Hi, xinit suffers from an upstream bug, which does not allow non-root X to be run without a display manager via startx or xinitrc. Several people have reported this on #guix. Currently if one runs startx as non-root, X reports: (EE) parse_vt_settings: Cannot open /dev/tty0 (Permission denied) This bug is further discussed in [1]. Redhat seems to have a patch [2], but it is unclear to me whether this has been applied upstream.
