[Bug 883783] [NEW] Xorg freeze on user change

 

Public bug reported:

Whenever a user locks the screen and another user tries to start a
session, the system first paints the white space of the password
textbox, but doesn't put the cursor inside. Therefor the password cannot
be typed. If the original user tries to return to work, the password
textbox isn't painted at all, so the first user is locked out. System
shutdown or restart don't work, so a hard reboot is needed.
