X, since 4.4.0, tries to use DDC directly, but it handles the lack of frequency information akwardly. Modes are selected on the basis of these frequency ranges, either specified in the config or from DDC. When this information is not available from DDC, X tries to calculate this from the modes specified, resulting in frequencies which are close but not 100% equal to those specified in, in this case, the monitors manual. This explains the difference in values you might see. It seems that vesa is using 800x600@85Hz. > I'm about to give up using Linux because of a flickering screen. Firstly, to me, this translates as: "I don't care about this software one bit". Secondly, it is pretty close to blackmail. If this were irc, i would've stated "fine." and put you on ignore. Oh, by installing programs directly, you are going in against your package management system, which jeopardizes the long term survivability of your installation. You should be able to find (src-)rpms of 4.4.0. Luc Verhaegen. _______________________________________________ XFree86 mailing list XFree86@xxxxxxxxxxx http://XFree86.Org/mailman/listinfo/xfree86
