I was not aware that there was such a good support for Lightscribe on Ubuntu. I have had Lite-on Lightscribe installed on my desktop for a year but never used it. (did not have enough curiosity until today). Initially I was reading an article on how drivers could be found easily on LaCie but then I found this write up on Ubuntu itself.
Get the 3 deb packages…
1. LightScribe System Software
2. LightScribe Simple Labeler.
3. LaCie 4L Labeler utility
Install the deb packages and use the following commands..
To run SimpleLabeler
To run the LaCie 4L application
