesg Asus TX300 CSM with patch 110101 and quirk & mod param patches
Here's a dmesg from drm-intel git tree with patch 110101 and my quirk & mod
param patches applied.
While the version works fine on UEFI, in CSM mode there's no image on the
internal display when an external monitor is connecte, and I can't log in even
with the external display. I reported a similar (maybe the same) issue in
comment 137."

IIUC, this happens with the otherwise working drm-intel-nightly + CSM combo
too? Please file a new bug about this on DRM/Intel at:
https://bugs.freedesktop.org/enter_bug.cgi?product=DRI
We can't tackle all of these in one bug."
