: After running the xf86config program, start X and stop it.
: Check out the output from the server on the console; in most case you can se
: the result of the servers scan through the XF86Config file, look for there
: - are all my resolution modes there, or has the server deleted anyone ?
: - if your 800x600 mode is deleted (its not deleted in the XF86Config
: file !), the server outputs the reason:
: o The vsyncfreq, vscanfreq or hscanfreq is out of the monitor selection
: you specified while running the xf86config program.
: o try out Interlace mode (On and Off).
: o A misproper frequency might be caused by a wrong dot-clock selection.
: Check out which dotclock the server chooses.
: Playing around with there settings might destroy your monitor. Most monitors are
: designed to work within certain sweepfrequences. If you go out of there specs,
: your guarantee will most certainly void.
: So your doing it at your own risk.

If you saved /etc/XF86config file, you can look for the entry at the bottom
of file. it is written under 'Screen sections' and the first configuation
points to your current screen driver & device.
you may can find a section called 'Driver "accel"' at the bottom.
play with it until you figure out how it works - make sure you have
a back-up copy of XF86Config. :)
Hope this helps,
