[OPEN] ArcoLinuxB Deepin screen resolution

Post by salparadise » Sun Sep 22, 2019 9:33 am

Greetings,

I've been using Arco Deepin for a few weeks - very impressed and very happy. A few days ago after the updates were applied I lost the 2560x1440 screen resolution, which has been automatically detected and applied by all distros from kernel 4.20 - 5.2.13. Both of my Arch based distros - Archman xfce and Arco Deepin, are the same. I've reinstalled both and tried different versions - all the same. All are happily displaying at 2560x1440 until the first boot after 5.2.14/5.3.X kernel update.
I use the nouveau drivers - I have an old nvidia (GT9500) which will not work with drivers later than the .340 version and which do not work at that resolution (even though the Windows nvidia drivers for the same card work at full QHD). I've tried xrandr and that resolution is missing from the list.
I've got Solus running on a spare SSD, it has updated to kernel 5.3 and is working at the correct resolution, so it's an Arch issue. The only references I could find on the Arch reddit page were people mentioning this issue but the answers pertained to nvidia drivers, no mention of nouveau.

Has anyone else experienced this? Know of a fix?
Before wiping and reinstalling Deepin I had the pacman cache contents available so rolling back to an earlier kernel was easy. Now the cache is empty.

I specifically said that it was the 2560x1440 resolution that had disappeared. 1920x1080 is not an issue and looks horrible after QHD.
More u pdates came yesterday, including a newer kernel, but alas the problem persists.
