[Solved] Xandros: can't get the system to 100hz@1024*768


Hello

I have recently installed Xandros 3 and I am rather new to linux and I have a disturbing problem.
My monitor (Samtron 96p) and my graphic card (Creative Geforce 4 mx 420) seems to be correctly installed. When I under Configure--settings--advanced sets 100 Hz it still doesn't goes higher than 85 Hz (according to my OSD and my eyes). I know it is possible to get to 100hz while it works in mandrake and windows xp.
Anyone who knows what to change in the /etc/X11/xorg.conf (see below) or if I shall change something else?

/Henrik Andersson

Hi,

Hmmm - of course what you should have done is to save a copy of your X config off Mandrake and then you could compare it with the Xandros one. It would then be possible as you say to edit this file and get the desired refresh rate.

Try upping the limits for HorizSync and/or VertRefresh in the Monitor section. In fact, before you do that comment them out altogether as Xorg should be able to query them from the monitor.

With older monitors using unsuitable values can damage the hardware, but newer monitors will detect out-of-range frequencies and just show an error.

It is also woth reading the /var/log/Xorg.0.log - as X boots it attempts to explain how it is configuring the hardware, and what refresh rates and resultions it determines will work based on the config and hardware probing.

Thank you for the hint, I plugged in my Mandrake harddisk, copied my configuration file there and I copied a modeline for 1024*768 and now it works perfectly
