That log shows X starting at 800x600, not 640x480.

This might be a BIOS parsing bug that's cropped up before.

My motherboard is an ASUS A8N SLI-Deluxe.

Comment 4 Tom Horsley 2006-09-15 21:39:55 EDT

This could be the same problem I reported to xorg:

https://bugs.freedesktop.org/show_bug.cgi?id=7243

Adding this option to xorg.conf radeon driver section fixed me up:

Option	    "MonitorLayout" "TMDS, NONE"

I still see this problem in FC6t3, but at least it now defaults to 800x600
instead of 640x480, so the screen is big enough to see the buttons during
a graphical install :-).

Comment 5 Pti-seb 2006-09-16 07:15:11 EDT

Thanks Tom, if i add your option in my xorg.conf, X starting at 1600*1200. It
very good but now I can't siwtch to 1280*1021 or 1024*768 resolutions ...

Comment 6 Adam Jackson 2006-10-03 11:49:33 EDT

This should be fixed as of xorg-x11-drv-ati 6.6.2-4 and later.  Please test and
reopen this bug if this is still an issue for you.  Thanks!
