HP Pavilion dv8 Intermittently freezes on Ubuntu MATE 19.1

Hello everyone, I have just joined the ubuntu-mate community, been Windows free for over 1 month now :smiley:

I have Ubuntu Mate 19.10 64-bit installed on an HP Pavision dv8 laptop. At first, it was really refreshing where I could focus on the work I needed to do rather than wait for the relevant application to start. It was really great for example that when I clicked on videos sent via Whatsapp Desktop (WhatsDesk), the videos played instantly! However I realize that after some time, trying to play a video resulted in the system freezing up, especially when another application was running in the background. I also attempted to Now, I can't even put a finger on what is causing the intermittent slowdown and lockup.

Here is my system info as obtained from inxi -Fx:

Just a shot in the dark here, but when my Linux systems lock up(assuming they are otherwise healthy,) it's almost always caused by using up all of my memory without realizing it.

You only nominally have 4G of ram, and there isn't a whole lot of it left these days after a couple of hours with a typical web browser open + 1 or two other tasks running in my experience. Try using a memory monitor to see if you're close to running out of free ram around the time when your system locks up.

If you only sometimes run out of ram you might be able to get by with setting up a swap partition if you don't have one already. Of course upgrading your ram(if possible) is the only real solution if this is your problem.
