I was offline for the last few days, because of the problems I had with my computer.
I've managed to ruin my Linux.
I've tried, unsuccessfully, to install a newer version of Linux and a brand new 3D accelerated desktop environment. At my best effort I've succeeded in installing the newest version of Ubuntu Linux - 6.04 "Dapper Drake", but the 3D will have to wait. Too bad.
Will be gradually rebuilding my system.
