I did a fresh install of Ubuntu Gutsy Gibbon Tribe 3 on my laptop on Saturday. It has ATI Mobility Radeon X1600 graphics card. I had problem with the Live CD as usual. The X server didn’t work. I had to use the safe graphics mode in Live CD to get it to work. I then installed Ubuntu from the Live CD. The installation went fine, but Ubuntu didn’t install the proprietary driver for ATI card by default. I had to manually install and reconfigure my xserver. ATI support really sucks in Linux. Gutsy is slightly buggy, but it didn’t prevent me from doing the regular work.
