I recently upgraded to Hardy Heron from Feisty, I used Feisty for a while and it worked great.
Now my laptop is acting strange, the screen just goes off/black mostly when I try to shutdown and other random times. When I shutdown from the terminal and go back to the login screen then I can switch off normally and it works (mostly).
The laptop is quite old and it could be the hardware, but it never happened in Feisty.
This is driving me crazy, so any help would be appreciated.
