I have now upgraded to ubuntu 8.10 the other day, the install went with out any problems. The only issue that I have is with my GPU which is a GeForce4 MX 420 and that required me to activate the nVidia proprietary driver version 96. This will enable the 3D acceleration to work.
I’m not going to do a review as this will have been done by many others and with a lot more in depth analysis. But my overall impression is good with some nice extras. I do like the tab’s in nautilus 2.24.1. It’s not amazing but worth the upgrade or install.
