The Problem
I have recently gotten a new development computer through work and have installed Manjaro on it, but from since day 1 the screen output has been super laggy. Honestly, I’m not even sure if it is the display, or the operations themselves, I can’t really tell and to be honest don’t know how to tell. The lag increases and decreases with CPU usage, even minimal it seems, like just switching between programs. When I’m in my IDE, it’s just lagging the whole time.
I have the computer plugged two Samsung 27" monitors. The thing is, I had this same monitor set up with a wayyyyy weaker laptop that I was using until it died which also had Manjaro on it, so I know the computer should be able to handle this lol.
Basically, I’m not sure how to proceed. I have checked dmesg
and journalctl
but I will admit that I am very ignorant on how to use these tools effectively; I always just scroll until I find suspicious things when I’ve had problems before, but nothing seems really off when I scrolled since getting this computer.
I would like to stress that this lagging does begin when I start having increased CPU work, or so it seems. I’m just suspect that it’s a CPU problem given that I have 20 cores and haven’t been doing much more than normal/heavy IDE stuff.
What I’ve Tried
Not much, I honestly out of my area of expertise here. I checked that the nvidia drivers were indeed installed, and tried switching from open to proprietary. I’ve tried to downgrade my kernel, but it seems that Manjaro has removed this ability from the settings menu, for idk what reason.
