[Brando]

My computer is being used as a server (Xorg) and they are preventing me from freely using my devices. I saw in other computer that they are manifacturing certificates, i struggled to get this ubuntu pro, and now they say i have an administrator for my account for whom i need to ask permision to get a kernel patch. Plz help me.

They are keeping me from working and doing whatever, they are truly terrorizing me (wont get into 2 much detail but they show me scary stuff and sounds, for a month i thought i was cursed or something). I tried many things, i have reinstalled ubuntu, lubuntu, kubuntu, many times, but they seem to catch every attempt and swap the original iso for a cheap copycap with many bugs. When i try to hard to keep them out, they either do something to say that my disk is full, or wont let me succesfully do any command line. How do i get out of this nightmare though?
