Side note:

Why I say same resolution as screen is that the noise-texture.png that
is used is smaller than the screen and then tiled. If you wished, you
could create a funky smaller patterned image that will tile to make for
a more consistent background. Hmm... something like a (hint hint) darker
blue CentOS inspired look rather than the grey - god who chose drab
grey. :-(
