graphics output produces corrupt/empty files

Hi there.

as a newbie I figured out the basics of R but when it came to graphic 
output it was a bad surprise.
All but the X11 device do not function properly. Most of them generate 
an empty file and pdf() produces non valid output (gs and acroread as well).
Very annoying, because I have to write a report.
I got the recent stable binary rpm (v1.6.2) from CRAN on a SuSE Linux 8.1.
Any help?
