Okay so I got Linux installed on my Dell laptop back in January of this year, and I am loving it so far! However, today I was letting it run some updates and without thinking I just shut down my laptop so I could go to work. Upon returning home I went to boot up my laptop and an error message popped up...I didn't think much of it at the time so I tried opening up Firefox, and an error message came up saying Server not found Firefox can't find the server at start.ubuntu.com. I also looked at my desktop and saw that it looked unusual as well. Where my icon for Skype and Steam were normally were replaced with Icons with a red circle and a line through it. And when I logged out of my laptop another whole error message came up.
(process:1892): GdkPixbuf-WARNING**: Cannot open pixbuf loader module file '/user/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache': No such file or directory this likely means that your installation is broken. Try running command gdk-pixbuf-query-loaders>/user/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache to make things work for the time being.
(process:2050):GdkPixbuf-WARNING**: Error loading xmp image loader:Image type xpm is not supported glmatrix: unable to initialize builtin texture xscreensaver:12:45:41 0: child pid 2059 glmatrix exited abnormally (code1)
I tried entering the command to try and make things work but it didn't when i entered it in it just came up as not found or error. I really honestly don't know what to do anymore and most sites on google aren't helpful at all. I hope I am descriptive enough, and I am hoping someone on these forums could help...I'd greatly greatly appreciate it. Thanks guys!

Do you have libgdk-pixbuf2.0-dev installed?
Try that and see if that works for you, I searched around and found a few upstream bugs, but you just may have to update the cache (of course after verifying that package is installed). As far as the error when you ran the command it gave you, what was the exact error?

Ninja edit: If you can, try to come up with a more descriptive title next time, as 'help me please' doesn't describe anything. Most people here will not even look at your thread because of the title, just trying to help!

For the error when I ran the command it gave me it said "Command not found"

As for the code you gave me, I typed it in the Terminal and it gave me this.

E: Could not open lock file /var/lib/dpkg/lock - open (13: permission denied)
E: Unable to lock the administration directory (var/lib/dpkg/), are you root?

I gave them my password thinking that is what it needs but it also came up with command not found.

Sorry if I seem stupid with this I am fairly new to Linux, is there any other help you could offer?

Ok so I tried

sudo apt-get install libgdk-pixbuf2.0-dev
sudo gdk-pixbuf-query-loaders --update-cache

Came up with Reading package lists...done
Building dependency tree
Reading state information...Done

E: Unable to locate package gdk-pixbuf-query-loaders--update-cache

):
Is there anything else I can try?

Yes, I'd switch over to a console and run apt-get update and apt-get upgrade by hand. If it finishes successfully you are all good. If it recommends running dpkg with some options, do it.

You might also try apt-get clean. There might be stuff in the apt-get cache that's confusing the package manager.

From the man page:

Okay, my laptop is up and running again! Turns out I had to apt-get clean before doing anything else! Thanks for your help everyone! (:

(Grin) I thought of apt-get clean because I had a similar problem on my Debian box about two weeks ago and found the answer in a web search.

Glad you are running.
