  In extreme circumstances, we may ask you to use the crashhandler plugin from [[http://git.compiz.org/compiz/plugins/crashhandler|git]] and enable that in ccsm.
  
+ If you are experiencing a freeze, but can still use Ctrl-Alt-F1 to get to TTY1, you can use gdb to connect to the running compiz process, and get a backtrace. This will be invaluable information for us to debug your issue. To attach to the running process switch to TTY1, and follow these instructions.
+ {{{
+ $ sudo gdb compiz `pgrep compiz`
+ 
+ (gdb) set logging file unity.log
+ (gdb) set logging on
+ (gdb) bt full
+ 
+ [ then CTRL-D or re-run compiz to continue working ]
+ 
+ (gdb) run
+ }}}
