I have Dell laptop and one week ago I replaced Windows 10 with Ubuntu 14.04 LTS. Ubuntu is working slow on my system i.e. in booting, shutdown, opening any application. My system specifications are:
- 8 GB RAM
- 1 TB HDD
- 2 GB Graphic Card (Nvidia-Geforce)
In windows, I had played lots of higher graphics games and it had been supported by system; but in Ubuntu, a Chromium browser taking time to load.
