Have you tried the alternative method described here:
https://wiki.gentoo.org/wiki/Non_root_Xorg
Nope. It seems that the method I mentioned was somehow the first method
described in the Wiki.
I am wondering what are the differences between the two? Which one is
better?
The alternative method is definitly more secure for systems with
multiple user accounts. I believe the xorg ebuild should install the
binary with this sgid bit set, or provide a use flag for it.
In the meantime, since my system is mono-user and I don't want to bother
remembering to change the flag when xorg is reinstalled, I keep my user
in the input group.
