Hello, On the Mac I use TkAgg and can output PDF files no problem. The only reason I was using GTKCairo was to get the PDF output which was not working with GTKAgg. I just updated to the most recent SVN from the one I was using from earlier today and now I can save to PDF in GTKAgg without troubles. Basically I just wanted something that was interactive till I made the plot to my liking then I could save the figure to a PDF. On the mac this worked with TkAgg without any troubles and now on Linux it works iwth GTKAgg without any troubles. Not sure what changed but thanks for the help.
