I seem to recall there was a popular set of timings that represent the standard VESA compliant settings? But I lost track of it.
However, if an ancient X works for you, you should be able to ask xvidtune what modelines it *really* ends up using. Run an xterm or other x-based console, and run xvidtune from that. don't even bother running it as a background job. Say OK to the nasty dire warnings, esp. since you won't be changing anything, and use the SHOW button. Your xterm will show the modeline it really uses. Use mouse cut-n-paste to paste this into a text editor, any one will do, just so that you have it saved aside. use NEXT, SHOW, capture the modeline. repeat until you have all your supported modes. The most common "problem" is that LCDs often support lower hsync than 30, the default low point. The second most common is that many LCDs demand a particular dotclock (the first field in a modeline after the "name") but the typical X server "best guess" takes the highest vsync and hsync, doesn't care about the dotclock. Once you find usable modelines you can also use them for SVGAlib. * Heather Stern * star@ many places... > On Sun, 21 Jan 2001, Michael Bauer wrote: > > > > > > it's the 11.3 active matrix model. i've found other people's configs > > > online, but none of them seem to be helpful at all. the best i've gotten > > > is 640x480 with messed up colors and flickering that makes it impossible > > > to read, much less look at. > > > > It would be useful, if you give us informations of the graphic-card.
