Other observations

1. The touchpad (black square at center of laptop that helps to move the mouse) is having a soft LEFT and RIGHT button (not working correctly)
• To drag windows, press bottom half of the Touchpad until a click is felt. Then drag without leave finger from the Touchpad.
• To RIGHT click in window, you need to press bottom half then do a second click without lifting the first finger.
• Install from (HP) or better still to use a mouse pointer.
2. Music
• Default "Totem Music Player" doesn't support MP3. Need to install gstreamer-plugins-ugly
3. Webcam
• Runinng "Cheese" I can adjust to higher resolutions but its frames per seconds is very little. This causes the video to seem very poor quality. 
4. Option to edit the menu bar (add new items manually) is missing. Installed alacarte package, logout then back in to enable editing of menu items.
5. If boot was to only command line (a black screen), switch to graphical. Type init 5.
