[lxc-users] nvidia graphics support in lxc (2.0, ubuntu 16.04)

[Oz Dror]

I upgraded the container to 16.04 and reinstalled upgraded nvidia-364 in
both. I have also used the cuda package from the Ubuntu repo.

i.e apt-get install nvidia-cuda-toolkit   (version 7.5)

Now I have graphics, but I do not have keyboard and mouse.

adding the following does not help. Because 16.04 is missing the xorg kbd
and mouse packages.

Section "ServerFlags"
        Option "AutoAddDevices" "False"
EndSection

Section "Device"
    Identifier  "DiscreteNvidia"
    Driver      "nvidia"
    VendorName  "NVIDIA Corporation"
EndSection

Section "Screen"
   Identifier "Default Screen"
   Device "DiscreteNvidia"
EndSection

Section "ServerLayout"
    Identifier     "Desktop"
    InputDevice    "Mouse0" "CorePointer"
    InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
    Identifier "Keyboard0"
    Driver "kbd"
EndSection

Section "InputDevice"
    Identifier "Keyboard0"
    Driver "kbd"
EndSection

Section "InputDevice"
    Identifier "Mouse0"
    Driver "mouse"
    Option "Protocol" "auto"
    Option "Device" "/dev/input/mice"
    Option "ZAxisMapping" "4 5 6 7"
EndSection
