I have installed Ubuntu 12.04 LTS version on my Inspiron 1520 (Clean installation). Some of the drivers are not working properly and some features are not available as well. Ex: WiFi networks are not detecting and WiFi locator switch on the left is not working.
I like to know how to install all the drivers for Ubuntu 12.04 (any available instructions), and configure the OS properly to work with Inspiron 1520.
First Step I would advise is to find the correct hardware details and find its corresponding drivers. you can try to list pci devices linux and search its corresponding drivers.
