Requirements to run gdm

Desktop
1

Good evening,
I am helping a little to fix some of the T/2 Distribution packages. One of these would be gdm (I would like to use it myself). I got it to compile and build, but the problem is that when running the gdm command nmothing really happens. It’s like it is running, but I get no terminal output and no gui opens up.
Now the question: What are the runtime requirements needed to run gdm with noi problems? Is a systemd session required (T/2 Linux is still running with sysvinit, and I could not yet manage to run the os with systemd)?

Thanks in advance

Hi,

Yea gdm requires logind (from systemd) to function

3

I have systemd installed as a normal package, but does the session need to be booted with systemd or just it to be existent on the device as a package?

gdm uses logind extensively. it needs to be running.

I was able to make the system with systemd and I start gdm with startx. Now the problem is that I get just a black screen with the following output in the syslog:

Sep 8 19:46:25 localhost gdm: Gdm: Enabling debugging
Sep 8 19:46:25 localhost gdm: Gdm: Changing user:group to gdm:gdm
Sep 8 19:46:25 localhost gdm: GLib-GIO: Using cross-namespace EXTERNAL authentication (this will deadlock if server is GDBus < 2.73.3)
Sep 8 19:46:25 localhost gdm: Gdm: Lost GDM name on bus
Sep 8 19:46:25 localhost gdm: Gdm: Disconnected from D-Bus

I followed the guide on Troubleshooting . Is there a way to enable more debug output? Could maybe my xinitrc be not working with gnome (works with twm)?
Thanks in advance

Do you have gnome-session and gnome-shell installed? Does gnome-shell work for you?
