Lexmark demon killer

The problem with linux lexmark driver described here frequently causes my Ubuntu to freeze. While I need to use my printer I can't just remove that crap. But there is a solution- killing the demon automatically every time it runs. Don't worry, printer works even if you kill the demon.

##If you have the same problem follow the steps below:

after download move the script to more appropriate location:

sudo mv lex_killer.rb /usr/local/bin/

then give executable permissions:

sudo chmod +x /usr/local/bin/lex_killer.rb

Now you can add this to Startup Applications* by simple GUI (i'm still writing about Ubuntu). The most important field is "Command" of course, so put there:

/usr/bin/lex_killer.rb

You should also fill other fields and name it clearly so you can recognize what is this in the future.

And that's it. After restart everything should be alright.
