Does anyone know if either of these printers are compatible with either Linspire, Freespire, or Ubuntu? I'm [u][b]DESPERATE[/b][/u] to switch to Linux from Windows!!!

For printer support in linux the best place to look is http://www.linuxfoundation.org/en/OpenPrinting Just look up the printer in the database and it should tell you how well it works. I have an X75 myself and the most I know of anybody getting it to do under linux is feed paper. I don't have any experience with the X1150 though.
