I upgraded from 10.10 to 11.04,My pc hangs many times.
What does hung mean here?
My mouse pointer is stuck and I can't use shortcut keys,and I can't run Alt+F2 and incase I hear music,last song sequence is being repeated again and again.
When does MY pc hung?
1.While hearing to songs in Rhythm Box.
2.While using Firefox 4.
I am using Unity,how can I fix this problem?
