Hi, I want to use my Matrox G550 to directly provide an interlaced picture for my TV. I've build the small circuit found here: http://www.sput.nl/hardware/tv-x.html http://www.unix-ag.uni-kl.de/~pfeffer/tvout/ (German)
Two of my modelines look like this: (Complete list of all modes can be found in the attached XF86Config) modeline "pal_768x576" 14.75 768 784 864 944 576 582 588 625 -hsync -vsync interlace # H 15625 [Hz], V 50 [Hz] modeline "pal_720x576" 13.875 720 744 808 888 576 582 588 625 -hsync -vsync interlace # H 15625 [Hz], V 50 [Hz] The mga driver accepts these modelines without a problem. But when I start X and try to use one of these modes, the driver hangs with 100% CPU time. I've created debug logs of a working session (without using the "new" modes) and a broken session. Also I've checked that the bug occurs with XFree 4.2.0 of RH 8.0 and XFree 4.3.0 of RH 9. Any help is appreciated as I spent half of the night trying to get it working ;-) Cheers, Thomas
