Fix Intel Graphics on Ubuntu 9.04 - Enabling Visual Effects
Tue June 16th, 2009 - By Resu
When I installed Ubuntu 9.04, I noticed something missing that I've been accustomed to for some time now; those cool Compiz effects were gone. I noticed this when I ran Ubuntu from the Live CD but I thought maybe it was a bug in the Live CD or maybe my CD was scratched. Well the problem actually ended up not being a problem at all. It was actually because of a "safety precaution" added by the developers of Ubuntu.
The developers of Ubuntu decided to blacklist the Intel graphics cards from using Compiz as there seems to be a couple of hiccups that needs to be fixed such as some random freezes and hangs. Even though the team is going to release an update that will remove the blacklist when things are all fixed, I know people are still interested in removing the blacklist themselves manually.
Well no worries. Removing the blacklist is dead simple, but remember; there's a blacklist for a reason. If you still wish to remove the blacklist then copy the text below in the Terminal:
Now you need to enable the visual effects by right clicking on your desktop, clicking "Change Desktop Background" in the menu, going to the "Visual Effects" tab and choosing either normal or extra visual effects.mkdir -p ~/.config/compiz/ && echo SKIP_CHECKS=yes >> ~/.config/compiz/compiz-manager
Removing the blacklist has not caused any crashes on my computer but if it has caused problems on your computer or you simply wish to wait for the proper update to remove the blacklist then re-enabling the blacklist is also very simple to do. Just type in the text below in the Terminal:
Remember to disable visual effects before doing this as it may cause some problems.rm -rf ~/.config/compiz/
