Comment 12 for bug 1855608

@tjaalton I recently switched to Debian, it's difficult for me now to test Ubuntu kernels. I tried on i915.enable_psr=0 on broken Debian kernel linux-image-5.4.0-4-amd64 (5.4.19+1): Screen corruption persisted. Let me know if you need to have it tested with an Ubuntu kernel, I'd try Ubuntu 19.10 live usb thumbdrive then.

@kent-jclin I guess your question for EDID data was already answered. In case it wasn't, this is what I got from /sys:

packet@xps:~$ cat /sys/devices/pci0000\:00/0000\:00\:02.0/drm/card0/card0-eDP-1/edid | hexdump -C
