1. Create a bash script with the following contents

#!/bin/bash
VirtualBox -startvm NameOfYourVirtualOS

Replace yourSUPassword with your password, and NameOfYourVirtualOS with the name that you have given to your virtual OS in VirtualBox.

2. Name it something like windowsXPGDM (if you want to run Windows XP), make it executable, and then copy it to /usr/bin.

$ chmod 755 windowsXPGDM
$ sudo cp windowsXPGDM /usr/bin

2. Go to /usr/share/xsessions and create a new file with the following contents:

[Desktop Entry]
Encoding=UTF-8
Name=WindowsXP
Comment=My Virtual WindowsXP
Exec=/usr/bin/windowsXPGDM
Icon=
Type=Application

3. Save it with a name something like windowsXP.desktop.

4. Log out and you will see a new entry WindowsXP in your GDM session. You can now directly open VirtualBox session without even logging in to your Ubuntu machine.

1. I always backup my /etc/X11/xorg.conf file to something like /etc/X11/xorg.conf.bckup
2. When something is broken, I often find that my xorg.conf file has been modified. To find out whether there is any modification, I issue:
   stat /etc/X11/xorg.conf
3. If there is any, I list the changes:
   diff /etc/X11/xorg.conf /etc/X11/xorg.conf.bckup -y –suppress-common-lines
4. I then undo the modifications. Those who aren’t comfortable with command lines can try meld. It is a graphical frontend for diff command. It couldn’t be more easier to merge/remove changes in two versions of same file. It is in the Universe repository so you should get it by issuing:
   sudo apt-get install meld
5. After the modifications have been undone, I restart Hardy. Most of the time I get my xserver fixed with everything working fine – color depth, screen resolution etc.
6. If restarting the system does nothing other than greeting with that dialog box – Ubuntu is running in low graphics mode, then i try to reconfigure xserver by issuing:
   sudo dpkg reconfigure xserver-org
   It will ask you a couple of questions, clicking on default option will be OK
7. After it gives a ’successful’ message, time to restart. I can see the changes immediately – login screen spanning to my whole screen.
8. I need to enable the drivers for my card by going to System>Administration>Hardware Drivers
9. Finally, enabling my nvidia card, restarting once again and going to System>Preference>Screen Resolution to set the correct resolution, gives my pretty looking xserver back again.
10. The next important task is to create the backup of my /etc/X11/xorg.conf file again.

5. Look for following lines:
   Section “InputDevice”
   Identifier “Synaptics Touchpad”…
   …
   EndSection
6. Add the following line just before the line EndSection
   Option “SHMConfig” “true”
7. Save the file
8. Open a Terminal
9. Type the following command
   syndaemon -d -t -i 5
   -d runs the command in background
   -t disables only tapping and scrolling but not mouse movements
   -i sets the idle time in seconds after the last key has been pressed. The default is 2 seconds. I was convenient with 5 secs. It means if I don’t press any key for 5 secs, the touchpad will be enabled.

Now to run make the command as a startup command follow the following steps:

1. Go to System>Preference>Sessions
2. Click on Add button.
3. Fill up the following data in the dialog box that appears:
   Name: { Name of the command such as: Disable Touchpad }
   Command: syndaemon -d -t -i 5
   Comment: { Any comments such as: Disables touchpad’s tapping functionality while typing }
4. Click on OK and Close the Sessions dialog box

Enjoy tapping less typing
