Bug ID: 390977
Summary: Turning off display with xset results in screenlocker
freezing when display is turned on again
Platform: Archlinux Packages
CC: bhus...@gmail.com, mgraess...@kde.org
Target Milestone: ---
Version: 5.12.2 (could not find relevant option in dropdown)
Steps to reproduce:
1. Set the command 'xset dpms force off' to be run on screen locking.
2. Lock the screen
3. Move the mouse to activate the display again.
4. Switch to a tty and switch back the the graphical display.
After step 3, we find that the screenlocker does not update the display (for
eg., does not display stars or cursor when typing password). However, the mouse
cursor is movable. After switching to a tty and back, the screenlocker behaves
normally. If we type something after step 3, and then perform step 4, we see
that stars are shown in the input box. One can also 'unlock' the screen by
typing the password and pressing enter. However, the display does not update
until we switch to a tty and back.
The screenlocker should update the display accroding to input after the display
is turned off and on again using xset.
I am using Intel integrated graphics, on Arch Linux. Downgrading the
kscreenlocker package to 5.11.5 fixes the issue.
