How well do laptops with Nvidia Optimus work?
My external monitor works fine when connected to my laptop's dock using a VGA cable. However, with a DVI cable, I can't seem to pick it up. Googling led me to install the NVIDIA additional drivers. After installation, I rebooted as instructed, and then tried to run NVIDIA X-server settings. I got a message telling me:
"You do not appear to be using the NVIDIA X driver. Please edit your X configuration file (just run `nvidia-xconfig' as root), and restart the X server."
However, after running `sudo nvidia-xconfig' and then "sudo service lightdm restart", my GUI fails to reappear. After removing the xorg.conf file created by nvidia-xconfig, I can get my laptop display back with "sudo service lightdm start", but I can't seem to actually get the NVIDIA drivers to work with X.
