Bug ID: 395499
Summary: Cannot change resolution after installing kernel 4.17
Product: KScreen
Version: 5.13.0
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: common
Assignee: se...@kde.org
Reporter: alge...@tuta.io
Target Milestone: ---
Running latest KDE plasma on Arch Linux on a Dell XPS 9560 laptop.
When I boot mainline kernel 4.17, I can no longer change the resolution for my
laptop screen under System Settings->Displays. It's stuck at 4k, and if I click
the dropdown and select 1920x1080 and hit apply, it just resets to 4k and
nothing on the screen changes. I installed xorg-xrandr and was able to manually
set the resolution using the xrandr command.
This problem does not occur when I boot the stock 4.16.13 kernel. Under 4.16 I
can change the resolution in the Display settings as expected.
