I'm using Dell inspiron 5420 (14R 3rd generation), and tried to install Ubuntu 10.10, 11.10, 12.04, 12.04.1 but each and every time, it doesn't support any of my driver such as network card, wireless driver, video driver and as well as audio and touch-pad driver. audio, video and touch-pad works with their basic functionality but don't work with their full functionality.
I'm a new user of Ubuntu, and willing to use it permanently. In this condition I tried some solutions from the web but didn't get out from this problem.
For this I'm knocking to you, if you give me the proper solution for getting out of this problem, I'll be very grateful to you all.
