For those of you who would like to experiment with a Linux screensaver, try "sudo apt-get install xscreensaver" in evilvte.
If all goes well, xscreensaver should appear under Preferences on the Panel Menu.
You may want to install jiongtang's screen rotation utility script as well (go to
http://www.jiongtang.com/blog/html/category/smartq5 and scroll down to the link for the firmware you're using). Of course, the Q5 script has been tested on the Q7 and runs fine.
The jiongtang screen rotation tool will allow you to see the entirety of some xscreensaver screen options on the Advanced tab like Text Manipulation and Fading and Colormaps, which otherwise fall off the bottom of the screen.
The Advanced tab also allows you to take control of the Power Management on the Q7 with settings for Standby, Suspend, and Off.
I'm using the Sonar screensaver as my current default.
What's your favorite screensaver?
