If you have fb utils instaled /etc/fb.modes have a short list and man fb.modes have the format and other usefull info. gft comes with 4.0+ version of X and is based in the VESA Generalized Timing Formula. I do not known how to get gft program to generate interlaced modes, but the formula allows it. with gft 1024 768 60 -f you get the mode in fb.modes format Diego. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
