I installed Ubuntu on relatively good spec machine:
- I7-3770k,
- 32GB RAM,
- AMD HD7870 (2GB GDDR5),
- OS installed on 128GB corsair SSD.
Unfortunately, I was seeing very slow response. Mouse pointer just moves as I am using a 15 years old machine.
I used additional driver installation using in-built additional driver tool. Still performance is too slow. Here are few other detail from my console. Can some tell me as how to fix it... Thanks.
