Ubuntu 11.10 Nvidia Thinkpad W520

There’s a lot of stuff on the web about how to setup your nvidia card with ubuntu. After a lot of work, I am able to switch between single and dual monitor setup with an nVidia Quadro 1000M video card on my Lenovo Thinkpad w520 running Ubuntu 11.10. The following is an instruction list that worked for me.

        cp /etc/X11/xorg.conf /etc/X11/xorg.conf.original
        sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
        apt-get --purge remove ALL_THINGS_NVIDIA
        apt-get install --reinstall nvidia-173 nvidia-173-updates nvidia-settings
        apt-get install --reinstall  nvidia-current nvidia-current-updates # necessary?
        BusId "PCI:1:0:0"
        Option         "RegistryDwords" "EnableBrightnessControl=1"
        Option         "NoLogo" "True"
* Where the BusId bit is determined by the output of:
        $ lspci | grep -i nvidia | grep -i VGA | cut -d " " -f 1
        blacklist vga16fb
        blacklist nouveau
        blacklist rivafb
        blacklist nvidiafb
        blacklist rivatv


        $ apt-add-repository 'deb http://ppa.launchpad.net/disper-dev/ppa/ubuntu YOUR_UBUNTU_VERSION_HERE main'
        $ apt-get install disper
        $ cp /etc/X11/xorg.conf.original /etc/X11/xorg.conf
        ## Don't forget to unblacklist the stuff in blacklist.conf! ##
        $ sudo reboot
        ## Did you change the BIOS?
