All right, so I recently fixed my Toshiba Satellite L75D-A7283 back up to use as a backup laptop. I have 8GB RAM and a 500GB HD.

I took the HD out of a Samsung laptop I was using (with Linux Mint 19.3 installed) and put it in the Toshiba. It appears that Linux Mint booted up and works fine with one little issue...

It seems every few seconds, it's like the system has a hiccup. This happens when I am typing on the keyboard, playing back video, etc. I first noticed when I would play back videos in my video editor (Openshot) and also confirmed it playing back a video in VLC too. And I've noticed these little stutters and hiccups as I am typing too (like this message for example). Not sure what happened as I didn't notice these issues when the HD was in the Samsung laptop and its hardware is pretty similar. But there must be something new here that is causing this.

I am almost wondering if it's a graphics issue.

Seeing as how this drive already has a previous install of Mint from another PC, I'm just going to start from the ground up and do a "fresh" install of Mint. hehe Minty "fresh". I wouldn't mind redoing the partitioning anyways. Then I'll just go from there if the issue is fixed or continues. If it still doesn't work then I will distro hop til I find something that works.

Most likely thing is that you've optimized the X driver for the other PC.Presumi9ng the video isn't identical, you'll have to set up for the new one.

You can open a terminal, run and try to trip your video up. Also read through your logs. SAee if you hit any errors.

Yeah I think that's what must have happened business_kid. Thanks for the info.

Did a fresh install of Linux Mint and all is well now.
