Is this a dual head card ? Are you using a digital or VGA output ?

With the problem X server running, can you run xdpyinfo -ext XFree86-VidModeExtension -display :0 (or whatever display you need). You may need to switch back to the text console to do this. Check that the "Current Video Mode Setting:" (the last 2 lines of output) match the modeline that the server log says it is displaying. This should confirm that the bug is in the xfree86/debian supplied mga driver. I have to say that although I've heard of people who use G550s without mga_hal, I haven't got any of my G550 cards to work without it; I'm using the digital output, which might be significant. -- Dr. Andrew C.
