Quick Tip: How to Enable ATI Catalyst Driver (fglrx) in Ubuntu 11.04 and Take Care of Screen Lag

A new version of ATI Catalyst driver (fglrx) has been made available in Ubuntu 11.04 which is compatible with latest 2.6.38 kernel and xserver 1.10.

Those who want to install the proprietary driver in Natty for better 3D acceleration, follow these three quick and easy steps:
  • Fully update your system with all the latest unity and compiz packages.
  • Install proprietary drivers from jockey as shown in the screenshot below:
  • Install Compiz Config Settings Manager from software center. Go to OpenGL plugin and disable Sync to Vblank to take care of any screen lag you may observe in unity or classic desktop.
  • Additional Step: If the problem does not get solved even after turning off vblank, disable 'Tear Free' option and completely turn off vsync in Catalyst Control Center as shown in the screenshots below:

That's it. Now you can use Unity without any lag and at full speed in Ubuntu 11.04.
