[sf-lug] modifying the screen resolution under Ubuntu

[Christian Einfeldt]

hi,

I am trying to change the default screen resolution on one of the giveaway
boxes at the school.  The default is currently set for 1680 x 1050.  I have
tried going to System > Screen resolution, but when i click on change screen
resolution, and choose 1024 x 768, I get the option to accept the screen
resolution, but in fact, the screen resolution does not change.  So I tried
going into /etc/X11/xorg.conf , which has worked before, but this time,
there was no entry for the screen resolution.  I am copying my xorg.conf
file to this email, in the hopes that someone will be able to tell me what I
am doing wrong, because this screen resolution is just way too small.

Thanks in advance.
