Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I cannot add additional toolbar buttons in Acrobat reader, it says "only available when document rights are enabled" (see the screen-shot bellow). I cannot highlight texts in pdf documents.

I have already set the permission for the document as "read and write".

I use Ubuntu 12.04 LTS and Acrobat reader 9 (installed from Ubuntu software centre)

I think it means that if the pdf document have NOT any kind of restriction than you can add those toolbar otherwise not. By the way why you have installed Adobe reader?! The inbuilt reader is much better than adobe that comes with ubuntu 12.04. –  Ravi Jun 17 '12 at 14:38

This means that these options are only available if the PDF allows you to.

A PDF has built-in permissions that are in no way connected to the "read and write" permissions of the file system. For example, a author may disallow copying of text, printing, commenting etc. regardless of said file system permissions.

You might want to use another PDF viewer as suggested.

OK, then what is the solution if I just want to highlight pdf texts in Ubuntu? It seems possible with Adode reader v10, but only v9 available to Ubuntu (there are alternative ways to view the pdf document, that is a different story) –  DUKE Jun 18 '12 at 0:51
Same document allows highlighting when opened with Adobe reader V10 (on Mac OSX), but not allow the same when opened with Adobe reader V9 (on Ubuntu 12.04 LTS). But unfortunately, Adobe reader V10 not available for Ubuntu. –  DUKE Jun 18 '12 at 4:08
Could this help you, or at least describes your problem accurately? (forums.adobe.com/message/4048304). Can you actually check the checkboxes and press OK? Or are you not even allowed to check the box? –  moewe Jun 18 '12 at 6:40
I can check the checkboxes and be able to press OK, but after doing so nothing happens (except the dialog vanishes) –  DUKE Jun 18 '12 at 11:46
Well, according to the link above this exact behaviour is an issue concerning the GTK+ libraries. There seems to be no solution on the internet as far as I could see. Maybe you want o try another pdf reader. Evince should be sufficient. –  moewe Jun 18 '12 at 14:11
