Public bug reported:
Ubuntu crashes after connecting an external display, in this case a TV, to my
laptop's HDMI port and logs out. After logging back in, the HDMI port seem to
be disabled, as nothing happens when unplugging the cable and plugging it back
in.
Some extra info I can provide:
- It's a Lenovo Legion laptop with an HDMI port connected directly to an RTX
3070ti
- My nVidia driver version is 580.82.09
- The CPU is intel and it has its own Intel GPU
- Before crashing, the Terminal opens and displays this error:
[ 174.246XXX] nvidia-modeset: ERROR: GPU:0: Failed to query display engine
channel state: 0x0000c67d:0:0:0x00000062 (This line repeats numerous times with
those XXX different each line, until next line appears and Ubuntu logs out)
[ 174.967589] nvidia-modeset: ERROR: GPU:0: Timed out waiting for core channel
idle.
- The same TV works if connected via USB-C
- I found only one post on the internet from someone who had the same error and
"fixed it" by rolling back to nVidia driver version 580.82.09
(https://forum.endeavouros.com/t/lenovo-legion-laptop-nvidia-drivers-580-95-05-tv-screen-freezes-the-system/75600/3)
- It's no necessary for me to detail the steps to reproduce since there is only
one step: plug an HDMI cable
