Bug ID: 424979
Summary: [Enhancement] Create a notification if screen locker
was blocked in Xorg
Product: kscreenlocker
Version: unspecified
Platform: unspecified
OS: Linux
Status: REPORTED
Severity: wishlist
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: alexander.shchadi...@gmail.com
CC: bhus...@gmail.com
Target Milestone: ---
There is a known problem on Xorg with situations when some application prevents
locking screen; it was described as unfixable in Bug 383327.
Some related work was done here:
https://phabricator.kde.org/D20804
The number of screen locker attempts was increased to 3, also an "AboutToLock"
signal was introduced offering a possibility for 3rd-party apps to change their
behaviour right before screen lock attempt.
Plasma could launch a notification when screen locker fails due to Xorg
problems. At least it will serve as an explanation for a user who will get a
basic understanding of why a DE's security feature is malfunctioning. Text
variant: "Some application prevented screen locking".
A better text label might include an application's name, but I don't know if
this is technically possible. Currently log doesn't get further than "Could not
establish screen lock". Knowing an app's name will make some workarounds
possible, also in this case users might show it to developers and, who knows,
maybe somebody will implement "AboutToLock" monitoring in their code.
