Hi Rolf,
please excuse a short "top-reply":
As I see you are using an operating system (instead of Win..),
can you try in the shell
echo 'X11.options()$type' | R --vanilla --slave
Martin,
given the R on my non-OS had X11.options, I'd rather written:
R --slave --vanilla -e "X11.options()$type"
Don't know why you have to type more on your OS.

and does that really *not* report
[1] "cairo"
??
(and BTW: Your subject had tolower("LL") instead of "11" )
