Fix Compiz memory leak on Ubuntu Jaunty Jackalope 9.04 with Intel graphic cards
There's a memory leak in Compiz when you are using UXA mode for Intel graphic cards driver. After a few hours, Compiz eats all available memory and the system crash.
To prevent this you must change some Compiz startup options :
Open a console and type
sudo vim /usr/bin/compiz
Round line 74 replace the line ...
COMPIZ_OPTIONS="--ignore-desktop-hints --replace"
... by this one
COMPIZ_OPTIONS="--replace --sm-disable --ignore-desktop-hints ccp --indirect-rendering"
This will fix Compiz memory leak, but there seams to be a problem about rendering transparent windows when intirect rendering is activated.
I didn't notice this problem on my configuration. I followed tutorial in ticket Drastically improve Intel graphics performance under Ubuntu Jackalope 9.04 before, this might help... or not.
