I am trying to install Cuda 7 on a Dell M3800 which has Optimus technology (Intel HD4600 + Nvidia Quadro K1100m). I am following the instructions to the letter on fresh installs of Ubuntu 14.04, Ubuntu 14.10, and OpenSUSE 13.2. I have tried .run and .deb / .rpm installs on all three.
In all package manager cases, Cuda 7 install works, but as soon as I reboot it bricks, before the login screen. I think it's at the ACPI daemon because if I boot into text mode it freezes there.
I can get Cuda 7 working if I use the .run installation (yes I blacklisted Nouveau as per the instructions), but in those cases I have to use a lightweight window manager (have tried i3 and LXDE) because hardware graphics acceleration becomes unavailable. Gnome 3 and Unity both fail, with Gnome on OpenSUSE crashing, and Unity freezing with no toolbar and no status bar (yes I tried all the usual ways of getting these back like reinitializing compiz etc - no luck).
So I can have Cuda 7 but then I lose graphics acceleration.
My Dell Precision M3800 is a 2014 machine which came with Windows pre-installed. Linux works perfectly on it if I don't install Cuda.
Does anybody know the specifics steps that I need to take to get Cuda 7 working with accelerated graphics on an Optimus-equipped notebook such as this one?
I am happy to disable Optimus and/or the Intel graphics if necessary as battery life is not very important to me. There is no such option in the bios of the machine.
