Bug ID: 454777
Summary: Screen locking no longer works
Product: kscreenlocker
Version: 5.24.90
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: bizy...@zoho.com
CC: bhus...@gmail.com
Target Milestone: ---
SUMMARY
I am currently using openSUSE Leap 15.3 with KDE repositories, so I installed
updates for Plasma 5.24.90. After the update, I realized that kwin and a bunch
of other packages are still at 5.24.5, but things worked smoothly regardless,
Then, the day before yesterday I got the missing updates to 5.24.90:
gmenudbusmenuproxy
layer-shell-qt5
libKScreenLocker5
plasma5-integration-plugin
xembedsniproxy
xdg-desktop-portal-kde
libKF5Screen7
libkscreen2-plugin
kwayland-integration
kscreenlocker
kwin5
plasma5-workspace-libs
plasma5-workspace
plasma5-session(-wayland)
(note that I use X11)
I installed those and made no other tweaks. Since then, whenever I try to lock
my screen (or it locks automatically), instead of the lock screen I get the
"switch to TTY and unlock with loginctl" message :(
There are some QML errors in journalctl logs:
https://paste.opensuse.org/99027736
However, `/usr/lib/kscreenlocker_greet --testing` works as I'd expect.
Even `/usr/lib/kscreenlocker_greet` (without arguments) works and shows a
proper lock screen.
As instructed in openSUSE's KDE channel, I also did `strace -fetrace=execve -p
$(pidof ksmserver)`: https://paste.opensuse.org/78537251 (this output is from 1
lock attempt). Quoting fvogt: "The strace shows that execve succeeded, but at
some point it fails with 127 (file not found)". I have no clue what could be
missing…
As a workaround, I have disabled the lock screen completely for now.
STEPS TO REPRODUCE
1. Trigger the lock screen with a timer or a keyboard shortcut
OBSERVED RESULT
"The screen locker is broken and unlocking is not possible anymore. In order to
unlock switch to a virtual terminal…"
EXPECTED RESULT
My lovely Breeze-themed lock screen, as usual.
