Only mouse is responsive after closing laptop lid

Question

I just upgraded to 11.04 and have been having this issue. I'm using the Unity interface, my card is an Intel GM965.

When I close my laptop lid I have it set to just blank screen. When I open the lid again, the mouse moves but nothing is responsive. I can switch to a terminal but when I switch back, the terminal text remains there with just the mouse moving again. I have to do a gdm restart to get Unity back.

Here's the relevant bug report:

Answer 2

Some possible fixes:

• Setting "OpenGL > Sync to VBlank [off]" in compiz settings manager (if you don't have it, sudo apt-get install compizconfig-settings-manager)
• killing gnome-power-manager (or remove it from start-up apps)
• Setting a screensaver

In my case though, none of those had any effect. I am still affected with the problem, but hopefully, since those worked for other users, they might work for you

ps: I know the question is old, but it appears in the first results of google when looking for the problem so I figured it should be answered
