xorg-server: default Xwrapper.config forces Xorg to always run as root

[r00tman]

Is there a reason we keep needs_root_rights = yes in /etc/X11/Xwrapper.config, when we can change it to needs_root_right = auto? The latter would allow Xorg.wrap to drop root privileges if it detects that KMS is supported.

System

• xuname:
  Void 5.1.21_1 x86_64-musl GenuineIntel uptodate rF
• package:
  xorg-server-1.20.5_1

Expected behavior

Xorg.wrap drops root privileges if all cards support KMS

Actual behavior

Xorg always runs as root.

Steps to reproduce the behavior

Use default Xwrapper.config

In my experience, change needs_root_rights to auto requires adding user into input group to use the keyboard, mouse. We need to figure out which user should be added, and how.

The only "safe" way this can work is by building xorg with elogind support by default, which I don't think will ever happen.

Can add a docs entry about it, maybe.
