[SOLVED] no login at tty1 - cannot open as standard input: Input/out

Hi,

after booting today i could not login in at tty1. The last 3 systemd messages are still visible. The other ttys work fine and i can login on tty2.
Here is the relevant part of the journal

Feb 25 12:38:22 systemd[1]: Starting Getty on tty1...
Feb 25 12:38:22 systemd[1]: Started Login Service.

Have you tried restarting getty@tty1? Does that give the same I/O error?

Restarting getty@tty1 works, there are no errors, then autologin happens and the prompt is shown.

Re: [SOLVED] no login at tty1 - cannot open as standard input: Input/out

I found out what causes this problem. I am using autologin as it is explained in the wiki, with a drop in file.

[Service]
ExecStart=
ExecStart=-/usr/bin/agetty --autologin username --noclear %I 38400 linux
Type=oneshot
Restart=no

After removing this file the login prompt is shown again, but autologin is disabled.

Maybe this can be useful https://wiki.archlinux.org/index.php/Sy … _gettys.3F

I love archlinux: the last STABLE kernel release + the last STABLE DE release + the last STABLE apps releases. The upstream developers decide what is STABLE.

Re: [SOLVED] no login at tty1 - cannot open as standard input: Input/out

I removed the last two options from the dropin file, and enabled the dropin file again.

[Service]
ExecStart=
ExecStart=-/usr/bin/agetty --autologin username --noclear %I 38400 linux

Now autologin is working again. But i do not want the agetty service to restart, because this is a security hole together with autologin. This is what "Restart=no" was intended to do.

Re: [SOLVED] no login at tty1 - cannot open as standard input: Input/out

Solved. I only had to remove the "Type=oneshot" line, so the working config for autologin without restart is:

[Service]
ExecStart=
ExecStart=-/usr/bin/agetty --autologin username --noclear %I 38400 linux
Restart=no
