I have a Dell Latitude E6430, with the Optimus thing and a dual graphic
card: Intel & Nvidia.
(I did know I got that until now)
I installed bumblebee and bbswitch
I enabled bumblebeed at startup
I installed "intel" and "nouveau" Xorg drivers
I setup nouveau to be early loaded
The BIOS only allow me to check or uncheck "Optimus".
When unchecked => The OS boots with Intel ("intel" driver)
when checked => The OS boots with Nvidia ("nouveau" driver)
To potentially enable the 2 cards, I have to setup "check" that option.
When this option is checked (the system boots on the Nvidia card)
"xrandr" only lists 1 provider: nouveau.
I cleaned /etc/X11/xorg.conf or /etc/X11/xorg.conf.d/* to not mention
any GPU related instructions.
I get stuck on this, because whatever documentation I read, as long as
xrandr lists only 1 provider I cannot try any solution to get 3 screens
when I want to (I use a xrandr GUI to enable what I want).
Note that I dont want to have 3 screens all the time.
Where should I check further in order to get xrandr to list the 2
poviders I need?
