to configure it. This is known as "EDID" (no doubt someone here can tell
us what that acronym stands for). This is highly advantageous if your
monitor supports EDID (almost all monitors sold today do), as
configuration is totally automatic. The problem comes in if you have an
older monitor that doesn't do EDID, then you're screwed:

That's for my laptop, I have a similar problem with a desktop at work
where I have an older (~3 years) Dell monitor. My issues with the laptop
started when I moved from F11 to F12, but it has been several versions
of Fedora since I have been able to use full 1920x1080 resolution on
that old Dell at work. At home where I have a newer Dell monitor that
does do EDID, it works great on two different machines, one with the
Nvidia proprietary driver and one with the default nouveau setup.
So...why does the xserver and nouveau do the RightThing(tm) on the LiveCD (namely, stretches the background image across both monitors), but does the WrongThing(tm) (namely, duplicates the background image on each monitor) when it boots from the hard disk after the install?
Actually, I don't care why. :-)
What I'm after is a way to tell the xserver to do it just like the LiveCD does. I figure some boot (kernel?) parameter, or some command line option supplied to the xserver at boot time?
Thanks for the helpful info!
