Public bug reported:
Using 14.04 (not a clean install, but upgraded from 13.10) in an
inspiron 1525: when the lid is closed the computer goes to sleep, even
though I have configured it in the settings to "do nothing" when closing
the lid. Then the screen fails to wake up after the lid is oppened
again. The OS seems to wake up since I can see the HDD/bluetooth led
flashing, but the screen remains black. Behaviour is the same regardless
of if the system is configured to lock after closing the lid or not, or
if asked to requiere password after waking from lock or not. The only
way to proceed from there is to reboot the computer.
