apport ist enabled and I uncommented in /etc/gdm3/custom :
#Additionally lets the X server dump core if it crashes
Enable=true
After reboot i reproduced the crash. I login and logout. Then I login with
another user and logout.
After then i get a purple screen, when i try to login . But in /var/c
Public bug reported:
gdm3 sometimes crash after logout and login again.
I get a purple screen, a mouse cursor and nothing more.
After crash, the second login always works.
