Using Xconfigurator and selecting monitor option; Compaq QVISION172, results in X windows failing to start. This appears to be a fault in the horizontal frquency entered into XF86Config by Xconfigurator. This is set as 31. This is far to low for any working monitor modes. Compaq's web site (I don't have a manual) sas the figure is actually 31.5-110. If I manually edit XF86Congig to this value X works.
should be fixed in next Xconfigurator, which will be in next Raw Hide release.
