You're running one linux shell within another using VirtualBox.
...Yeah, that looks like a very intelligent use of your computer.
well i don't really feel like installing probably 250 packages, then spending time uninstalling things and reverting back to what i'm using primarily.
also, it's not "another shell", it's arch. i like being able to snapshot in virtualbox because it makes uninstalling a bit easier, and if something breaks, welp, just revert back.
so it is very intelligent actually. it's a good way to experiment with things without breaking the host. i actually broke this with lightdm once unintentionally.
i mean if you want to spend time installing xfce and some other applications and then uninstalling said things + reverting old settings with the chance of breaking something important, by all means go ahead ;)
kinda shocked you didn't comment on the pipes wallpaper in the background either. that takes up a little cpu.
then again it is running under "nice 19" so anything else could take priority over it easily.
