Create a New Terminal with a Title from Shell

gnome-terminal --working-direcotry=(mydirectory) - t "MyTitle"

to make sure the title works, edit /root/.bashrc to comment out the line that sets title of a terminal

case "$TERM" in
xterm*|rxvt*)
    #REMOVED because it makes commands to title() not work  
    #PS1="\[\e]0;${debian_chroot:+($debian_chroot)}\u@\h: \w\a\]$PS1" <-- remove

Dual Monitor Settings

Set external monitor as the primary monitor
xrandr --output VGA1 --primary
xrandr --output VGA1 --auto --pos 0x0 --output LVDS1 --auto --below VGA1
after that use the monitor settings to adjust position

going back to laptop screen only
xrandr --output VGA1 --off --output LVDS1 --auto

Given that I'm using a laptop and my laptop screen identified as LVDS1 and the external monitor as VGA1, I set up three icons that run a script, to switch between clone, dual with LVDS1 as primary, and dual with VGA1 as primary.

Using the text editor Kate I created three files with the names:
VGA1-Primary.sh
LVDS1-Primary.sh
Clone-Monitors.sh

The text contents of VGA1-Primary.sh are:
xrandr --output VGA1 --right-of LVDS1
xrandr --output VGA1 --primary


The text contents of LVDS1-Primary.sh are:
xrandr --output LVDS1 --left-of VGA1
xrandr --output LVDS1 --primary


The text contents of Clone-Monitors.sh are:
xrandr --output LVDS1 --auto --output VGA1 --auto --same-as LVDS1

enable disable touchpad

Method #1
xinput list gets the name of the touchpad... for me it's "PS/2 Generic Mouse"

then white this shell script on desktop
#!/bin/sh
DEVICE="PS/2 Generic Mouse"
if [ `xinput list-props "$DEVICE" |awk '/Device Enabled/ { print $4}'` -eq 0 ]; then
xinput --set-prop "$DEVICE" "Device Enabled" 1
else
xinput --set-prop "$DEVICE" "Device Enabled" 0
fi

Method #2
disable: modprobe -r psmouse
enable: modprobe psmouse
