Step 2 of section 5.4.1. 'Quick Start' of the handbook states to add a user who will run Xorg to the 'video' or 'wheel' group to enable 3D acceleration when available. The command given looks like it adds the user to both groups. Does it matter if a user is added to both groups?
 
When you are in wheel you can do su which can be a security issue.
I think normally it is enough to be in video to run xorg but i'm not certain.
You can try it out.

You mean this?
# pw groupmod video -m jru || pw groupmod wheel -m jru
Nope. That's a logical or. If the first command succeeds the second won't be executed. Only if the first one fails would the second command be executed.

No, it's fine if you add your user to both groups. But you may not want to add just anyone to the wheel group.
 
Interesting, thanks.

I added root as well. Probably a waste of time but the instruction did say to add everyone I want who can start GNOME so I did it.
 
I just performed a test on my PC.
A user not part of video group, nor part of wheel group, can start X & the xfce4 window manager

wheel is root's primary group. There is no root group. Primary groups don't need to be added, you cannot create an account without a primary group, so a user (any user) always has a primary group.
 
For that user not in any group , glxgears show 1700 fps. I can live with that :)
Mesa/X.org, llvmpipe like you said.
For the user in wheel & video group i have also, Mesa/X.org, llvmpipe.

No difference.
