Start Xorg with systemd without desktop env

in flag
OlivierF

I try to start xorg from an systemd service without desktop environment. When I log in on tty1 as a normal user, and type "startx /bin/xterm", I have an xTerm open, it's perfect. But when I try to start automatically after boot Xorg via a systemd, It doesn't work.

Here is my systemd service file :

[Unit]
Description=Xorg server at display 0

[Service]
Type=simple
User=user1
Group=user1
SuccessExitStatus=0 1
ExecStart=/usr/bin/Xorg :0 -nolisten tcp -noreset "vt1"

[Install]
WantedBy=multi-user.target

My /etc/X11/Xwrapper.config file :

allowed_users=anybody
needs_root_rights=yes

I try to open a session after boot with agetty

/sbin/agetty --autologin user1 --noclear %I $TERM

The session open on boot, but Xorg doesn't start To try debug the issue, I connect myself by SSH to the machine and try to manually start Xorg with startx /bin/xterm -- :0 vt1 :

If user1 is NOT logged in on tty1 I have this error :

Fatal server error:
(EE) xf86OpenConsole: Cannot open virtual console 1 (Permission denied)
(EE)

And if user1 is logged in on tty1 :

Fatal server error:
(EE) xf86OpenConsole: Switching VT failed
(EE)

If I startx with root, I works...but I don't want to run Xorg as root...

How can I start Xorg by systemd service for a normal user ? Is it possible to start Xorg without any logged user on tty ?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
