I have fresh install of Slackware 12.0 on a Compaq Presario w/celeron
2.7G processor. The display adapter is "Intel Corporation 82845G/GL"
and am running video driver "i810".
It works but xorg is stuck on 1152x768 and cannot budge from it;
Although I have no "1152x768" setting in xorg.conf
My monitor is not designed for 1152x768 and really needs a
conventional pixel size of 1024x768 or 800x600 (all images are too
narrow).
Here is the /etc/X11/xorg.conf file:

Load "dbe" # Double buffer extension

==============================
Control Center's "Display" configuration is no help; I tried changing
to 1024x768 or 800x600 several times and it just keeps reverting back
to 1152x768
