Mandriva 2006.0 beta 3 - update.
My X problem was cured by downloading the latest versions of xorg from cooker (6.9.0 cvs 20050825 - 15 days newer than the beta).
There are some other buglets for the GNOME user, but appart from that it's pretty good. I did try KDE, but it makes me ill. :-) Seriously, I can see why people like it, but it just doesn't do it for me. If I had to use it for a job, I wouldn't complain, and maybe I'd learn to like it.
