Bug ID: 457742
Summary: Plasmashell crashes when unlocking
Product: plasmashell
Version: 5.25.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: macr...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.25.4)
Qt Version: 5.15.5
Frameworks Version: 5.96.0
Operating System: Linux 5.18.16-200.fc36.x86_64 x86_64
Windowing System: X11
Distribution: "Fedora release 36 (Thirty Six)"
DrKonqi: 5.25.4 [KCrashBackend]
-- Information about the crash:
Currently I have 4 monitors connected to my system, 3 at my desk and one
located a distance away. They are set up such that when my right-most monitor
is turned on, the three on my desk are enabled while the remote monitor is
disabled and vice-versa. I am currently using X11 rather than Wayland despite
using Fedora36 as any attempts to use wayland result in a much worse crash. To
reproduce the crash all I need to do is lock the computer and leave it for long
enough for the screens to go into sleep mode. Upon attempting to log in I will
rarely be able to log in successfully, but more often than not I am presented
with a button that says "
unlock" but does nothing when pressed. To get logged in I then need to manually
turn off the right-most screen and then turn it on again, which allows me to
attempt to log in again on a different monitor, however this time it will let
me in. Whether or not I log in on the first time I will see a notification from
drkonqi that plasmashell has crashed, but the vast majority of the time drkonqi
closes itself before I can save any information and fails to save any reference
of the crash. It appears as though drkonqi closing coincides with plasmashell
relaunching, but with this most recent crash drkonqi did not close. If I
attempt to use wayland the system becomes unstable and I must switch to a
terminal session and forcefully close any running programs on the session that
has frozen before rebooting the system. All of my monitors are from different
manufactureres, with my desk screens being manufactured by Dell, acer, and
samsug, in order, left to right, while my leftmost screen is rotated 90 degrees
to the left. The screens also have different resolutions, from left to right
being 1080, 1440, and 2160. I am currently using an AMD Radeon VII as a GPU and
have the 3 desktop monitors connected via display port. I attempted to ensure
that all relevant debug symbols were installed when generating the trace, but
still received a warning that some were missing, but I would be happy to
provide any other information if necessary.
The crash can be reproduced every time.
