Bug Description
I downloaded ubuntu 5.10 live cd for i386 (and burn it correctly). when booting
the CD everything goes well, the whole boot sequence seems ok. I can see boot
sequence happening (loading drivers etc.. in text mode). then it changes to
graphics mode and I see that sequence going well too...
until in final stage... (maybe when starting X?) it chooses some sort of wrong
video settings (or driver) and the screen display is goes haywire. you know the
situation when you feed a monitor with wrong sync signal and wrong timings
etc... each true line of display is a fraction of visual line in screen.. and
then the next line follows starting from the middle of previous line..
everything works well under windows 2000 (so i don't think it is a hw problem).
my configuration is:
motherboard: asrock k7vt4a pro (1.0x)
video: radeon 7000 series
monitor: nokia 445XPro (the old reliable 21")

please attach /var/log/Xorg.0.log and /etc/X11/xorg.conf. if you have HorizSync
and VertRefresh entries in your xorg.conf, does deleting them help? what's the
output of sudo ddcprobe?
