I'm getting some distortion around the edge of the secondary display with my dualhead G400 Max. I've been exchanging messages with Ben, the Linux tech support guy at Matrox. He's informed me that this is a bug that was introduced sometime after XFree86 4.0.1h. Has anyone heard of this? I didn't see it on the bug tracker and will gladly submit it, but I want to make sure that this is, in fact, a bug with the driver. Adam |

Yep. I have this problem as well. Are you using the HALlib or fbdev for the second head? Using HALlib I have several problems which make the X server unuseable: Distortion around the edges of the second head (a "pixelated border", etc.) Frequent Sig. 11's when starting the server (I sometimes have to run "startx" five or six times before the server loads). Frequent Sig. 11's while in X Macrovision protection when using TV-output. Frequent crashes related to MTRR's wile starting the server (again, starting the server seval times will allow it to eventually load, this is without using matroxfb). The second head interferes with the use of the mgavideo drivers (marvel.sourceforge.net) for Marvels, RRG addons. ...And numerous other problems. I have solved this quite nicely by adding a Millenium II to my box, and using the second head of the G400 exclusively for video output for my RRG using the matroxfb stuff in the kernel. Also, I suspect that using the fbdev for the second head in conjunction with the matroxfb kernel stuff would yeild better (albeit unaccelerated) results. Unfortunately, I have yet to find any way to make this work. The BusID for the second head has to be present even when using the fbdev (?), but I don't know what this number should be. According to the kernel configuration notes, one can use fbdev with the matroxfb drivers for the second head, but does not into detail as to how this should be done. Speciflying Option "fbdev" "/dev/fb1" does not work without a valid BusID present, which doesn't make any sense to me, since the server should talk to the second framebuffer, and not the hardware directly. If anyone can give some pointers to use fbdev for the secondhead, I'd like to see your XF86Config section for the second device.
