linux can't be blamed for the lack of support of your ati card, amd is who you need to blame, it is also unsupported in windows since 2007 or 2008
"no i fix the mbr with win xp recovery console"
you are a power user, good
"since it can't even detect the correct drivers for my ati card."
we could help you with that if you gave us time, the right driver is x1950 and earlier, it covers cards from ati 9600(or 9800? can't remember) to the old ati radeon 7000, my current card, a ati radeon 9200 is also unsupported by ati/amd and i use the driver mentioned with very good results, in fact i don't have to configure it, just the resolution in my old samsung monitor which is very friendly with linux
the monitor on your case probably wasn't being detected properly, this is common with some video cards and older crt monitors with some refresh rates/resolutions, this happens on windows too, i say it because i work fixing pcs, mostly windows xp and vista
there is another way to enjoy linux, a virtual machine running inside windows, not the ideal way to use it but can give you ideas of what to expect on linux without installing it on your hard disk
i hope you can have better experiences with other distros and pclinux in future releases when running livecd or in a pc without other os so you can play with it and discover if you can find a use for it as many of us did many years ago
good luck with windows and remember that this forum is big and friendly, we sometimes help fix windows problems
and the sandbox is interesting
