And only does this in 1280x1024, not 1024x768. Yep.

Both look ok. I can move the windo around the window and it tracks just fine. > 2) Please add this line after the line you patched: > > printf( "geometry = X %4d, Y %4d, Bpp %d\n", g.x, g.y, Bpp ); > > and try "-geometry +0+700". Does it print something very close to "X 1, > Y 780, Bpp 4" (the location of the video window relative to the root > window)? petry@netwolf[94]$ ./fxtv -geometry +0+700 geometry = X 5, Y 781, Bpp 4 > > For calibration, does -geometry +0+0 give you an Fxtv window in the > upper-left corner of the desktop and print out something very close to > "X 1, Y 80, Bpp 4"? petry@netwolf[95]$ ./fxtv -geometry +0+0 geometry = X 5, Y 81, Bpp 4 > 3) See if this makes any difference: > > --- xutil.c.ORIG Mon Sep 29 18:21:43 1997 > +++ xutil.c Mon Sep 29 18:21:51 1997 > @@ -735 +735 @@ > - XUTILGetVisualBpp( display, vi, &Bpp, NULL ); > + XUTILGetVisualBpp( display, vi, NULL, &Bpp ); No difference. > DGA pitch is right, or you wouldn't see a solid rectangular video block. > Could be that XTranslateCoordinates doesn't work correctly on Milleniums > for 1280x1024x24bpp. > > BTW, please try this on XFree 3.3.1. XFree86 Version 3.3.1 / X Window System (protocol Version 11, revision 0, vendor release 6300) Release Date: August 4 1997 . .

You've got a Millenium, right? Do you see this too (or can > you run at 1280x1024x24bpp)? It feels like there may be a 1024 byte offset from the beginning of the linear frame buffer. When I first go the board and ran in 1600x1200 mode the video was shifted both horizontally and vertically (I guess pitch was wrong). I'll try it agai and let you know if it gives anything interesting.
