Ubuntu desktop occasionally got frozen.

Sat Mar 31 08:49:45 UTC 2012

hello Starry Sky,

Have you reported the bug as suggested by Brian Murray?
I faced some issues not exactly same as yours but have some similarities.

In my case usually mouse uses to freeze. Bug #896541, #896814

Please follow Brian advice and report a bug.

Thanks,

Regards,
KK
