axel's dev corner

Well, it was time to discard my old Xinerama xorg.conf in Kubuntu Jaunty. From a few friendly hints I finally managed to establish a simple procedure. I installed the manufacturer driver a while ago.

1. Start X with an empty configuration or sudo nvidia-xconfig and only one monitor
2. Connect the second monitor
3. Start nvidia-settings and add the second monitor. Save the configuration.
4. If the Resolution is not sufficent, add Monitor sections for all Monitors and set the metamodes to auto

So, my xorg.conf now looks like this:

# twinview, both monitors set via section and nvidia-auto-select
