[linux-help] Re: X has ghosts and literally giving me a headache

[Clint Brubakken <cabrubak@xxxxxxx>]

Thats what it got by probing my monitor. It will only do 1280x1024 at
60hz. Its a samtron 77V. The video card is a Sis 8meg onboard. 

It doesn't give the headache it used to, but I still have the ghosts (2
mostly white lines that follow the cursor)

I haven't restarted x since I made changes with the shadow, so that
might fix that.

Is the a way to tell what refresh rate its using? It is capable to do
1024x768@85 hz, with windows, but how to do that with X?
