Trisquel is installed on my USB stick from the live DVD.
I boot from the USB stick drive and run Trisquel from there.
That's not the problem...
The problem is accessing files on the hard drive partition. I can read them.
I can even save them as something else if I do modify them. But I cannot
modify the existing files and save the changes. Trisquel says I do not have
permission to do that.
How to use this "su" and "sudo" password (if that is in fact the case)
business to get my way with my own freakin' files?
