The chip is a Neomagic but the principle may still apply to other
situations. The maximum color depth is detected first and then the
maximum resolution is determined. If the default depth is decreased in
/etc/x11/xorg.conf, then higher screen resolutions may become available
in limited-memory vid
I have a Dell Latitude Cpi D300XT that was stuck in 800x600 mode when
running XUbuntu 7.10. Analysis of the log showed that the video section
was reporting a default graphic depth of 24 bits, making the card run
out of memory at resolutions above 800x600. The fix is very simple:
In /etc/x11/xorg
