@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 00000000 00 ff ff ff ff ff ff 00 4d 10 ad 14 00 00 00 00 |........M.......| 00000010 2a 1c 01 04 a5 1d 11 78 0e de 50 a3 54 4c 99 26 |*......x..P.TL.&| 00000020 0f 50 54 00 00 00 01 01 01 01 01 01 01 01 01 01 |.PT.............| 00000030 01 01 01 01 01 01 4d d0 00 a0 f0 70 3e 80 30 20 |......M....p>.0 | 00000040 35 00 26 a5 10 00 00 18 a4 a6 00 a0 f0 70 3e 80 |5.&..........p>.| 00000050 30 20 35 00 26 a5 10 00 00 18 00 00 00 fe 00 30 |0 5.&..........0| 00000060 52 39 39 4b 80 4c 51 31 33 33 44 31 00 00 00 00 |R99K.LQ133D1....| 00000070 00 02 41 03 28 01 12 00 00 0b 01 0a 20 20 00 41 |..A.(....... .A| 00000080 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1855608 Title: Dell XPS 13 7390 screen corruption in 18.04 LTS, 19.04 and 19.10 on Intel Comet Lake To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1855608/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
