Just upgraded to the Beta considering Dapper 6.06 and the monitor refreash rate is set at 85 and needs to be 70 but unable to change this from the GUI. Where would I hack my condfig and set the refresh rate to 70? Looked in the xorg.conf and was unable to locate anything regarding the refresh rate.

In the Monitor section of xorg.conf, you can set the horizontal and vertical refresh rates for the X server. My Monitor section looks like this:

I added those lines and have tried a couple of different things. X starts but still unable to change the refresh rate.

The wonderful world of beta!

Post the whole xorg.conf file.

Been a while since having to dig around in the xorg.config. These use to be the problems of the past but then again this is the wonder world of beta!

I just upgraded from 5.10 to the new beta of Dapper. It really does not matter to me since I'll probably just download and install the Beta from scratch.

It looks like you just copied the refresh values from my example. You need to use the ones that actually apply to your monitor. Worst comes to worst, you can try changing the 85 to 70, and see if it's good enough, since that's what you said you needed.

I have a Samsung 796MB, it is necesary to install extra drivers to increase refresh rate? because I'm only able to pick 60 Hz, and my eyes are twisted.
