Hi

I use ubuntu 6.10 on my intel mac mini for a mythfrontend connected to a 
dell 2005FPW.

There are pre-built in resolutions in the video bios you may need to 
override.  You can use 915resolution util to list/modify them.

Intel 800/900 Series VBIOS Hack : version 0.5.2

Chipset: 945GM
BIOS: TYPE 1
Mode Table Offset: $C0000 + $269
Mode Table Entries: 36

Mode 30 : 640x480, 8 bits/pixel
Mode 32 : 800x600, 8 bits/pixel
Mode 34 : 1024x768, 8 bits/pixel
Mode 38 : 1280x1024, 8 bits/pixel
Mode 3a : 1600x1200, 8 bits/pixel
Mode 3c : 1680x1050, 8 bits/pixel
Mode 41 : 640x480, 16 bits/pixel
Mode 43 : 800x600, 16 bits/pixel
Mode 45 : 1024x768, 16 bits/pixel
Mode 49 : 1280x1024, 16 bits/pixel
Mode 4b : 1600x1200, 16 bits/pixel
Mode 4d : 1680x1050, 16 bits/pixel
Mode 50 : 640x480, 32 bits/pixel
Mode 52 : 800x600, 32 bits/pixel
Mode 54 : 1024x768, 32 bits/pixel
Mode 58 : 1280x1024, 32 bits/pixel
Mode 5a : 1600x1200, 32 bits/pixel
Mode 5c : 1680x1050, 32 bits/pixel

In my case I want 1680x1050 for my monitor and have '915resolution 5c 1680 
1050' in /etc/rc.local.  The bios modes will reset if you reboot the mini.

Attaching my xorg.conf and a patch for XV on mythtv.

The XV patch fixes blue screen when you try to watch HD content.  There 
are 2 XV ports, the first one claims to handle 1920x1080 but it cant.  The 
patch makes it pick the 2nd port which can do 2048x2048 images.
