Bug ID: 484592
Summary: External display rendered unusable due to
misconfiguration
Classification: Applications
Product: systemsettings
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: shaloksha...@protonmail.ch
Target Milestone: ---
SUMMARY
I managed to setup the external TV in a way, that it is completely unusable
from this installation.
There is currently no GUI way, to restore its functionality as external
display.
I suggest to implement a functionality, that allows to configure previous
output devices even when they are not connected. (Or at least restore their
settings)
STEPS TO REPRODUCE
1. Connect an external display
2. Choose an incompatible resolution (2560x1440)
3. Switch to it as the only output source (Fn+F7 in my case)
I also set the TV as the primary display in the KCM, idk if thats important to
replicate.
OBSERVED RESULT
Both devices stay black, once the TV is connected.
EXPECTED RESULT
Either the OS recognizing and accommodating for the issue, or providing an
option to reset the ill setting manually before the connection happens. ab
Operating System: NixOS 24.05
KDE Plasma Version: 6.0.2
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
Kernel Version: 6.6.22 (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 5800U with Radeon Graphics
Memory: 13,5 GiB of RAM
Graphics Processor: AMD Radeon Graphics
ADDITIONAL INFORMATION
I like to add, that the chosen resolution is not only made available by the
KCM, it is also a theoretically compatible format (16:9 on this LG E9)
So this can happen easily to common users.
I actually replicated that based on an issue,
that a friend of mine just experienced on Windows.
Seems like we can do better here ;)
