Title:
linux-image-6.8.0-44-generic breaks HDMI output (-41 works)
Status in linux package in Ubuntu:
New
Bug description:
linux-image-6.8.0-44-generic breaks HDMI output. When I connect to the
HDMI port on this laptop the external screen flickers briefly then I
get "no signal". With linux-image-6.8.0-41-generic the HDMI out works
as normal. DisplayPort over USB C seems to work, but only one of my
two external monitors support that.
There is no obvious error message in dmesg when this happens.
I tried with both KDE and Gnome X11 and Wayland sessions (all 4
combinations). None of that makes a difference.
I'm running in PRIME on-demand mode, and on this laptop the external
display outputs are connected to the Intel graphics (not the nvidia
graphics). That *is* configurable in UEFI settings, but I haven't
tried changing that.
