On my desktop:
$ cat /etc/X11/xorg.conf
Section "Device"
Identifier "Card0"
Driver "nvidia"
BusID "PCI:2:0:0"
EndSection
(Without this, X doesn't start, complaining it can't find VESA)
echo $DISPLAY returns the same on both desktops.
Please note: This desktop was installed years ago and simply kept
up-to-date for the most part. But it does have the "xinerama" USE-flag set
globally.
I remember reading something about it, but not sure if this is the "new"
or "old" way of doing it. I need to check how my laptop handles it later
today/this weekend.
