Description of Problem: X only sets the i810 to 60Hz refresh on a Dell Optiplex GX110. I know it is capable of higher refresh, b/c windows can do so. Version-Release number of selected component (if applicable): XFree86-4.2.0-6.52 on Skipjack-BETA2 How Reproducible: See below... Steps to Reproduce: 1. Run XConfigurator 2. Select 'custom' monitor, and highest refresh rates possible 3. Start X server Actual Results: Only get 60Hz refresh. Expected Results: Additional Information:
XFree86 comes with a set of VESA GTF standard modelines which are used by all hardware. The X server and drivers automatically choose modelines with the highest refresh rate for the monitor, and video mode, etc. However, this is not necessarily the highest refresh rate the hardware can _do_, but rather the highest refresh rate that X has built in for a given mode. If you want to use refresh rates beyond what XFree86 has built in, you need to generate the modelines yourself and add them to the X config file, the details of which are beyond the scope of what bugzilla is for. You can try http://xtimings.sf.net for creating new modelines. For the record, Windows can do higher refresh rates because it is not something to do with the operating system, but with the video drivers, and the Windows video drivers come with higher refresh rate modelines than X does.
