FIX: Screen Freezes After Closing the Lid in Ubuntu 11.04

My screen used to crash after closing the Laptop lid in Ubuntu 11.04 when I had set it as blank screen. After troubleshooting with power manager and Compiz Settings Manger, I finally fixed it with a little help from the Ubuntuforms. 

Here is how to Fix it:

  1. Install Compiz Settings Manager if haven’t installed it yet

sudo apt-get install compizconfig-settings-manager

2. Then go OpenGL plugin and Uncheck Sync to VBlank

Now my system doesn’t crash on closing the lid. Still got problems? Leave a comment below.
