Bug ID: 452397
Summary: [Wayland] Cannot change resolution in external monitor
Product: kwin
Version: 5.24.4
Platform: Kubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: mca...@tecnoguru.com
Target Milestone: ---
SUMMARY
I have a Lenovo X1 Extreme Gen2 with an Nvidia GTX 1650 video card. When I log
in with an X11 session, my external monitor's resolution is correctly set to
5120x1440. However, when I log in with a Wayland session the monitor is set to
3840x1080. If I open the Display Configuration I see the 5120x1440 resolution
is available. However, when I try to set it there is no change (the monitor
stays at 3840x1080 even though the Display Configuration screen says
5120x1440).
As an additional data point, the laptop's internal LCD is 1920x1080.
STEPS TO REPRODUCE
1. Plug in external monitor with a different vertical resolution than the
laptop one(in my case the resolutions are as noted above)
2. Open Display Configuration and change the external monitor's resolution to
its native resolution. Apply changes.
OBSERVED RESULT
The Display Configuration shows the new resolution, but the monitor's
resolution is not changed.
EXPECTED RESULT
The monitor's resolution should change to what is selected.
