My Ubuntu 12.04 was normally updated through the Update Manager, something about gtk. Then I rebooted and now all that shows after the splash screen is a blue screen that only shows the cursor.
I experienced the same issue. After a lot of painful efforts, solved the problem in my box.
Doing the below steps fixed the problem in my machine:
* press ctrl+alt+f1 and login as root in the tty1 * cd /usr/lib/*arch-name*/gdk-pixbuf-2.0/ * find *some-version-number*/loaders/ > ~/pixbuf-files *(not the pkg-version,try ls cmd,only one dir would list out)* * vim ~/pixbuf-files and delete 1st line * cat ~/pixbuf-files | xargs -n1 gdk-pixbuf-query-loaders > *the-version-number-in-step-3*/loaders.cache * reboot
in my case:
* press ctrl+alt+f1 and login as root in the tty1 * cd /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/ * find 2.10.0/loaders/ > ~/pixbuf-files * vim ~/pixbuf-files and delete 1st line * cat ~/pixbuf-files | xargs -n1 gdk-pixbuf-query-loaders > 2.10.0/loaders.cache * reboot
