I first installed Ubuntu on my system in the year 2006-2007, when Canonical was distributing free copies of their Ubuntu Operating System disks, but I felt Windows was more user friendly when compared to Ubuntu. So I reformatted my computer and installed Windows XP.
Since past few years I have been using Cent OS, Ubuntu OS in AWS EC2 machines. I installed Ubuntu along with official Nvidia drivers in my Dell XPS 15 laptop which has NVDIA graphics card. Unfortunately, the official Nvidia drivers have a lot of problems with Linux distros, in general, which I didn't knew at that time. My system kept producing a lot of noise, heat, and it was very slow. I used it for few weeks, formatted and installed CentOS with official Nvidia drivers. CentOS was little better in terms of noise but heat production was similar to Ubuntu. Whenever my laptop heats up, it used to turn off without any notice. I tried using CentOS for few weeks and then migrated my OS back to Windows 7 again.
In May, I decided to give it another try. Before installing Ubuntu, I explored few forum threads related to Ubuntu installation on Dell machines and found that instead of official Nvidia drivers, we have to install bumblebee drivers.
The system works fine. Infact, the noise and heat production with Ubuntu OS is far lower when compared to Windows 7.
Update 2: Installed system upgrades which installed nvidia official drivers, started getting blank screen and couldn't login anymore. Then tried Elementary OS, same problem again, installed system upgrades, result - blank screen. After reading reviews about Linux Mint, started using it.
