I have a notebook running 7.10 (with updates) that uses 30Hz refresh instead of 60Hz.
- Averatec AB1020 ED2
- "intel" xorg driver

According to the log, X synthesizes a bunch of modlines. The first two have the right resolution for the panel (1280x768). The refresh rate differs: 29.7Hz for the first and 60Hz for the second.

I don't know how to get the driver to use the second refresh rate (the right one). As far as I can tell, modelines in the xorg.conf are ignored.

System: Administration: Screens and Graphics: at
Says "30 Hz" but offers "60 Hz". Changing this makes no difference. And it isn't changing xorg.conf -- what is it changing?

Is there a way to get X with the intel driver to use the correct refresh rate?
