Blank Screen from Resume - Can still Login

view story

http://askubuntu.com – This may be a bug - I am testing Ubuntu 13.04 64bit. I have a HP Envy Extreme XT 13.3 When I suspend and resume, I have a blank screen. However I can still enter my password and then wait a few moments and press either of the screen brightness buttons and the screen wakes up. (HowTos)
