Package: gdm3
Version: 3.14.1-7
Severity: important

Dear Maintainer,

   * What led up to the situation?

I locked the computer and when I came back the system would not update the
screen.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

The cursor can be moved around and I can interact with the system (log in,
click buttons etc) but the GUI isn't updated.
If I switch to tty1 and back I can see the effects of my previous interactions
but again no new interactions will update the screen.
A restart of gdm3 solved the problem. This only happens the first time I lock
the screen after a boot. Not sure if it happens every boot...

   * What was the outcome of this action?

The GUI seems frozen. No interactions or changes are displayed.

   * What outcome did you expect instead?

The GUI updates as it should.

-----------------------------


* Extract from syslog:

I was only away from the computer for 10-15 minutes so the error should be
somewhere here if it was recorded.
