I tried Ubuntu on Acer Ferrari, it worked like charm. But when I tried to enable compiz fusion or so called desktop effects it wasn’t that straight. I would say it was a problem because every howto I found about enabling compiz fusion or desktop effects was missing the very basic requirement for desktop effect. That is xserver-xgl package, this package needs to be installed before you can enable desktop effects on your Ubuntu desktop. Use the command below to enable xgl on your Ubuntu.
Note: From Ubuntu 7.10 you only have to install the package, the xgl server will be automatically enabled.
apt-get install xserver-xgl
There wasn’t any other problem, the fglrx drivers from ubuntu repository worked fine for me. I have ATI Mobility Radeon X1600 256MB that cam with my laptop. Need to check the rest of features, like camera, bluetooth mouse and connectivity my Nokia E50. I think enough for now.
