One of the reasons that I wanted to upgrade to Ubuntu 7.10 before it was released was so that I could have a play with the new developments in compiz. It was therefore more than a little disappointing to discover that it did not work. When I tried to enable desktop effects, it would simply state that it could not, and would revert back to metacity.
At first, I was a little annoyed as I could not even see any error message as to why this had failed. Finally, for another reason, I started gnome-settings from the command line. When I then selected the appearance tool, and tried to turn on desktop effects, some useful information scrolled up the screen.
It would appear that by default, compiz checks that the graphics card has at least 64 MB or RAM before it will allow compiz to start. No doubt this is done for a good reason, but this does not help me with my 32 MB graphics card in my laptop.
A little bit of googling and I discover that compiz in Ubuntu has a wrapper script called
/usr/bin/compiz A quick look in here and it is easy to see where the check for the RAM is done. I dropped the limit to 32 MB and tried again. Yay! Wobbly windows 🙂
Now all I need to do is find out how to configure compiz ….
