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

[Hetz Ben Hamo]

Lev,

You didn't tell me which chipset do you use (I understand it's VIA,
but which VIA?), nor distribution that you use...

You can download a driver + docs if you know what chipset in your
board (lspci -v) at this site:
http://linux.via.com.tw/support/downloadFiles.action

You can use the forum here (http://www.tkarena.com/forums/via-arena/)
which I'm sure your question has been asked before.

Thanks,
Hetz
