I only have one ubuntu (mint / gnome) system, but if you install xCHM you can open the .chm file and then Print it to .ps (postscript) or install a 'print to pdf' app.. (in SuSE (openSuSE) / KDE i use cups).
open the .ps file in your pdf reader and either print to or 'save copy as' *.pdf.
if you can install or have installed a 'print to pdf' app, you're done after opening in xCHM and 'printing'...
hope this helps.
