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)

If you use python via the command line in Windows vista, you’ll notice that it won’t accept command line arguments if you run a script. For example this won’t work: python myscript.py argument1 argument2 Your python script won’t get the arguments. The fix for Windows Vista is:

1. Get an application called: File Type Doctor
2. Find the .py extension in the application
3. Edit the Open action (add it if it doesn’t exist)
4. Select the right python.exe file for "the application to carry out this action"
5. put this in for the command line arguments (extactly as show, with the quotations): "%1" %*
