Pascal, I tried your suggestions however: - my bios doesn't provide for switchable graphics - the packages you recommended were not found. I added the xorg edgers PPA plus I have the usual ubuntu repos enabled - so I wasn't able to get any further.
One thing I'm pretty sure about: Optimus is not enabled even when I try to install it. I ran /usr/bin/nvidia-settings from the command line and got the following message: ** (nvidia-settings:3951): WARNING **: PRIME: Failed to execute child process "/usr/bin/prime-supported" (No such file or directory) ** Message: PRIME: is it supported? no Segmentation fault (core dumped) I've seen this reported as a bug on one of the linux launchpad message threads. My guess this is more of the ongoing saga of Linux and graphics drivers, it's clear not a DT specific issue. The graphics drivers have always been the biggest downer for me about using Linux - not that I'm blaming the devs, they've just been dealt a tough hand to deal with given the reluctance of the GPU manufacturers to colaborate.
