Bug ID: 401581
Summary: Win+P still assumes the monitors position wrongly,
ignoring the Display Configuration.
Product: kwin
Version: 5.14.3
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
MonitorL is on the left, MonitorR is on the right. However, the graphics card
arbitarily assigns Display1 to the right monitor, and Display2 on the left
monitor, and this cannot be changed. I can switch the positions and set
MonitorL (which is Display2) as the primary monitor in Display Configuration,
yet Win+P still thinks that MonitorR is on the left, MonitorL is on the right,
and shows "Extend to left/right" wrongly.
Moreover, when the primary display has been set to MonitorL (Display2), if I
disable MonitorR by selecting "Switch to external screen" and then re-enable it
by selecting "Extend to left", the primary monitor is changed to MonitorR
(Display1).
STEPS TO REPRODUCE
1. Connect two monitors to your computer.
2. Purposely position the monitor that the graphics card think the first
monitor on the right.
3. Change monitor positions in Display Settings, and set the physical left
monitor as the primary monitor.
4. Press Win+P to disable the right monitor and re-enable it.
OBSERVED RESULT
Win+P assumes the positions wrongly. Disable/re-enabling Diplay1 moves the
primary monitor from Display2 to Display1.
EXPECTED RESULT
Win+P should respect the actual positions that is set in Display Settings. The
primary monitor should be remembered (Windows does, for the same situation).
