Dear Maintainer,

I'll try to describe the issue as well as possible, even if I have no clue of
what happens.
After coming back to my workplace after a while, I see my screen locked. I am
prompted to type my password (the username is already filled). When the enter key is
pressed down, a kind of "re-init" takes place I see the login screen again, but
this time, I have to enter my username + password. I get logged in, but it is a
new session.. None of the applications left open before is active.

I tried to figure out what happens looking at the lightdm.log or
seat0-greeter.log files.

I configured xfce's power management section -> screen tab to:
- have an empty screen after 5 minutes
- put in standby after 10 minutes
- power off the screen after 15 minutes

My expectation is just to find my working session back after unlocking the
screen.
As a workaround, is there a way to disable screen lock with xfce ?

Thanks for your help

Hi, it looks like your session just crashed. Does this happen everytime or did
it happen only once? Did you get information from the logs?

Hi,

you are right, there is a crash of the xsession, but it happens _everytime_, so it is quite annoying. I did a diff of
the Xorg.0.log and the Xorg.0.log.old files and the difference is as follows:

Now, I guess the problem is not light-locker, but the function it calls... Maybe you can give me an advice of which
package has an issue, and where to get more help ?

Thanks a lot for your time,

Dimitri

Yup, it doesn't look like an issue in light-locker but rather in Xorg, not
sure exactly which package though.
