GDM starts in fallback after boot

Bhran · 2012-05-01 20:43:33

It's been happening since 3.2, whenever I boot the computer, gdm shows without the "gnome-shell look", it looks like the old gdm from 3.0.
When I login, gnome-shell starts fine, no fallback mode. The complete Gnome 3 experience, and then when I logout, gdm also sports the gnome-shell semi transparent black curved border style that is how it's supposed to look.

This happens only the first time gdm is called after boot.

Any help?

Hmm, same is happening here. Also, sometimes a different GTK theme is loaded, it looks like an older one.

Ok, it's a timeout issue:

gnome-session[772]: DEBUG(+): fill: *** Looking if /usr/share/gnome-session/sessions/gdm-shell.session is a valid session file
gnome-session[772]: DEBUG(+): fill: *** Launching helper 'bash -c 'gnome-shell --help | grep -q gdm-mode && /usr/lib/gnome-session/gnome-session-check-accelerated'' to know if session is runnable

Did you find any solution?

same here.

I've even tried to set the IsRunnableHelper to true in gdm-shell.session but is still hanging.
Is this a bug? I found some posts in a french forum but they still can't solve it.

Hey Bhran,
yes this is indeed the same issue. It occured to me twice, once on my laptop and once on my netbook, both using GDM3 and Cinnamon. The odd thing is that i could repair it on my netbook, reinstalling the following packages in an order i don't remember: gnome-menus2, muffin-wm (or muffin-git when Cinnamon 1.4 wasn't released and i had to use cinnamon-git).
This actually doesn't work on my laptop. I already tried reinstalling GDM and also gnome3, but this doesn't help either.

Sadly I can't see how that's related with our problem as grsecurity is not implemented directly in the arch linux kernel (it is in Gentoo).
So we are still in the same place. I'm gonna leave the link of the french forum I talked about earlier in the thread.

Does anyone has any info on what does this two commands do exactly?

gnome-session-check-accelerated
gnome-session-check-accelerated-helper

Its output is key to this issue.

I think the last update to ati-dri or mesa fixed the issue, how about you?

A_ch · 2012-06-14 20:36:01

Yes, it did!

A_ch · 2012-06-18 18:55:19

But still remains on lock-screen.
