Bug ID: 466586
Summary: System tray disappeared after screen size change,
reboot did not recover
Classification: Plasma
Product: plasmashell
Version: 5.24.7
Platform: Ubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: System Tray
Assignee: plasma-b...@kde.org
Reporter: jamshar...@zoho.com
CC: mate...@gmail.com
Target Milestone: 1.0
OBSERVED BEHAVIOR
The system tray disappeared (all of it) -- including, no way to open the
application-start menu. A reboot did not fix it.
Eventually I got it back by finding online advice (on my phone... couldn't open
any apps, so, no browser on the computer) to ctrl-alt-F2 out, stop the display
manager service, blast the cache and plasma config away and reboot.
(https://forum.manjaro.org/t/applications-icon-missing-in-system-tray/109433/13)
What was happening at that time: I was trying to mirror the display on a
projector. The projector wasn't responding well to a higher display resolution,
so I went down to 1024x768 (which I had used successfully on an older machine
in the past). I didn't notice the tray was gone at first, but after closing a
couple of app windows, the tray was gone, and the app-start menu was not
responding to the Super key.
EXPECTED BEHAVIOR
HDMI connection + display resolution change should not bork the app menu and
system tray.
USER IMPACT:
I was in a classroom with 50 students waiting for class to start, and unable to
open any apps. In 12+ years of using Linux as my main operating system, this
was my absolute worst experience.
One suggestion:
The app-start menu is critical. Without it, the only thing you can do is
ctrl-alt-F2 to the console: no browser, no terminal, no system settings, not
even logout / reboot. So it would be good to have some sort of failsafe -- even
a prompt such as "KDE has detected a problem with cache and configuration
files, clear and restart the desktop?" would be dramatically better than the
"your system can't do anything and you had better hope you can find the answer
on your phone" situation I was in.
I left the bug as normal priority, but... app-start menu failures are
catastrophic, rendering your computer into a brick.
