I recently converted my wife's PC to Ubuntu (I tried Debian, and wanted
Firefox instead of iceweasel (also had troubles getting flash player to
work). Debian immediately had high res (standard off-the-shelf Intel P3
mobo with built-in video). But Ubuntu only gave me 800x600 max res. One
thing I learned in years past was to manually enter the horizontal and
vertical refresh rates of the MONITOR into the X setup config (xf88config
back then, xorg.conf now).
In doing this, and rebooting that PC, Ubuntu magically discovered a new
range of higher resolutions.
Same in configuring Linux, over time, for my ol' Dell CRT (17 inch)
monitor. Unless I give Linux the specific frequency ranges, it can't
display proper high res for me.
Again, I'm not entered the rates of the card, but the *monitor*. You may
still need the driver for the card to get Linux properly talking to it,
too.
Hope that helps.
