Setting up some new Ubuntu/NVIDIA machines

Some new machines arrived in the lab including a Dell XPS 8930 Desktop with Dell UltraSharp U2518D monitor.

Here is how I configured the machine:

  • /etc/network/interfaces should be
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback

# The primary network interface
auto enp4s0
iface enp4s0 inet dhcp
  • /etc/hosts should be trout
  • The NFS entry in /etc/fstab
10.65.xx.yy:/volume1/homes /nfs/homes   nfs   vers=4.1,defaults    0       0

did not mount upon booting. I think this is because the order was wrong. This can be fixed by adding a file containing

mount -a

to /etc/network/if-up.d/fstab.

  • Monitor would never wake up after machine screen saver activated. This was because of the default open source Ubuntu Nouveau drivers. To fix, installing the NVIDIA drivers:

  • 5/2/2020 - after an update the external monitor stopped working. I followed and installed nvidia-driver-440 to fix.

For reference, the configuration of the machine is:

  • XPS 8930 Base
