Yep. > i checked XF-4.3.0 at programs/Xserver/Xext/xf86vmode.c, function > ProcXF86VidModeAddModeLine(). it seems that clock field is not being > set on the structure returned by VidModeCreateMode(). > > that indeed explains the erratic behaviour because there must be > garbage on the allocated memory. > > may someone with more knowlegment of XFree86 confirm this bug? > > also, does it means that this function was never used before? I can't find any archives from the Xpert list, but last year I posted about the same analysis with some more notes. I did some hacking that let me add modelines (but not delete them), and basically just got this function working, however it was really hacked as I was much more interested in testing some theories more than finishing this (clearly incomplete) implementation. Nobody replied to my posts to Xpert asking how the code got in this shape in the first place: is this code just unfinished, a bad check-in, an unfinished port from 3.3 ? I don't quite understand. If you want me to try and dig up my code I can, but my advice is that we start over and finish the implementation of this extension from the 4.3 code. -- Billy Biggs [EMAIL PROTECTED] _______________________________________________ Devel mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/devel
