 Posted: Wed Jan 19, 2011 1:25 pm Post subject: autologin user on startup without dm (consolekit "obsta |
 |
|
hi all,
based on my consolekit odyssey (https://forums.gentoo.org/viewtopic-t-858504.html) i started a new thread.
i'm using my system as a dedicated htpc. for convenience i have to autologin my user and do not use a keyboard or mouse.
requirements:
- no dm usage because i try to keep my system as slim as possible.
- global xsession to prevent the user to accidentially delete the contents in ~/
- therefore no ~/.xinitrc or ~/.bash_profile solution
- respawn the session in case xbmc or x crashes (i used to use a while loop for that kind of jobs)
already tried:
- autologin via sudo or su does not respect consolkit and results in unactive sessions
- does not make any difference whether or not one takes this approach over /etc/inittab or /etc/init.d/local
does anybody know or recommend a way to accomplish this task while taking consolekit into consideration to maintain the privileges to mount, reboot, shutdown, etc. the system?
thanks for you help && regards,
hal2050 |

Turns out nodm didn't play well with consolekit either.
But I'm now using slim with auto-login where consolekit works great so I can shutdown, reboot, etc. from within xbmc. |

hehe. indeed!
i installed nodm last night and after the first reboot my system hung pretty early in start up procedure where the system deps are getting cached, (chaching system dependencies) producing errors in an infinite loop about net.eth0 and sth else i can't remember right now. chrooting, uninstalling nodm and running
| Code: | | /lib/rc/bin/rc-depend -u |
fixed it.
now i'm heading over to qingy. 
edit:
right now qingy basically works. but again i don't get an active session with consolekit. below you can find my setup:
cat /etc/env.d/90xsession
| Code: |
XSESSION="XBMCsession" |
cat /etc/X11/Sessions/XBMCsession
| Code: |
#!/bin/bash
while true; do
ck-launch-session /usr/lib/xbmc/xbmc.bin --standalone --nolirc
sleep 1
done |
cat /etc/pam.d/system-login
| Code: |
auth required pam_shells.so
auth required pam_nologin.so

account required pam_nologin.so
account include system-auth
password include system-auth

remote-host-name = ''
is-local = FALSE
on-since = '2011-01-20T12:39:16.627858Z'
login-session-id = '' |
as you can see i don't get a session id and active = false.
anything special i should look at in addition?
qingy seems to support consolekit/pam officially since 12.2010 (referring to their news section). |

any qingy users around?
what should be the contents of "/etc/pam.d/qingy"?
cat /etc/pam.d/qingy
| Code: | # File autogenerated by pamd_mimic in pam eclass
auth include system-local-login
account include system-local-login
password include system-local-login
session include system-local-login |
or in addition to the above
| Code: | session optional pam_loginuid.so
session optional pam_ck_connector.so debug |
?
i read the latter in this report: https://bugs.gentoo.org/345135 |

update:
i found out that i get an active session when i login manually with qingy. as soon as qingy takes over to autologin an user i end up with an unactive session, again.
this tastes like a bug. therefore i filed a new report upstream. |

thanks for the url, ssuominen. 
but it's funny because i stumbled upon this thread earlier the day and already tried that approach. the downside is mingetty drops the user to a shell. just like you would login manually on the login prompt. one could also put "/bin/login -f $USER" into "/etc/inittab" resulting in the same effect like mingetty produces.
i guess i have to give up for now and wait and hope until qingy or su/sudo will get an update to work together nicely with ck. |

Here's my solution, just stick the attached script into /etc/local.d/X.start and make it executable. It starts X utomatically and sets up an activated consolekit session as well. You need to have python-dbus installed. Change the USER variable to the username you want auto-logged in.
| Code: |
#!/usr/bin/python2
# vim:fileencoding=utf-8
from __future__ import (unicode_literals, division, absolute_import,
print_function)

# Wait at most two seconds for DBUS and ConsoleKit to be available

At the risk of being excommunicated for posting heresies on this forum, the following has been working flawlessly for me for many years. Edit /etc/inittab and change the first TERMINALS entry as shown:
| Code: |
# TERMINALS
#c1:12345:respawn:/sbin/agetty 38400 tty1 linux
c1:12345:respawn:/bin/login -f root 38400 tty1 linux
c2:2345:respawn:/sbin/agetty 38400 tty2 linux
c3:2345:respawn:/sbin/agetty 38400 tty3 linux
:
|
X can be started by adding 'startx' at the end of ~/.bash_profile, but you may want to disable this for SSH logins:
| Code: |
echo TTY = $(tty)
if [ $(tty) = /dev/console ]
then
startx
else
echo No X via TTY
fi
