can't change refresh rates in Kde
 

hello!
i've just installed Slackware 13.37 but there seems to be an issue.
i can't change my refersh rates(i want to change ir from 75 to 85 KHZwhich are the only options) as each time i change 85 in KDE from system settings works until i restart X then it goes to the previous setting which is 75.my xorg.conf looks like this

i've tried modifying xorg.conf putting minimum vertical sync to 85 but the same issue
i could really use some ideas
thanks in advance!

You need to google your display modline at 85hz, then add Modeline into xorg.conf monitor section.

If this is an LCD monitor then don't bother as the refresh rate is now meaningless and has no effect on the displayed output.

i've added modeline in the monitor section but the 85 that this gives me still is not the 85 that i can change when in X
the same happens even if i go to xfce

p.s is not an lcd and it's pretty old from 2003 i think

Look in /var/log/Xorg.0.log to find the mode information that you need.
