I have the following two video cards installed in my Arch Linux system:
$ lspci | grep -i vga 01:00.0 VGA compatible controller: NVIDIA Corporation G84 [Quadro FX 1700] (rev a1) 02:00.0 VGA compatible controller: NVIDIA Corporation GF100 [Tesla C2050 / C2070] (rev a3)
Currently, I am using the
nvidia-utils packages for both the
display and CUDA. However, I get better display stability when I am using
Nouveau. If I install the package
xf86-video-nouveau and comment out the
/usr/lib/modprobe.d/nvidia.conf, then Nouveau appears to take
over both cards. In this state
nvidia-smi returns the following:
$ nvidia-smi NVIDIA: could not open the device file /dev/nvidiactl (No such file or directory). NVIDIA-SMI has failed because it couldn't communicate with NVIDIA driver. Make sure that latest NVIDIA driver is installed and running.
Is it possible to "attach" Nouveau only to the Quadro and let the Nvidia driver pick up the Tesla?
