Bug ID: 403255
Summary: Screenlock prevented by kdialog on read-only
filesystem
Product: kscreenlocker
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: l-softw...@lausen.nl
CC: bhus...@gmail.com
Target Milestone: ---
SUMMARY If .config/kscreenlocker_greetrc is not writable (eg. due to emergency
remount of the partition as read-only) and the user attempts to lock the
screen, a dialogue containing: 'Configuration file
"/home/leonard/.config/kscreenlocker_greetrc" not writable. Please contact your
system administrator.' will popup and the system will freeze. It is not
possible to close the dialog, neither does the lock screen show up.
Logging in on tty and issuing `killall kdialog` closes the dialog. Switching
back to X session, the lock screen shows up. Unlocking the system works fine.
STEPS TO REPRODUCE
1. mount -o remount,ro /home
2. Lock screen
OBSERVED RESULT
System hangs with dialog message 'Configuration file
"/home/leonard/.config/kscreenlocker_greetrc" not writable. Please contact your
system administrator.' open.
EXPECTED RESULT
Screen is locked. Dialog with warning may/should be opened, but should not
block screen locking process and cause system hang.
