Nah. Scalix (damn good email server package, would be better in some cases) requires RedHat or a close clone. Boss likes Ubuntu anyway, and I agree -- Ubuntu is much eazier. I haven't run into a problem with it lately (it's just Debian I have problems with).

Infraread, you need to install irda-utils and find out what chipset is being used for IrDA so you can recompile the kernel with drivers for it.
