The Matrix Is Blue

by Lalit Kapoor on 2010-01-202010-01-21T02:07:39ZY-m-d">January 20, 20102010-01-21T02:07:39ZF j, Y

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!

X11 Forwarding When Issuing: sudo su

by Lalit Kapoor on 2010-01-082010-01-08T13:36:25ZY-m-d">January 8, 20102010-01-08T13:36:25ZF j, Y

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

Does your laptop squeal? Is it a nasty high pitch noise that occurs when you are running on battery power.

Python Won’t Take Command Line Arguments – Windows Vista

2008-12-212008-12-21T15:29:56ZY-m-d">December 21, 20082008-12-21T15:29:56ZF j, Y

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:

Get an application called: File Type [...]

Problem

Discussion

I have an old T43 laptop by IBM. Recently I put Ubuntu 8.04 (Hardy) on it and started getting a hissing noise when running on battery power. I found 2 possible solutions:

add the following to /etc/modprobe.d/options

options processor max_cstate=2

get the linux-server kernel

sudo apt-get install linux-server

I didn’t get a chance to try the first option as I [...]
