This still actual, but process name console-kit-daemon. KDM\XDM also affected.
This bug appears in Debian and ArchLinux both, may be in other distros.
Archlinux, consolekit 0.4.1
when console-kit-daemon launches, it grabs currently active vt.
ck-launch-session does not work on vt grabbed by console-kit-daemon.
This bug breaks qingy experience: can not launch session twice on same tty, it hangs.
If using other DM's, tty7 gets blocked after first use.
add this line to rc.local to force console-kit-daemon launch on distant tty:
openvt -c 63 -f -- console-kit-daemon --no-daemon &
may not work with some graphical login managers, as they may launch it sooner.
Anything running console-kit-daemon is affected.
Another workaround is to run console-kit-daemon w/o "--no-daemon" before starting any X server.
Otherwise, tty7 gets blocked every time.
when running it without "--no-daemon", it grabs currently foreground vt, no matter what vt it was launched from. With "--no-daemon" you can pin it to desired vt in background.
So it can stay on tty1 this way. It does not cause any problems there. I added it to rc.local
I have slackware 13.1 64bit and kde 4.4.3 and i have the same problem.
However i did what you suggested, with the rc.local, and it's ok now.
I am worried about no progress. Surely, there is a workaround I've found but a workaround shouldn't be considered as a fix.
I vote for a fix. Google "tty7 tty8" and you'll see everyone is complaining about the bug... It doesn't really matter (to me), but that's clearly no good behavior.
