I installed Ubuntu 14.04 recently on my computer. After I followed this link to install Adobe pdf reader, ever time I use xdg-open to open a pdf file, there are tons of message showing on my screen:
(acroread: 31045): Gtk-WARNING **: Unable to locate theme engine in module_path: "murrine",
There are also two lines of messages:
Gtk-Message: Failed to load module "overlay-scrollbar"
Gtk-Message: Failed t0 load module "unity-gtk-module"
following this link. None of them work. The pdf files cold be opened, but these tons of warnings are annoying. could anyone tell me how to eliminate these messages?
