I forgot that the problem I had with the MGA driver in 4.1.0 is that my monitor won't sync up at all. I'm using the same mode line I've always used, so my assumption is that it's doing something funky with the timing that puts it out of range. So it's possible that the stock driver in 4.1.0 would work, if it worked with my monitor. > I really just got my G450/Athlon system built and haven't yet gotten to > tuned it up for FreeBSD/XFree86 (DRI, mga/agp modules, etc.; any URLs to > web pages or list posts appreciated).

The driver module linked into the XFree86 server. i.e. /usr/X11R6/lib/modules/drivers/mga_drv.o > To your problem, here are a few DGA tests: > > http://people.freebsd.org/~rhh/fxtv/dgatest.c > http://people.freebsd.org/~rhh/fxtv/dgafbtest.c > http://people.freebsd.org/~rhh/fxtv/tv-dgatest.c > > It would be interesting to see if these work for you, and what the first > one prints.

The second one doesn't work like it's supposed to. It's kinda hard to describe, so I put an X window dump here: http://people.FreeBSD.org/~ken/foo.xwd.gz The colors are off, but I think only the vertical line in the top left corner was yellow. The third one didn't work at all. It hung after printing out the pixel format information. The text output from the tests is attached.

Check that: 1) you see all 8 lines (2 in each corner: 1 horiz, 1 vert), 2) they are in the corners of your desktop, and 3) they are all pure yellow (no odd-color borders) Move everything away from the corners of your desktop, and then hit <ENTER>. Testing complete. Examine the screen, and then hit <ENTER>. ========== Any problems? ========== If you observe a DGA bug, first verify that the XFree86 FAQ does not discuss it: http://www.xfree86.org/FAQ/ If not, report it to the XFree86 Team. See the FAQ for details. (http://www.xfree86.org/cgi-bin/bugform.cgi) Be sure to report the -f number (fuzz) required to shift the lines into place. For debugging, it might also be helpful to include a URL to where you grabbed this program. -f NOTE: If all looks well with 'dgafbtest -f 1024', then the frame buffer is really 1024 bytes positive offset from where DGA says it is.
