I recently installed Ubuntu 18.04. Before I had Linux Mint and everything has been nicely working. Whet I just installed 18.04 one, it was working pretty slowly, then it started working better little bit but still not enough. When I click on "Show Applications" button at the left bottom corner it works extreme slowly. I have good hardware, I don't know why it works so. Maybe due to drivers? If so, how can I update all of them up to date (with terminal please)? I think it's due to problem about GPU or CPU drivers. When I had Mint it was working the same, but started working really good after installing CPU and GPU drivers.
8 GB RAM, Nvidia GTP 1050TI, I3 6100. I don't know what drivers, I just use standard Ubuntu "Software & Updates" for this.
