Garbage collection won’t make a difference here.

According to the definition of the “xfce” and “xfce4-panel” packages,
plugins are searched for on directories listed in the environment
variable “X_XFCE4_LIB_DIRS”.  Try setting that to the directory
containing “xfce4-cpugraph-plugin” before Xfce is started.

Indeed, just run it when you need more disk space.  On some machines I
have “guix gc -F100G” run periodically, which ensures that 100G of disk
is available.

It works! Thanks.

Technically you don't need to always call `guix gc`.

Also note that generations are generally lightweight, especially for
simple operations like installing a single package.

There is no other way.  Guix always generates a new generation of your
profile.
