334.21 installer not detecting 780M

The 334.21 installer is raising an error saying it can’t detect any supported devices. I skip by that, and once I click accept on the EULA, it has the little bar on the bottom, but otherwise does nothing.

lspci output:

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GK104M [GeForce GTX 780M] (rev ff)

The “(rev ff)” at the end of that line indicates that some system component has cut the power to the GPU, which is why the driver can’t detect it. You’ll need to find and disable whatever is doing that.

Thanks, I ran it with primusrun and it saw the gpu. Sadly it errored out on install due to a distro script, so I’m downloading the CUDA 6 Ubuntu 13.04 RC and hoping it will work in 14.04.
