    Hello,

    I have a laptop with integrated Intel i915 and nouveau, where the
    external monitor is connected via HDMI.

    Setup works and I have arranged the screens side-by-side. Xorg is using modesetting driver (no xorg.conf).

    I want to try GPU offloading and installed bumblebee and primus packages.

    Bumblebee blacklisted nouveau and the external screen was not detected
    anymore.

    Thats the first issue: can I still use the external monitor even though
    I have bumblebee running?

    I tried the following command to see if offloading works:

    chris@laptop:~$ primusrun glxgears -info
    primus: fatal: Bumblebee daemon reported: error: [XORG] (EE) Unable to locate/open config directory: "/etc/bumblebee/xorg.conf.d"

    That folder exists and has been created during bumblebee installation:

    chris@laptop:~$ ll /etc/bumblebee/
    total 16
    -rw-r--r-- 1 root root 3293 Nov 14 00:04 bumblebee.conf
    drwxr-xr-x 2 root root 4096 Nov 14 00:04 xorg.conf.d
    -rw-r--r-- 1 root root  513 Nov 14 00:04 xorg.conf.nouveau
    -rw-r--r-- 1 root root 1410 Nov 14 00:04 xorg.conf.nvidia

    What is the issue here? Permissions?

    Thats the second issue.

    When `primusrun glxgears` was executed, the external screen became
    active and the desktop expanded to it, although not according to my
    display setup on Cinnamon.

    Bumblebee loaded nouveau, thats why I think.

    I did not touch files in /etc/bumblebee, they look ok to me.

    What can I do to still use the external monitor as the main display, and
    get GPU offloading to work as well?

    BR, Chris
