I have a DELL Insipron 15 7000 2-in-1. I've been running manjaro and KDE for quite a while for my development machine.
Typically I have the following open:
-visual code working on web or react-native apps
-a few terminals
-google chrome with a maybe 6 tabs, debugging web pages
Previously, doing this has been working wonderfully fine.
I recently did a big update to a new kernel and a huge update to manjaro/arch.
Since then, my laptop has become a laggy unresponsive mess.
I tried formatting and that helped a little, but its gotten so bad I've had to remove the Android emulator and revert to using my phone which is tedious. Even then it has made little improvement.
I am wondering how I can isolate what the problem is?
I have tried leaving the KDE system monitor running, and CPU usage might sit arounf 50% with the odd spike to 80%. Memoy sits around 5gb usage of 8gb ram (plus I have 16gb of swap)
Network usage barely registers.
So everything looks fine there. How can I isolate the problem to resolve this unresponsiveness?
Today I've just downgraded kernel to see if that helps, i'll run that for a few days and see if there is any change.
