I got tired of looking at the matrix screensaver, it’s always green. I felt like changing the color, but there is no option provided to change the color in the preferences. I downloaded the code and made a simple one character change to make the screensaver blue.
The following is what I did
cd ~/projects mkdir xscreensaver cd xscreensaver sudo apt-get source xscreensaver sudo apt-get build-dep xscreensaver cd xscreensaver-5.08/ sudo vim xscreensaver-5.08/hacks/glx/glmatrix.c
I changed g = 0xFF on line 785 to b = 0xFF
save and exit (:wq)
sudo ./configure sudo make sudo cp hacks/glx/glmatrix /usr/lib/xscreensaver/glmatrix
Now preview your screensaver to see the results!

If you have Xming installed and are forwarding X11 with putty you may notice that all is well until you need to run a gui application as the root user (after issuing sudo su).
If you just need to run the gui application and don’t require the entire root environment then issuing a sudo app should launch your application in Xming.
However, if you do require the root environment then follow these steps.
sudo su cat /home/your_username/.Xauthority >> /root/.Xauthority
or you could do this
sudo su su - your_username -c "xauth list" > X11auth xauth add $(<X11auth)
I found this solution here: linuxquestions.org
