Moving system menu bar

The system menu bar (which starts with Menu with a raspberry picture) can be moved around using right click on the empty space in the bar and selecting Panel Settings. Change the screen edge to stick it to using Edge selection under Position.

Preventing screen from going to sleep

Using the sudo and cp commands make a backup copy of the settings which are stored in a text file:

sudo cp /etc/lightdm/lightdm.conf /etc/lightdm/lightdm.conf.backup

Open the file /etc/lightdm/lightdm.conf using sudo command and nano editor:

sudo nano /etc/lightdm/lightdm.conf

Use arrows to scroll down and find line

[SeatDefaults]

and then find a following line which says:

#xserver-command=X

and change it to:

xserver-command=X -s 0 -dpms

We removed # at the beginning to active the line and set the parameters which disable screen and power saving features. Use Ctrl+X followed by Y and Enter to save the file.
