Bug#939861: Session crashes after unlocking if the screen size has changed while locked
Package: xfce4-session
Version: 4.12.1-6
Severity: normal
Hello,
thank you for maintaining xfce! I am not sure if this is an issue in
xfce4-session or lightdm/light-locker, feel free to reassign. I also
didn't change the severity, although it could potentially be higher, as
this causes data loss.
What happens is this:
- I lock the screen, either explicitly or by closing the lid /
suspending
- I unplug or plug my external screen
- I [resume and] get the lightdm greeter
- I enter my username/password to unlock
- there's a flicker, and I get back to the greeter. The session
has died
- I enter my username/password and I find an empty session. All my open
windows have died, all my unsaved work is lost.
It doesn't always happen, but it happens often when there's been a
change in the screen geometry while the session was locked, and never
when the screen geometry stays the same.
When it happens, one can imagine it's extremely frustrating.
Enrico
