Bug Description

When I try to try to autodetect the screen Sony SDM-M51 with VGA card Matrox
MGA200, it configures it at 800x600 although it would be possible to run it at
1024x768.

It uses DefaultDepth 24
HorizSync 30-60
VertRefresh 50-75

The card is recognized correctly with 8mb Ram and driver mga

Hello,

Have you had a chance to test your hardware with dapper (a live CD perhaps)? If so are you still seeing this problem? Thanks.

Lucas, according to the Xorg.6.log file you attached to this bug, the mga driver can detect the 1024x768 resolution correctly - this seems to be a DDC detection problem, not a driver issue.

If possible, please attach the output of "sudo ddcprobe", and "sudo xresprobe mga".

Thank you in advance!

(also, I've changed the bug to 'xresprobe' instead of 'xorg', since it appears to be a DDC problem)
