Try this. Start Firefox from a command prompt: LD_PRELOAD=/usr/lib/libXt.so.6 /usr/lib/firefox/firefox
That should temporarily fix the problem until you exit firefox. The problem appears to be that nppdf.so expects that libXt.so to already be loaded, which is bad practice. A hack that will work around the problem (but load more, possibly unnecessary libraries, depending on what you're doing), again at a command prompt: 1) sudo cp -a /usr/lib/firefox/firefox /usr/lib/firefox/firefox.old 2) sudo vi /usr/lib/firefox/firefox 3) search for: export LD_LIBRARY_PATH 4) change it to: export LD_LIBRARY_PATH LD_PRELOAD=/usr/lib/libXt.so.6 export LD_PRELOAD Save the file and make sure firefox is completely closed. When you start up Firefox the next time, you should find that Acrobat reader works, at least until an update comes out that overwrites the firefox script. -- nppdf.so: undefined symbol: XtCalloc https://launchpad.net/bugs/41787 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
