this should be OK...my sync rates are...

this seems to be a problem for a 19" LCD... I have set only...
Modes "1280x1024"
on this last line.

perhaps just make a backup copy of /etc/X11/xorg.conf and edit the
original. Many LCD monitors aren't capable of running at resolutions
other than the one the default and I would think that the proper
resolution for a 19" LCD is 1280x1024
I can do that, but I've got the monitor manual in my hand, and it lists
the following display modes for the Starlogic 19"
Resolution Horizontal Freq Vertical Frequency
640x350 31.475 70.100
640x480 31.469 59.940
640x480 37.500 75.000
720x400 31.469 70.087
800x600 37.879 60.317
800x600 46.875 75.000
1024x768 48.363 60.004
1024x768 60.023 75.029
1280x1024 63.981 60.020
1280x1024 79.978 75.024
Some people on the test list seemed to have success when they commented
out the vertical and horizontal sync lines, which made their systems
perform better with DDC detection (whatever that is specifically)
you might want to try commenting out the lines and giving it a try by
restarting the X server after editing the file.
Also, to get useful information from the /var/log/Xorg.0.log file, you
need to copy this information somewhere before you start the server
again. This log is written new each time the server is started. You
might be able to get helpful information from the
/var/log/Xorg.0.log.old file which will be the previous session before
your working GUI. You might want to grab that log file.
The safest way to work out X problems is to start or telinit the system
into runlevel 3 and then log into the terminal as a regular user and
start X with the startx script.
If all else fails, you might try the ati-fg?? driver from a repo
somewhere. Of course chances are the upstream source for the open driver
needs to be relayed that there is a problem. If you can get a log for X
with what is failing, it might help correct the problem with the failure
information.

Well fix that in the next (upgrade, update, patch release, service pack).
