Known Issues with Adobe Reader 8.1.1

This page lists the known issues with Adobe Reader 8.1.1 for Linux and Sparc Solaris platforms. These issues have been logged as bugs internally at Adobe, and are being tracked. If you have encountered an issue that you do not see listed here, please add a comment to this page with your issue and we shall review and incorporate the same. Also, there may be workarounds to address your problem and the issue may have already been discussed on the user to user forums.

  1. shrink and expand options in -toPostScript command line options do not work
    The -shrink and -expand suboptions when given with the -toPostScript command line option do not work – these options have no effect on the scaling property of the generated postscript file.[FIXED IN ADOBE READER 8.1.2]
  2. JavaScript getField.display call fails on a non-form-rights-enabled document when called in page-open /PO event
    The JS fragment:
    f = getField(name)
    f.display = display.hidden
    f.display = display.true
    With Adobe Reader 8.1.1 the fragment fails when run in a page-open /PO event, unless the PDF is forms-enabled.
    But the fragment works in a non-forms enabled PDF for all the other events: mouse down, mouse up, mouse enter,
    mouse exit etc.
  3. Animation files with Optional Content Groups (OCG) run slow
    PDF files with animated graphical content containing Optional Content Groups, controlled using embedded JavaScripts, run with slow jerky movements in Adobe Reader 8.1.1.
  4. Problem with Dual-screen setup (Xinerama mode)
    When used under dual-screen setup, maximizing the Acroread window leaves the contents of the page unchanged, whereas the window is maximized.[FIXED IN ADOBE READER 8.1.2]
  5. Wrong Minimum GTK version for Solaris in the ReadMe
    Adobe Reader 8.1.1 for Sparc Solaris requires a minimum GTK version 2.6. However, the ReadMe incorrectly specifies GTK 2.4 as the minimum requirement. For more information on updating the GTK libraries on Solaris, please refer point no. 8 in the Adobe Reader 8.1.1 FAQs.[FIXED IN ADOBE READER 8.1.2]

Adobe Reader 8.1.1 FAQs

This page attempts to answer some of the Frequently Asked Questions related to Adobe Reader 8.1.1 for Linux and Sparc Solaris. If your specific question is not answered here, please post a comment with your question and we will try to address your query.

  1. Is there a version available for Solaris x86 platform?
    Adobe Reader is currently available on the following flavors of Unix: Linux (8.1.1), AIX (7.0.9), HP-UX PA-RISC (7.0.9) and Sparc Solaris (8.1.1). There is currently no version available for Solaris x86 platform. Adobe shall let the user community know in case there is a plan to support Solaris x86 in a future release.
  2. On starting acroread, a dialog box pops up “Unable to find the HTML rendering library (libgtkembedmoz).”

    This happens if acroread was unable to find and related component files on your system.

    GNOME Help (aka Yelp) also uses these libraries for displaying the HTML content. To find out if your system has, check the output of the following command:

    ldd `which yelp` | grep libgtkembedmoz

    If this returns a valid folder name, set the Adobe Reader preference at “Preferences > Internet > libgtkembedmoz Folder” to the returned folder name (see screenshot below). If this does not work for you or your desktop environment is non-GNOME based, then try one of the following:

    • Check to see if you have XULrunner installed (you can install the latest XULrunner from here), and find the folder containing in the XULrunner installation. Set this folder in the “Preferences > Internet > libgtkembedmoz Folder” preference in Adobe Reader.
    • Check to see if you have Mozilla web-browser installed. Make sure the Mozilla installation is based on GTK 2+ (you can install GTK 2+ based Mozilla from here). Find the folder containing in the Mozilla installation. Set this folder in the “Preferences > Internet > libgtkembedmoz Folder” preference in Adobe Reader.
    • For debian based distributions you can install libxul0d from here, and find the folder containing in the libxul0d installation. Set this folder in the “Preferences > Internet > libgtkembedmoz Folder” preference in Adobe Reader.

    If you’re still not able to fix this, please post a comment to this page with the details and we will try to help you. Also refer FAQ item no. 10 below.

    Note: On 64-bit systems you need a proper installation of 32-bit XULRunner, Firefox or Mozilla. Copying only 32-bit is not sufficient.

    libgtkembedmoz setting in the preference pane

    [This launch-time Alert has been suppressed in Adobe Reader 8.1.2]

  3. What is and why does acroread need this library? is used by acroread to render HTML content within the user interface elements, including the Beyond Adobe Reader page, the HowTo panels and the Adobe Help Viewer.
  4. I found a potential bug in Adobe Reader 8.1.1. How should I report it?
    Please first take a look at the known issues page. If you do not find the entry there, please post a comment on that page with your issue. We will add your entry to the list of known issues, and register a bug to track the problem. However, there may be workarounds available, so do please check out the user to user forums as your query may have already been answered there by a fellow user.
  5. Which Linux distributions does Adobe Reader 8.1.1 work on?
    Acroread works on a large range of linux distributions, some of which have been used for testing at Adobe and others by customers. Refer the system requirements page, and the page which lists the supported linux distributions.
  6. Does Acroread run on 64-bit systems?
    Acroread is currently a 32-bit program and it will run on 64-bit systems in emulation mode only. If you desire to run acroread in emulation mode, make sure that all the required dependencies of acroread (such as GTK,, browser, etc.) are 32-bit. Acroread does not work with 64-bit binaries or libraries.
  7. Browser plugin doesn’t load on Linux
    If SELinux security is turned on, the browser plugin ( as well as PPKLite plugin (PPKLite.api) doesn’t load because these are not SELinux compliant. To fix this you can run the patch for SELinux which is shipped along with Adobe Reader 8.1.1 kept at acroread_install_dir/Adobe/Reader8/Reader/Patch/selinux_patch.

    Run this patch script as follows:

    ./selinux_patch acroread_install_dir/Adobe/Reader8

    with root privileges.
    Note of caution: This will disable SELINUX enforcement for all the libraries of Adobe Reader 8.1.1

    [This issue has been fixed in Adobe Reader 8.1.2]

  8. Adobe Reader 8.1.1 doesn’t launch on Solaris
    By default, Solaris 10 comes bundled with GTK 2.4.9, whereas Adobe Reader 8.1.1 requires a minimum GTK version 2.6 to run properly (refer point 5 on the Known Issues Page). So if you try to run acroread on such a system you may observe a host of GTK related warnings on the console and acroread may not launch. To fix this issue, you can update the GTK version on the Solaris machine (read the steps below for one way in which the GTK libraries can be updated easily).

    Updating the GTK Libraries on Solaris, from

    1. You need pkg-get on your system. If you do not have pkg-get, you can install it using the following command:
      pkgadd -d
    2. Edit the pkg-get configuration file in order to download from the nearest mirror ( lists all mirrors at:
      vi /opt/csw/etc/pkg-get.conf
    3. Install the wget package (along with all its dependencies) using pkg-get
      /opt/csw/bin/pkg-get -i wget
    4. Install gtk+ using pkg-get
      /opt/csw/bin/pkg-get -i gtk2
    5. Set the LD_LIBRARY_PATH appropriately before running acroread
      export LD_LIBRARY_PATH=/opt/csw/lib:$LD_LIBRARY_PATH

    PS: The above listed method is just one way of updating the GTK libraries, and other methods may exist. Irrespective of the method used, before launching acroread, remember to set the LD_LIBRARY_PATH appropriately to the directory which contains the correct GTK libraries.

    [This issue has been fixed in Adobe Reader 8.1.2]

  9. Why does show up in the process list, instead of acroread?
    On non-LSB compliant Linux distributions, acroread launches the default linux loader ( This is why you see the name ‘″ in the process list instead of acroread. This should have no effect on the working of the acroread program.
  10. On starting acroread, a blank window titled “Beyond Adobe Reader” pops up.
    Try running acroread from the command line and check for any warnings messages on the console. If you see gtkembedmoz related warning messages, it means that you don’t have the required Mozilla installation. For more details you can refer the FAQ item no. 2 above.
  11. Can I set the libgtkembedmoz folder preference globally, for all the users?
    Yes, this preference can be set globally for all the users .To do so,

    1. Create a file named mozilla_config in <Installation_dir>/Adobe/Reader8/Reader/GlobalPrefs/.
    2. Write MOZILLA_COMP_PATH=<location of> in this file and save it.
    3. In the acroread script, located at <Installation_dir>/Adobe/Reader8/bin/, search for the section “Enable this if you want to set MOZILLA_COMP_PATH globally”, the section would be commented out, removes the #s, and save the file.

    Now all the users should be able to see the html contents without setting libgtkembedmoz folder preference individually.
    Note: In case you want the global preference to override users’ preference, then move the section mentioned above just before the following line in the acroread script:

  12. Unable to print secured files on Ubuntu Gutsy (7.10)
    Are you on Ubuntu Gutsy (7.10) and printing to a non PostScript printer? If yes, please check the GhostScript version on your machine. If it is “8.61 pre-release”, download the sources of the official release version 8.61 and build it using the standard configure/make/install method. That should fix the issue. The issue occurs as GhostScript is bundled as a shared library with Gutsy. The Ubuntu Gutsy engineers are aware of this issue and are tracking it through this bug. Refer to the original GhostScript bug for details.
  13. Unix Reader unable to act upon .etd files
    Unix Reader 8.x does not support eBooks plugin, and therefore does not support viewing eBooks. This is supported in Reader 8.x on Windows and Macintosh platforms. Note that Reader 9 for Windows and Mac too have removed support for the .etd eBook format and instead redirect to Adobe Digital Editions if it’s installed on the user’s system. Digital Editions is not currently available on Unix platforms. For more information on Digital Editions, please refer
