My PC is an Intel i5 with HD4000. Drivers loaded and all running fine.
I've added the machine to a Windows Active Directory and when logging with an Active Directory user the Cinnamon desktop runs in Sofware rendering mode, despite I select don't in GDM.
Why is the reason for that? How can I solve it?
It's using always a 30-40% of CPU...
While logging with a local user seems all fine, Cinnamon without soft. rendering and CPU between 0 - 5 % because of background processes, not Cinnamon desktop.
