Adjust Mythbuntu screen resolution
This one bugged me a lot. I have a full hd tv and I was staring at an awesome 640x480 distro of Ubuntu. Let's get on with it shall we?
Log in as root:
su - root
Stop gdm:
/etc/init.d/gdm stop
Create xorg.conf file:
xorg -configure
(this generates /root/xorg.conf.new, move to /etc/X11/xorg.conf)
Generate "modeline" to insert into /etc/X11/xorg.conf under monitor section.
cvt 1920 1080 60
arguments: width height refresh
example output:
Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
Restart gdm:
/etc/init.d/gdm start
The new screen resolution should now be under display settings. Follow the steps again to add more screen resolutions.

root password is disabled in ubuntu by default.(security reasons) use “sudo su” instead of “su” if you want to became root..
You can then enter your mythbuntu admin password
