Bug ID: 453273
Summary: KScreen 2 behavior when I close my laptop lid should
be configurable in the control center
Product: KScreen
Version: 5.24.4
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: kscreen-bugs-n...@kde.org
Reporter: kde_bugrepor...@snkmail.com
Target Milestone: ---
SUMMARY
***
When I add a second display and configure power settings to do nothing,
KScreen2 moves all windows to the second monitor and crashes both desktops when
I close my laptop lid.
***
After adding an external monitor as a second display in Display Manager,
setting the laptop lid action under Power Management settings to "Do nothing"
and checking "Even when external monitor is connected"
STEPS TO REPRODUCE
1. Install Kubuntu on a laptop
2. Acquire and connect an external monitor
3. Go to Control Center -> Power Management, ensure "Button events handling"
is checked, and select "Do nothing" for "When laptop lid closed", and
optionally click "Even when an external monitor is connected"
4. Edit /etc/systemd/logind.conf, and set HandleLidSwitch=ignore
5. Restart.
6. Login and open some windows.
7. Close your laptop lid.
OBSERVED RESULT
The external screen blacks out and restarts, and all windows jump over to the
external screen. When I open my laptop, the windows don't jump back; I have to
either kill them and restart them (conky) or drag them back. Additionally
plasma desktop seems to crash and restart on both screens.
EXPECTED RESULT
Nothing at all should happen, since I never defined that I want windows to move
to the external monitor.
I recognize the added value of having windows move to the external monitor -
this would be useful if I was using the monitor instead of my laptop monitor.
However, for my use case, this is not helpful.
This behavior would be explicitly configurable in KDE Control Center, so people
who want windows to jump to the external monitor could do that, and people who
don't could configure it differently. I should not need to disable KScreen2 and
use arandr; that's not something a beginner user would even know how to do.
