Screen & Monitor resolution

[babakan]

PCLOS. ATI x700, LG L1930B monitor.
I finally got ATI drivers to work but cannot get desired screen resolution. I have set it for 1280x960 but it is actually 1152x864 and thats what the monitor itself shows. My settings (XFdrake) are for 1280x960.
Interestingly (may not be important) KDE Control Center-Peripherals-Display shows 1152x864 @70hz. In KDE that is the max res listed. Why doesn't KDE list what is in the mode?

Have you tried the native resolution of 1280x1024? Your screen isn't a wide one and should be able to do 1280x1024 according to manufacturer's data.

You would think so, but note the modes created by the ATI driver install do not include it. I posted that question on the PCLOS forum and Texstar (Mr PCLOS) that he also found only 1280x960 works with the ATI driver. Actually I tried it anyway and it crashes X. I would be happy with 1280x960 if I could actually get it. I think it may not be working because at that res my monitor can only go at 70Hz, seems like it may be at 75. So, the question is how do you set the monitor update rate. Doesn't seem to be anything in xorg.conf. ATI video boards are not happy in linux. I may just give up and get an Nvidia.
