I spent some more time and was able to get things working on my machine, so I though I'd share how. Note this is definitely a hack but it works and perhaps Alberto or Tim could give directions on a temporary fix that is less hacky while we wait for the official fix to be posted somewhere.
1. In /etc/gdm/Init/Defaut, add the line /sbin/prime-offload right before the exit 0. Or better, write your own script to call "Default" and then run prime-offload. 2. Unlike older version of nvidia-prime, newer versions don't appear to generate an xorg.conf file. But with my hack fix, it still needed when in "nvidia" mode. So after I do a "prime-select nvidia" I create an xorg.conf file in /etc/X11/ with the following contents: ######################################## Section "ServerLayout" Identifier "layout" Screen 0 "nvidia" Inactive "intel" EndSection Section "Device" Identifier "nvidia" Driver "nvidia" BusID "PCI:1:0:0" EndSection Section "Screen" Identifier "nvidia" Device "nvidia" # Uncomment this line if your computer has no display devices connected to # the NVIDIA GPU. Leave it commented if you have display devices # connected to the NVIDIA GPU that you would like to use. Option "UseDisplayDevice" "none" EndSection Section "Device" Identifier "intel" Driver "modesetting" EndSection Section "Screen" Identifier "intel" Device "intel" EndSection ########################################## Then reboot for nvidia mode. Note that when you want to enable intel mode, you'll need to remove this file and reboot. Like I said, a total hack but it enables nvidia mode for me which is all I needed for now. One other issue I saw was that the /etc/init/nvidia-prime.conf has some specific use of lightdm. Whatever it's doing there, I guess it needs to do for gdm as well. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-prime in Ubuntu. https://bugs.launchpad.net/bugs/1262068 Title: nvidia-prime should support gdm also Status in Ubuntu GNOME: Triaged Status in “gdm” package in Ubuntu: Confirmed Status in “nvidia-prime” package in Ubuntu: Fix Released Status in “ubuntu-drivers-common” package in Ubuntu: Confirmed Status in “nvidia-prime” source package in Precise: Fix Released Bug description: On Ubuntu GNOME we ship gdm by default, however nvidia-prime depends on lightdm. This means that 1. Anyone installing nvidia binary drivers will pull in nvidia-prime and subsequently lightdm. As a consequence of this they are also going to get the potentially confusing dconf pop-up asking them to choose a DM. 2. nvidia-prime probably won't work when using gdm I haven't looked to closely at how deeply integrated this is with lightdm, however we particularly don't want #1 happening, and it would be nice if #2 worked.
