Hello. I want to use Tesla K20m for CUDA computations and Geforce 210 for gui rendering in my PC.
I installed Ubuntu 20.04 and faced with troubles:
system detects only Tesla K20m in Drivers application but monitor is connected to Geforce 210 and it renders gui in resolution 640x480;
sudo ubuntu-drivers devices also shows only Tesla K20m card;
lspci shows both devices;
nvidia-smi shows only Tesla K20m (if nvidia drivers are installed).
I tried to edit xorg.conf to render gui using Geforce 210 but nothing changed.
The most recent nvidia driver for Geforce 210 is 340 and for Tesla K20m is 470. I tried to specify in xorg.conf nouveau driver for Geforce 210 but nothing changed.
Please tell me can I force my configuration to work as I want?
Please don’t use options nouveau modeset=0, remove that.
For testing that this setup will work at all, you should disable Xserver autostart sudo systemctl disable display-manager
after reboot, log in on console and check that the nvidia driver is bound only to the tesla and the noveau driver didn’t load sudo lspci -k -d 10de:*
Then load the nouveau driver sudo modprobe nouveau
and check that nouveau now is bound to the gf210 sudo lspci -k -d 10de:*
if all is well, try starting the Xserver sudo systemctl start gdm
If this works, create a systemd unit that loads the nouveau driver before display-manager starts and re-enable the display-manager sudo dpkg --reconfigure gdm
