Hi. When I tried to run Mandriva 2008 form live-cd, I've 'met' a bug. It's description and solution is described in it's errata:
Few users told us about black screen appearance while loading desktop using ATI Radeon.Solution: Erase following lines from /etc/X11/xorg.conf:

# TV fullscreen mode or DVD fullscreen output.
# 768x576 @ 79 Hz, 50 kHz hsync
ModeLine "768x576" 50.00 768 832 846 1000 576 590 595 630

# 768x576 @ 100 Hz, 61.6 kHz hsync
ModeLine "768x576" 63.07 768 800 960 1024 576 578 590 616
And the question is, how to do it? I mean, how to find this file. It couldn't be done by exploring cd from windows.
Regards
