put into .bashrc:

. ~/.profile

usable for xmonad

/usr/include/X11/keysymdef.h
/usr/include/X11/XF86keysym.h 

For video control install xrandr

$ sudo apt-get install xrandr

For audio control install pulseaudio

$ sudo apt-get install pulseaudio

In /etc/pulse/default.pa, replace load-module module-stream-restore with load-module module-stream-restore restore_device=false

Then to toggle between output use the toggle_video or toggle_audio scripts respectively.

Or install gui tools as an easy alternative or if the scripts fail:

$ sudo apt-get install arandr
$ sudo apt-get install pavucontrol

@see http://askubuntu.com/a/149427

To permanently set swappiness to X (1-10 should be good, while default is 60):

sudoedit /etc/sysctl.conf

Add this line:

vm.swappiness = X

Restart system

sudo shutdown -r now

   KERNEL=="event[0-9]*", SUBSYSTEM=="input", SUBSYSTEMS=="input", ATTRS{name}=="DualPoint Stick", SYMLINK+="my_mx_mouse", GROUP="mxgrabber", MODE="640"

2. create /etc/udev/rules.d/

4. add to /etc/modules-load.d/uinput.conf

   uinput
