Bug ID: 512751
Summary: Input focus switches while typing password when
connecting displays
Classification: Plasma
Product: plasmashell
Version First 6.5.3
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Screen locking
Assignee: [email protected]

Target Milestone: 1.0
SUMMARY
Hey there,
I use KDE Plasma on my Notebook that I connect to USB docks with multiple
displays attached regularly. When I wake my notebook from sleep, it has to
redetect the displays (which is fine), but in this process, it's impossible for
me to unlock my screen using a password. The issue is that when a new display
is connected, the input focus switches from one display to another and since
the password fields aren't synced across displays, I enter half my password on
one screen and half my display on another. Sometimes it also seems that keys
are registered multiple times when a new display is recognized while entering
the password.
This is really annoying as I have to wait up to 30 seconds until all displays
are correctly identified and configured, until I can unlock my screen.
STEPS TO REPRODUCE
0. set long password
1. Lock screen with no external display connected
2. (maybe let notebook go to sleep? Should not be relevant)
3. connect external display
4. try to enter password while display is being recognized
5. observe
OBSERVED RESULT
Password parts are entered on different screens, sometimes keys are registered
multiple times and it's impossible to unlock the screen using a password
EXPECTED RESULT
I can enter the password and unlock the screen while external displays are
recognized/configured
SOFTWARE/OS VERSIONS
Windows:
macOS:
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: openSUSE Tumbleweed
KDE Plasma Version: 6.5.3
KDE Frameworks Version: 6.19.0
Qt Version: 6.10.0
ADDITIONAL INFORMATION
I see two possible solutions:
a) keep the input focus on one screen during password input when other displays
are connected
b) sync the password across screens, so it doesn't matter if the focus switches
The second solution might be more tricky as I don't knwo what happens when the
focus switches while keys are pressed. But in general: Why can I enter
different passwords on different screens anyway? Why would I want to do that?
If helpful, I can attach a video showing the issue, but it should hopefully be
fairly easy to reproduce :)
