Find out the actual refresh rates and plug them into
XF86Config-4. You can probably find this information in your
user manual for the device, or you can check the
manufacturer's or vendor's web site.





I searched the refresh rate for my monitor and it tells me the max
resolution and refresh rate is 1028*1024 I really do not understand
how to convert this into Xserver config.

Below is my xserverconfig file but my monitor is using 1028*768 as
resolution and some bad refresh rate which hurts my eyes.

Can any of you help me please?

What command I can use so that I can find out my graphic card info and
therefore find the right driver for it? dpkg-reconfigure
xserver-xfree86 give me a long list of available drivers, how can I
know what should I use please?

Thanks a lot!
Rocky
Keep correspondence on the list for your benefit and the benefit of others.
The predefined modes such as 1024*768 depend upon correct horizontal sync rate and vertical refresh rate. See "man XF86Config-4"; in your XF86Config-4, HorizSync is 65-70, and VertRefresh is 80-85. Neither of these may be correct; check them.
You get the correct horizontal and vertical refresh rates from your monitor manual. Without them X is unable to correctly determine which video modes work on your monitor.
