Xserver question - why VESA considers monitor Virtual size is 800x600 ???

[Hetz Ben Hamo]

Hi Lev,

Unless this is a last resort, I really recommend *NOT* to use the VESA
driver. Vesa used the least of your grpahics chip capabilities, NO
graphics acceleration, no nothing,

Any native driver for your graphics chip would do a better job of
allocating memory (and not giving you only 64MB RAM for your chip) and
will detect all the resolutions. VESA most of the time don't know much
about those resolutions because it's trying to go "wild" with 24 bit
colors and for VESA, thats what you can get unless you fiddle with
many parameters in xorg.conf file.

Your monitor can supports multiple resolutions as shown by your log,
but VESA is too dumb. Use the correct driver (which chip do you have?
if you can tell me, I'll be happy to tell you which driver to use) and
it should show all the fancy stuff.

Thanks,
Hetz
