I did not know that one can have blue screen in ubuntu as well. But if you know it already that don’t panic, this is how to fix blue screen in ubuntu. It is probably happened because of problem in upgrading distro.
$ sudo su
$ sudo apt-get install libgdk-pixbuf2.0-dev
$ cd /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/
$ find 2.10.0/loaders/ > ~/pixbuf-files
$ nano ~/pixbuf-files
# and delete 1st line 2.10.0/loaders/
$ cat ~/pixbuf-files | xargs -n1 gdk-pixbuf-query-loaders > 2.10.0/loaders.cache
