I bought a laptop with ubuntu and Nvidia geforce 820M 2GB graphics about 7 or 8 months back. Since then I've stuck with ubuntu and didnt install windows.
However, I havent installed my graphics driver for nvidia on this system and I'm using the stock one (Intel HD 4700) presumably. I tried installing the graphics driver a couple of months back but due to lack of proper experience ( I still dont know much) with ubuntu, I wasnt able to troubleshoot all sorts of problems which started occurring after installing the nvidia driver. Ultimately, I ended up restoring the factory settings a couple of times.
Recently, one of my colleagues advised me to install the graphics driver as he believed that if my GPU was left unused for quite a time, it would not function if at a later date I actually needed it.
Does any truth lies in his believing ?
Should I actually make efforts to install the graphics driver ?
I am asking this because last time I tried it took me nearly 3 or 4 days to ultimately fail in my attempt (Since I'm just a casual ubuntu user). Problems with touchpad to wifi and bluetooth started arising upon installation of the same, which had me freaked out. So another attempt can possibly break my already set and working system (I have installed a couple of important tools reqd for work).
