Another user-surley method is to use xrandr. You can experiment with it from
the command line, and then install it in a file in /etc/X11/xinit/xinitrc.d/.
I have two monitors, one of which doesn't report the EDID, and I wanted to use
them in a side by side. By runn ing xrandr from the command line, I was able
to determine the names of the two devices. I used the --addmode option to add
a new size option for the ancient monitor, and the --output option to use it.
I kept playing around with it until I got what I wanted. I was then able to
create an executable file, 99-xrandr, in the above directory containing:
#!/bin/bash
xrandr --addmode VGA-0 1280x1024
xrandr --output DVI-0 --mode 1680x1050
xrandr --output VGA-0 --mode 1280x1024 --right-of DVI-0
In KDE you can put the file in a user's start up file area ~/.kde/Autostart, I
am not familar with the location that gnome would want it.
In one system I had to use --newmode to create the 1280x1024 mode, but I don't
have that file avaliable on this computer (also it was on Fedora 8).
