My Ubuntu installation is so laggy and unresponsive. Firefox takes 10 seconds to start. Thunderbird takes 20 seconds or more.
I frequently have to hard restart.
I'm about to stop using Ubuntu if I can't improve performance.
I have an Asus X555 laptop and it has run beautifully for years. It has an i3-5010u CPU with Mesa Intel HD graphics 5500 (Broadwell GT2)
I use X11 windowing and GNOME 3.36.8.
