KDM not working after systemd migration

mattbarszcz · 2012-10-15 04:01:25

I migrated my running desktop arch installation over to a systemd/initscripts configuration. sysvinit has been removed and systemd-sysvcompat has been installed as per the systemd article.

I have everything working as before except for kdm. Previously I started kdm vis inittab.

I have followed the instructions in the wiki (https://wiki.archlinux.org/index.php/Sy … er_systemd)

systemctl enable kdm.service

(this succeeds)

I do not have a default.target already set that would cause problems.

When I reboot the system, I get a text login and nothing on tty7. If I login as root and run a

systemctl --all

it shows that kdm.service has loaded (but I dont see KDM). If i run

systemctl stop kdm

systemctl start kdm

kdm will loads right up and works fine.

There isn't much more information in the documentation about this other than to enable the service it and it should work. Does anyone know why KDM doesn't load up automatically at boot (even though it starts automatically) or how I could further troubleshoot this?

Have you tried doing

ln -s /usr/lib/systemd/system/kdm.service /etc/systemd/system/display-manager.service

?

mattbarszcz · 2012-10-15 04:56:35

Before I ran that command I ran

ls -l /etc/systemd/system/display-manager.service

and got the output

lrwxrwxrwx 1 root root 35 Oct 14 02:20 /etc/systemd/system/display-manager.service -> /usr/lib/systemd/system/kdm.service

So it looks like the symlink was already created when I ran

systemctl enable

I tried to create it again anyway though and it just returned "ln: failed to create symbolic link ‘/etc/systemd/system/display-manager.service’: File exists"

Try adding default.target, like this:

ln -s /usr/lib/systemd/system/graphical.target /etc/systemd/system/default.target

Together with your existing display-manager.service it should work (it does for me at least).

Btw, when you review the output of systemctl and journalctl, can you see any errors (like system trying to load KDM but it fails for some reason)?

No luck with the default.target but here was an interesting section I found with journalctl:

It seems that systemd is trying to load KDM before the nvidia driver is loaded.

How can I rearrange the boot order to correct this? I thought systemd was supposed to figure out the order automatically.

bump?

sandsmark · 2012-10-19 01:03:47

# echo 'nvidia' >> /etc/modules-load.d/nvidia.conf

and off you should go.

(my KDM still fails to launch, though)

Thank you sandsmark! I guess forcing the module to load manually puts it ahead of loading KDM.

Thank you!!! I think I hate systemd more and more....
Exactly same problem and solution today...

Please don't necrobump old threads. I'm slightly curious as to why you think systemd is supposedly causing you this problem two years after the rest of us updated our systems (and the Arch documentation, which should always be search before posting), but I'm not sure there's much use in asking. And stow the anti-systemd talk. For most of us, that crap got old years ago.

Welcome to Arch. Had you not violated two of our forum rules and tossed in some flame bait in your first post I'd likely have been more amicable.
