[Nottingham] New Monitor

[Jim Moore]

start with:

xrandr --addmode XSVGA 1366x768

then:

xrandr --output XSVGA --mode 1366×768 --rate 60

Note these are nonpersistent commands (ie they'll only last through
the current session). You might want to add them to xorg.conf (read
the xorg.conf file on how to add xrandr lines to the configuration),
or you can use ~/.xprofile (just append those two xrandr lines to the
file; create an empty xprofile if one doesn't already exist, xorg will
use it if it exists in your home folder).

As mentioned (kudos to Matthew), ATI and NVidia both have GUI
configurations in which setting up custom screens is elementary. I
know from experience (with SuSE Pro 9.3) that the NVidia one does
require you to set the pitch or it'll do weird things with weird
screens (apparently the hardware manufacturers never thought to add
16:9 aspect screens to the default list) /before/ you can add the new
screen resolution.
