@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 Kernel Packages, which is subscribed to linux in 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 Status in linux package in Ubuntu: Confirmed Bug description: I just received a new Dell XPS 13 7390 laptop. With factory preinstalled Ubuntu Linux 18.04 LTS and the Dell OEM kernel, graphics was severely distorted. The display would constantly flicker with areas of the display staying black or showing patterns of square color blocks. Booting in recovery mode worked, though and I was able to install all updates for preinstalled 18.04 LTS with the OEM kernel. Problems in non-recovery mode persisted after installing all updates. I then updated to Ubuntu 19.04 and changed to "generic" linux kernel image without success: Problem persisted, only recovery mode was usable. I updated once more to 19.10 again without any success. From the perhaps related bug #1849947 I tried latest drm-tip kernel from https://kernel.ubuntu.com/~kernel-ppa/mainline/ drm-tip kernel solves the issue for first boot, but after resuming from suspend, the same issues display issues occur.
