I have 4.2 working fine with the Matrox 450. The upgrade did break things
at first. For some reason the new config file seemed to be the problem,
and everything worked when I restored the previous one (generated
incidentally by the MGAPowerdesk app).
I now have 1280x1024, though the log file does contain quite a few
messages of the form:
(II) MGA(0): Not using default mode "1280x960" (hsync out of range)
(II) MGA(0): Not using default mode "640x480" (bad mode
clock/interlace/doublescan)
(II) MGA(0): Not using default mode "640x512" (bad mode
clock/interlace/doublescan)
(II) MGA(0): Not using default mode "640x512" (bad mode
clock/interlace/doublescan)
(II) MGA(0): Not using default mode "1280x1024" (hsync out of range)
But it does work OK, using the drivers from the Matrox website.
