Bug ID: 427217
Summary: Screen autorotate under wayland fails to detect
tablet-mode on a convertible laptop
Product: KScreen
Version: 5.19.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: kscreen-bugs-n...@kde.org
Reporter: benjamin.henn...@wanadoo.fr
Target Milestone: ---
On a Wayland session, when screen autorotate is enabled only in tablet-mode, it
does not work at all.
The automatic rotation does work perfectly if I do not tick the box "Only in
tablet-mode".
The switch to tablet-mode seems to be detected by Plasma: when entering
tablet-mode the icons in the tray become bigger.
The tablet-mode is also detected properly by libinput and evtest outputs
Event: time 1601576158.041596, type 5 (EV_SW), code 1 (SW_TABLET_MODE), value 1
Event: time 1601576158.041596, -------------- SYN_REPORT ------------
when flipping the screen to enter tablet-mode.
STEPS TO REPRODUCE
1. Open kcm in under Wayland and enable automatic screen rotation only in
tablet mode.
2. Flip the screen to get into tablet mode and tilt the laptop on the side
OBSERVED RESULT
The screen does not rotate.
EXPECTED RESULT
The screen rotates.
SOFTWARE/OS VERSIONS
Linux: Archlinux kernel 5.8.11 (with a patch for libinput to properly detect
the tablet-mode switch)
KDE Plasma Version: 5.19.5
Qt Version: 5.15.1
ADDITIONAL INFORMATION
The virtual keyboard is not enabled by switching to tablet mode either (as it
used to be on a Surface Pro 3 I used to have). The bug may not be in kscreen
itself. I don't know for sure.
