[SOLVED] gdm freezes when started as service (systemd)

Hey,

I've run into a weird issue here: when I reboot my laptop, it gets stuck after the "file system clean" messages and GDM won't come up.

After some time, it shows a "oops, something has gone wrong"-message and I can log in, but my settings are gone (mouse moves slowly, battery applet shows no battery, etc.).
After a few minutes, gnome-shell will crash.

sudo systemctl status gdm.service:

gdm.service - GNOME Display Manager
   Loaded: loaded (/usr/lib/systemd/system/gdm.service; enabled)

last lines (those with "gdm[404]" get repeated when it crashes".

However (!) when I disable gdm.service and put "exec gnome-session" into my xinitrc and call "startx" it works just fine.

Any ideas?

I have nearly the same problem. But my gnome crashes instantly after "startx". Came with an update i think.

Re: [SOLVED] gdm freezes when started as service (systemd)

I just tried "systemctl start gdm.service" from tty twice. First time was good, the second time I had the same old error again.
I also tried running gdm as root with the same result.

Running gnome-session works fine, so it's either a gdm or systemd thing...

edit: just found this in the log

Re: [SOLVED] gdm freezes when started as service (systemd)

Looks like I fixed it by removing old stuff, namely:
- dkms-apci_call-git (AUR)
- hal (AUR)
- hal-info
- open-vm-tools-dkms

Not sure, which of those packages caused the bug though...
