Can't get anything better than 800x600 resolution

Is is just a typo that you have "1024 x768" with a space between "1024"
and the "x"?  If not, then remove that space.  Also, browse through
/var/log/Xorg.0.log and it should tell you why it rejects a particular
resolution.  Here is a tiny snip from my Xorg.0.log file as an example:

(II) NV(0): Not using default mode "512x384" (bad mode clock/interlace/doublescan)
(II) NV(0): Not using default mode "1280x960" (hsync out of range)
(II) NV(0): Not using default mode "640x480" (hsync out of range)
<snip>
(WW) (1400x1050,Monitor0) mode clock 122MHz exceeds DDC maximum 110MHz
<snip>
(II) NV(0): Not using default mode "1152x864" (width too large for virtual size)
(II) NV(0): Not using default mode "1152x768" (width too large for virtual size)
(--) NV(0): Virtual size is 1024x768 (pitch 1024)
(**) NV(0): *Default mode "1024x768": 94.5 MHz, 68.7 kHz, 85.0 Hz

And there are a lot more lines than this, and you can see that there are
various reasons why X might not allow a particular resolution or
setting.
