I have been running the Mach64 xserver with my ATI graphics card and Samtron monitor. I replaced the ATI with a Matrox Millenium G450 16MB card and reconfigured XF86Config for the SVGA server recommended by xviddetect along with settings for my monitor sync. But every time i startx my monitor says 'sync out of range' and hangs. I tried different sync settings etc. but still no luck. Can anyone running this card under Xfree86 3.3.6 or 4 give me some clues to your Matrox card settings etc?
