[Bug 1042989] Re: X server hung with black screen after long inactivity

 

Bernie,

What graphics card/driver do you use?

Also, if compiz is hung then a stack trace of the compiz process would
be very helpful. To do this...

0. Download and keep a copy of the attached dstack script handy in your home directory.
Then when the hang occurs;
1. Switch to a VT (Ctrl+Alt+F1) and log in.
2. sudo ./dstack compiz > compizhang.txt
3. Kill/restart/recover any way you like, e.g.  sudo restart lightdm
4. Attach compizhang.txt to this bug.
