Hi all, 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? Thank you.
