No sound, vpn problems with NM and nm-applet

[MoritzMaxeiner]

Hi, awesome project, but I ran into two problem that block me from using cdm:

I use Archlinux x86_64 (systemd) with the cdm-git package (compiles latest version from here) and I have an .xinitrc file to start i3 and Enlightenment17 that works perfectly with slim.
When I try to use cdm, however, after logging into the X session I do not have sound (a closer look reveals that the ACL permissions for the sound card do not get set when logging in with a user. A workaround for that would be to add the user to the audio group, but that's against the workings of systemd).
The more pressing problem is that I cannot start a VPN connection with nm-applet when starting the X session with cdm (no problems with slim), the journal states that NetworkManger cannot find the secrets for the VPN connection (which indicates to me that there a problem with the dbus sessions).

My configuration file /etc/cdmrc varies from the default one like this:

binlist=(
'/.xinitrc i3'
'/.xinitrc e17'
'/bin/bash --login'
)

namelist=('i3' 'e17' 'Console')

flaglist=(X X C)

consolekit=no

Apparently when you use startx/xinit from a tty the X session does not get your authentication unless you give it the vt argument for the exact same tty you're on (ttyx- > -- vtx):

Thanks for looking into this @Calrama. I'm having the same issue running CDM on Arch. Were you able to solve this? If so, can you explain how/where you passed the vt argument since xinit/startx isn't being called explicitly?

[MoritzMaxeiner]

Sadly no and as far as I can tell there's no easy solution for this, because when using systemd there's just no apparent way to carry over the authentication from a tty login at say ttyX (which cdm uses) over to a newly started X session on ttyY - unless X = Y, of course. All of this is based on information from 5 months ago, though, maybe something has changed since then and now there is some way in a new systemd version, but if so, I know nothing about it, as I made a tactical retreat back to slim.

After reviewing this and browsing my .cdmrc again I noticed the following promises to do exactly what you described:

# Where should the first X tty be spawned?
# special value `keep' causes to run X in current tty.
xtty='7'

After changing that line to xtty='keep', my authentication issues were solved. Turns out this was already known on the Arch forum.

Well, yeah, but that way you stay on the same tty instead of returning to the login prompt and the x session starting on tty(7+). What this does is allowing you to start the x session automatically on any (same) tty you login from. That's not what I wanted, but if it is for you, that's good.
