152049 2003-06-12 09:22:00 I'm getting the hang of some stuff in Linux, but one thing is really getting to me :). I've got really sensitive eyes and the monitor flickering away at 65hz or whatever it's on hurts them, so I'd be keen to learn how to up the refresh rate in Linux to something closer to the 85Hz I've got it running in XP.

Any takers?

Mike.

In the mandrake control panel, goto hardware, configure monitor. I just use plug & play.

If that doesn't work, you can set the monitor manually by editing /etc/X11/XF86Config-4.

Under the monitor section, you will need to set the frequency ranges of your monitor. For most 17" screens (1024x768 @ 85Hz) it will look like:

HorizSync 30-70
VertRefresh 50-160

If I set that VertRefresh to be, say, 85-160 does that mean it'll use a minimum of 85Hz? or are the number unrelated? :)

I've never tried, but I think its related. When its setup correctly, X will work out the best refresh rate it can do automagically.


If its giving you trouble, have a look in /var/log/XFree86.0.log, it will tell you why its doing/not doing things.

And it should also mention what it detects about your monitor (if it supports it). [Wonders why it doesn't use it automatically...].
