How can I install the "third party" software option after I've skipped it in the installer? [duplicate]
Solution 1:
Open a terminal on the Dash and type:
sudo apt-get install ubuntu-restricted-extras
Enter your password and all third-party programs that you need to be installed. With this packages you will get also some extras like Microsoft fonts.
If you need proprietary drivers, go to System Settings -> Software & Updates and choose the hive "Additional drivers".
