Relationship of gnome-shell and mutter

[Kevin Master <kevinliuwt yahoo com>]

Dear,

i have a question about gnome-shell on my Debian Jessie OS.

I follow the Debian official way to install Gnome desktop:

tasksel install gnome-desktop --new-install

Everything goes smoothly, until i use lightdm to start gnome session, 

all the applications displays corrupted window. I found that mutter is

not starting up as the window manager.

My gnome-session file looks:

        Name.......

        RequiredComponents=gnome-shell;gnome-settings-daemon;

I tried to add mutter to the gnome-session RequiredComponets group, 

but it also fails.

 

I  have 2 questions here:

• Should mutter also start to support gnome-shell working ?
• Where the composite happens, in gnome-shell process or in mutter process ?

Thanks.

 

Best Regards

Kevin
