Okay: The Bumblebee version in the USC didn't work for me, but the PPA does... Think I'll stick to that solution until Prime gets fixed.

I use a XPS 15z laptop form Dell with hybrid graphics (Intel HD 3000 (probably) and Nvidia Geforce GT 525M). Booting doesn't work out of the box, but by setting GRUB_CMDLINE_LINUX_DEFAULT="acpi_backlight=vendor dell_laptop.backlight=0 quiet splash" in /etc/default/grub it works. acpi=off when installing, removed that from the grub file when installed. I expected that the Prime feature introduced in kernel 3.12 (kernel 3.13.x here) would let me switch between the Intel and Nvidia cards as i like, instead of using Bumblebee, which doesn't work properly with everything. I've installed and tried both the nvidia-331 and nvidia-304 drivers. Exactly the same result from both. Attempting to switch to the Nvidia card in nvidia-settings (tried on almost all of the drivers available, including 331.38) resulted in an error message, in a new window, with no text. prime-switch in terminal gives this output: Segmentation fault (core dumped) Sudoing the process gives no output at all. No graphical performance boost either, still the Intel card... sudo prime-select nvidia gives this output: Error: alternatives are not set up properly Error: nvidia mode can't be enabled I've also tried Bumblebee (not PPA) a few times, but it's also unable to switch. I'm able to use the Intel card temporary, but I would really like to be able to use the full power of my computer...
