I have downloaded and installed a new theme before in my fedora machine.

However, I got this warning when I load gvim, nautilus every time.

(gvim:4629): Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine",
(gvim:4629): Gtk-WARNING **: Unable to locate theme engine in module_path: "equinox",

How can I download this theme engine?? and remove this warning?

On Ubuntu 13.10 the command i needed was:

sudo apt-get install gtk2-engines-murrine:i386

I know the question is about fedora but I ended up here where one of the answers pointed me in the right direction.

Just in case it would be helpful to others.

  • works on 64 bit too

If it's unable to find the engine, it means you haven't installed them yet. Simply do someting like this:

sudo yum install gtk2-engines gtk-murrine-engine gtk-equinox-engine
  • this is a correcter answer as the other one doesn't say anything about the murrine or equinox engine

    Packages are named gtk2-engines-murrine and gtk2-engines-equinox for some distributions. Apr 3, 2013 at 21:53

    it is "gtk2-engines-murrine" in ubuntu. Perhaps you should also consider installing "murrine-themes"

Install gtk-engines package from your distro's repository. If there's not a gtk-engines package, search for a package with a similar name, you shall find one.

For ubuntu the package name is gtk2-engines. You may need to reinstall the package:

$ sudo apt-get install --reinstall gtk2-engines
  • I am using fedora, how can i Download that from distro? I am a linux new bie :(

  • AFAIR, Fedora uses Yum to get packages, if so, try running "yum install gtk-engines" from your terminal.

  • Alternatively, try downloading an rpm package for your architecture from here: fr2.rpmfind.net/linux/rpm2html/search.php?query=gtk-engines and install it using "rpm -i <package-name>".

  • i reinstalled (with the mentioned command), and the error repeated. (i'm actually trying to run a Qt4 on Mint 17) Dec 21, 2015 at 13:32

People experiencing this problem with, eg Acrobat Reader on 64bit installs should try this:

sudo apt-get install gkt2-murrine-engine:i386

  • could u elaborate Usage of gkt2murrine engine? Aug 30, 2013 at 7:58
  • I've no idea what it does under the hood, just that Acrobat Reader complains if it's missing, and doesn't if it's present. There are accounts of problems with older versions of vmware-player requiring gtk2-murrine-engine as well. Sep 1, 2013 at 2:15
  • I think the key for me was gtk2-engines-murrine:i386 and gtk2-engines:i386 . Ubuntu 18.04 running Acrobat Reader 9.5.5 so fillable PDFs work.

If none of the other answers solved your problem, you can also try

sudo apt-get install libgtkmm-2.4-1c2a libgtkmm-2.4-dev

This worked for me (Ubuntu 14.04 x64, Gnome 3.12). I already had the gtk2-engines-murrine installed (both i386 and x64), and changing the GTK_MODULES didn't do anything for me.

  • Thank you. I had the exact same problem and this solution worked like charm

I installed sudo apt-get install libgtkmm-2.4-1c2a libgtkmm-2.4-dev But gives that error again.Then I download murrine-0.90.3.tar.gz and

tar -xvf murrine-0.90.3.tar.gz
cd murrine-0.90.3
make install

now works. no errors.hope this helps someone.


How about installing package gnome-themes-standard. Try sudo apt-get install gnome-themes-standard or similar command in the corresponding way depending on what linux package management used.


This worked for me: Using Synaptic, search for 'gnome-themes' As a side-effect that will also list an entry gtk2-engines So just install gtk2-engines, i.e. Mark for installation and Apply


For Ubuntu 20.04, it is sudo apt-get install murrine-themes to solve the warning.


The following command is what I needed to solve this problem on Arch Linux.

sudo pacman -S gtk-engine-murrine
