Ubuntu 11.04 Black Screen
I've just installed Ubuntu 11.04 (fresh install) and encountered a problem. After I choose to boot Ubuntu from GRUB, the screen turns black. I can tell it's booting from the sound it makes when it enters the user log in screen, though. Well, sometimes it works just fine, but mostly it goes black screen and need to restart several times to get it work.
Anybody knows what can I do to fix this?
I tried to use the recovery mode, but the screen goes black when it's loading into the recovery mode. Same thing happened with the liveCD when I decided to reinstall it completely (it didn't happen when I installed it yesterday).
I think there might be something wrong with my graphic card. I'm using Acer Aspire 4736 with Intel GMA 4500MHD.
Any ideas on what's wrong here and how to fix it?
