Just about
every manufacturer on a stage puts its name in large
letters. Korg, Roland, Yamaha, Nord, etc... Although 'Linux'
is not a musical instrument/software manufacturer, why not
neverthless simply put its name in large, perhaps somewhat
stylized/coloured, letters ? Or somewhat smaller letters offset
from a top corner of the laptop's cover ?
If you put "Linux" on there in big letters, you also need the /small
print/ : "Linux is a Registered Trademark of Linus Torvalds."
anyway it should be "gnu/Linux" - and you might get away with it..
Surely there are no laws anywhere in the world that prohibit mentioning
or displaying a trademark without also saying who owns it?
