Yes, you cannot run both nouveau and nvidia-drivers at the same time. But I do not want to run nvidia-drivers, it is only needed by cholmod and cuda respectively. And it was working for two years without any problems. (In reply to Juergen Rose from comment #2) > But I do not want to run nvidia-drivers, it is only needed by cholmod and > cuda respectively. And it was working for two years without any problems. You can't have two drivers (nouveau.ko and nvidia.ko) managing the same device, even if they serve different purposes as a display driver or general purpose processor. The upstream README in /usr/share/doc/nvidia-drivers/*/ explains how you can blacklist the nouveau driver in order to use the nvidia driver (at "INTERACTION WITH THE NOUVEAU DRIVER").

Thanks Jeroen for the hint. But I do not want to use nvidia-drivers as a display driver and disable nouveau. I want only to use cuda. Is there no more any way to use cuda, if nouveau is used as the display driver? Hi Jeroen, could it be helpfull to blacklist the nvidia.ko module? Does cuda need the kernel module or the libraries from nvidia-drivers? I removed again nvidia-drivers and addidtional cuda USE flag from /etc/make.conf. |
