[Heikki Wilenius <heikki.wilenius@xxxxxx>]

I'm replying to Peter's old email, since I finally managed to figure
out how to dedicate a separate set of keyboard & mouse for the
external screen. The answer has appeared in the Bumblebee wiki:
https://github.com/Bumblebee-Project/Bumblebee/wiki/Multi-monitor-setup.
This way you can use the touchpad and Vaio keyboard for the laptop
screen, and external keyboard and mouse for the external screen. Since
the keyboard & mouse do not use an emulation layer (x2x or synergy),
it works even with gaming and other full-screen applications.

The answer is ingeniously simple: just use xinput to disable the
duplicate input devices with a script.

Unlike the script author, I used device IDs instead of device names in
my script, since I had duplicates in my xinput list.

I've attached my launch script and my xorg.conf.nvidia file below.

Cheers,
Heikki

the launch script:

#! /bin/bash
# Starts a separate X session using Optimus
# and uses separate input devices for each
# must be run as root, with 'optirun'

if [[ $EUID -ne 0 ]]; then
   echo "This script must be run as root" 1>&2
   exit 1
fi

# First, disable external inputs on internal screen's X server
# Replace these with the names of your EXTERNAL input devices.
xinput disable 11
xinput disable 13
xinput disable 14

# Set display ID to the external screen's X server
DISPLAY=':8'  #<-- This should be the value of 'VirtualDisplay' from earlier.
LD_LIBRARY_PATH=/usr/lib/nvidia-current:$LD_LIBRARY_PATH

# Disable internal inputs
# Replace these with the names of your INTERNAL input devices
xinput disable 16
xinput disable 15

# Start another session.  This example is for XFCE or Xubuntu, look up
the appropriate
# command for your desktop environment of choice and replace
'xfce4-session'. (I used awesome /heikki.)
# Remember to replace USERNAME with your username.
su -c awesome USERNAME > /dev/null 2>&1
