long time Windows user here. Recently I've made the switch to Linux (Ubuntu) and I've spent the past couple of weeks learning the ins and outs of the OS and customizing it to my liking. It was awesome for a few days, everything was snappy and applications were loading quicker than on my Windows OS, which I expected.
Now all of a sudden my Ubuntu OS is running slow (I am dual-booting Windows and Ubuntu) It's taking at least 4-5 seconds to load some applications, particularly Firefox and CLion two applications I use religiously on a daily basis. Another problem is; running commands on the Terminal now takes 2-3 seconds to load the application or function of the command.
I thought maybe it might be some the themes I've installed so I did some troubleshooting and I removed all themes and set my Ubuntu back to default to see if that makes any difference, and nope still running slow.
