Feature: twdm, Add dbus support?

[mikedebian]

If I don't use getty at the TTY, but twdm and I login to startx, I get dbus errors. Steam complains about dbus errors, and systemctl is unable to load user entries.

If I start X from getty, no problems arise. I don't know what causes this or if you are aware of this. I will give any info that is needed.

journalctl

Steam spams with

Failed to connect to bus: No such file or directory

You are trying to use Steam in an unsupported way. This really isnt a twin issue.

[mikedebian]

I have launched X from the Twin Display Manager into an Openbox graphical session. I do not understand your comment. It is about X and applications not being able to connect to dbus if started from twin. Steam was just one of the examples. See the other examples. There are hundreds of use cases where applications are not able to connect to dbus if X is started from TWDM.

I am definitely not an expert of dbus, and I do not know which process is in charge of starting dbus at login. Any pointer for dbus documentation related to dbus initialization at login? Thanks :)

[mikedebian]

systemd is in charge of dbus on opensuse.

systemctl status dbus.service

It may seem that XDG_RUNTIME_DIR (among others, but I read this is important for dbus) is not set when running twdm.

agetty > X

 env | grep XDG

    XDG_CONFIG_DIRS=/etc/xdg
    XDG_DATA_DIRS=/usr/share
    XDG_RUNTIME_DIR=/run/user/1000
    XDG_SEAT=seat0
    XDG_SESSION_ID=1
    XDG_VTNR=2

Under TWDM > X

 env | grep XDG
 
    XDG_CONFIG_DIRS=/etc/xdg
    XDG_DATA_DIRS=/usr/share

Say also for example if I log in to TWDM and it starts a TWIN-TERMINAL. It goes to my ~ directory automatically (/home/username).

It does not read from .bashrc, and I don't know if it's supposed to do that or not, however if I am in my directory and type "source .bashrc", it will complain that the file is not found, even though it is there, so I need to type the entire path, like so : "source /home/username/.bashrc". It then reads it and loads it. I guess this is relevant to XDG directories in TWDM?

[cosmos72]

Thanks for reporting these issues. Yes, TWDM does not setup perfectly the login environment. I will work on that.

[mikedebian]

Thank you very much :) I'm looking forward for the results!

Whatever you do, though, please try to make these dependencies optional for users as a whole of linux, even more so though, especially, BSD users.

This project looks interesting, btw, it would be even more interesting if there was an ultra secure, lightweight, few dependencies required, minimalistic alternative to wayland and x11 for both BSD and gnu/linux distros as a whole. I don't know if you consider the gnu/linux ideal needed to be said or not, but I prefer to not offend people if I can help it...
