Second GDM session crashes when changing console

[schleudertrauma81]

Hi guys,

I'm working with 2 XFCE sessions using the configuration below:

[daemon]
DefaultSession=xfce.desktop

[greeter]
GraphicalTheme=Gentoo-Grey-GDM
GraphicalThemes=applegentoo
Use24Clock=automatisch
GraphicalThemeRand=true

[servers]
0=Standard
1=Standard

It's working fine in tze first place. GDM automatically starts 2 sessions and I can log in with 2 different users at the same time. Unfortunatelly when switching sessions (CTRL+ALT+F7/F the F8-session crashes and everything I get to see is a black screen with a blinking cursor in the left upper corner.

Does somebody have an idea how the issue can be fixed?

Thanks a lot in advance.

Cheers
Daniel
