[ale] systemd or not

XFCE doesn't use anything from the OpenGL acceleration realm. So it can fly
compared to the opengl emulation software that gnome uses if the hardware
doesn't support real OpenGL hardware acceleration.

And, yes, OpenGL_was_ a Silicon Graphics thing that was sold to Microsoft.

Every time you stop a school, you will have to build a jail. What you gain
at one end you lose at the other. It's like feeding a dog on his own tail.
It won't fatten the dog.
- Speech 11/23/1900 Mark Twain
