Comment 28 for bug 1174253

Don't have the libglib package list from before the ppa-purge, output went beyond my terminal buffer before I copied this down. But pretty much all the libglib files were from the webupd8 ppa.

These are the steps I took on the machine I found this on originally, which worked. Thank you! Still have to attempt this on another machine. Probably won't be until Sunday though.

$ sudo ppa-purge ppa:webupd8team/gvfs-libmtp
... lots of removed and downgraded packages ...

$ dpkg -l | grep libglib
ii libglib-perl 2:1.241-1 interface to the GLib and GObject libraries
ii libglib2.0-0 2.32.1-0ubuntu2 GLib library of C routines
rc libglib2.0-0:i386 2.35.4-0ubuntu5~webupd8~precise1 GLib library of C routines
ii libglib2.0-bin 2.32.1-0ubuntu2 Programs for the GLib library
ii libglib2.0-cil 2.12.10-2ubuntu4 CLI binding for the GLib utility library 2.12

ii libglibmm-2.4-1c2a 2.32.0-0ubuntu1 C++ wrapper for the GLib toolkit (shared libraries)

# Didn't quite get it all...
$ sudo apt-get purge libglib2.0-0:i386

Reboot, still black screen, no icons...

$ sudo /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders --update-cache

Reboot, success!
