If your HP G200e is working, then so should Chris' be able to as well. The G200e is a special evolution of the original G200/G400/G450/G550/G650 series that last I knew was no longer supported upstream since KMS matured. AFAIK, the G200e was supposedly the only chip supported by MGA X driver patches intended to keep X viable on HP servers without anyone willing to provide kernel support for KMS on Matrox. I do have the MGA driver xserver-xorg-video-mga dysfunctional on (an AGP) G550 in i686 Bullseye by disabling KMS via nomodeset on, and adding iomem=relaxed to, the kernel command line, without installing firmware-misc-nonfree. The dysfunction is the screen blanks momentarily at random times, but is otherwise normal as long as xrandr is not needed to configure the screen. Installing firmware-misc-nonfree doesn't help. -- Evolution as taught in public schools is, like religion, based on faith, not based on science. Team OS/2 ** Reg. Linux User #211409 ** a11y rocks!
