I've got two HP monitors, an LP2065
and and L1940T
, both of which are connected to a single NVidia card.
Both can also be rotated, but one turns only left, while the other turns only right.
So if I use one virtual screen and rotate it, one will be displaying correctly, the other upside down.
I found good documentation on TwinView on gentoo-wiki and on xrandr at ThinkWiki, but decided against it, and instead did this:
sudo rm -rf /etc/X11/xorg.conf
sudo apt-get install nvidia-glx nvidia-kernel-2.6-amd64 nvidia-kernel-2.6.26-2-amd64 nvidia-kernel-common nvidia-settings nvidia-xconfig
sudo nvidia-xconfig
startx
sudo nvidia-settings
... and enable both screens, putting one left of the other
In /etc/X11/xorg.conf
, put a line
Option "Rotate" "left"
in the monitor
section of one monitor, and
Option "Rotate" "right"
in the monitor
section of the other.
Restart the X server
