monitor rafresh rate

[vultureanu]

I've already installed linux Slackware 10. Please, tell me, how can I change refresh rate for my monitor from 61Hz to 85Hz...because XF86Config no longer exist and in Control Center Modules I can't select other refresh rate. My monitor supports 1024x768 with 85Hz.

XF86Config is now xorg.conf in Slack10.

This is my xorg.conf file. So ..were should I change the refresh rate?

[Daedrus]

What monitor are you using and what video card do you have?
By the looks of your xorg.conf file you don't have monitor specified (i don't think you have to) and you are using a generic vesa driver which could be restricting your refresh rate. The setting you are looking for is VertRefresh which is currently set to 40-90. You will also what to check your monitors setting for Horizontal Sync Rate to make sure that what is set in the conf file is correct for your monitor.

My monitor is an Likom ..and supports 1024x768 with 85Hz. My VGA card is Ati onboard with 4M RAM. In Slackware 9.1, in X I choose 17'' Philips Monitor and ATI VGA card....but here ..I can't choose anything. My monitor is set in 1024x768 with 61Hz.
In xorg.conf....I don't no where I should specify that specifications.

What's your monitor make/model? Running a search on http://google.com/linux you should be able to find the refresh rates for that monitor to be entered into the xorg.conf
