1. To solve problem of Skype not working in Ubuntu 13.04 Raring Ringtail with proprietary Nvidia or AMD graphics drivers, let us first rename the Skype executable from "skype" to "skype-bin". Do run this line in your Terminal:
sudo mv /usr/bin/skype /usr/bin/skype-bin
2. In second step, Let us create a file called "skype" under the directory /usr/bin/ . We can use Gedit to create a file nammed skype in the mentioned directory as follows(Note that you need to be the root):
gksu gksu gedit /usr/bin/skype
In this file, copy and paste the following code:
#!/bin/sh
export LD_PRELOAD=/usr/lib/i386-linux-gnu/mesa/libGL.so.1
exec skype-bin "$@"
Now save the file.
3. And in the final step, run the following command in a terminal:
sudo chmod 0755 /usr/bin/skype
You are done. Now your Skype should work in Ubuntu 13.04 Raring Ringtail properly. See it Yourself.
If you want to revert the changes made by using the instructions above, run the following commands in your Terminal:
sudo rm /usr/bin/skype
sudo mv /usr/bin/skype-bin /usr/bin/skype
Enjoy the power of Ubuntu.
