Xubuntu - Change Icon of a program / launcher on the desktop

You have some icons on your desktop you want to change?








You can right-click on it but there is no "change icon" selection.

Ok. Right-click it again.
Choose "Properties".

On the left there is a Icon.
Click it!

Now you can change the icon.

(I was looking everywhere until I find this. Now (because I know) I think it's so easy!)

Can't disable a Screen-saver under Xubuntu

Watching a movie and suddenly it switches to a black screen. It's anoing.

The Screen-saver was disable by the way and so was the Power Manager.

Open terminal and type:

xset q

You can see a list of information including some infos about "Screen Saver".
Does it say "prefer blanking YES"?

There is the problem.

You could set it of with "xset s noblank". But after reboot it does it again.

The solution is to put the following line into a "Application Autostart" call.

bash -c "xset s noblank; xset s off"
