Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

From 3 days ago, I find screen is sometimes black after waking up from suspend and lock screen. But sometimes it is OK.

I have read all posts about 'black screen' in AskUbuntu site, but those do NOT help me .

I use i5-2450M and Nvidia optimus video card GT 550M ubuntu 12.04.2 amd64 arch.

At that time , I have to use Alt SysRq K to kill X, and login again. This is so boring.

How to do with it ? Thanks
