Every time I try to save a pdf from firefox, using the acroread plugin, it refuses and says "Not super User". I try to run firefox through sudo firefox, and it turns out that the super user doesn't have any display assigned or something.

Here is what it said:

sudo firefox
You should really not run firefox through sudo WITHOUT the -H option.
Anyway, I'll do as if you did use the -H option.
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified


(firefox-bin:13141): Gtk-WARNING **: cannot open display:

Anyway I think I should be able to save files without having to be root.

PD I'm trying to save in /home/julian/, which is obviously my home directory.
Also I installed acroread as described in this page: Ubuntu-EasyLinux.info

Did you try putting a copy of the plugin "nppdf.so" in your ~/.firefox/plugins directory?

-geo

I tried what you said geo, I copied nppdf.so from /usr/lib/Adobe/Acrobat7.0/Browser/intellinux/nppdf.so to ~/.firefox/plugins, which didn't exist, then I found that the real directory for plugins is ~/.mozilla/plugins, so I copied it here too, then I found that in ~/.mozilla/firefox/pluginreg.dat the path to the acroread plugin was /usr/lib/Adobe/Acrobat7.0/Browser/intellinux/nppdf.so, so I changed to ~/.mozilla/plugins/nppdf.so, but again it didn't worked.....

So I don't know where should I look to solve this issue, either with firefox or with adobe reader??


Thx anyway geo

That is very odd... I've installed Adobe Reader on countless machines, but I've never seen this kind of behaviour.

Can you save the file anywhere else? Like /tmp?
