System constantly lagging

[ntertainer]

Hello,

I've been using Ubuntu for a couple of weeks and everytime i move the mouse, change window (or basically anything) for the first few seconds of doing it, the system stutters/lags.
Before Ubuntu, I used Linux Mint for a few months. I changed to Ubuntu because the same issue started there. With Ubuntu it has been from the start, so I'm guessing it's not just with the OS.

On Windows 10, which is installed on a different (but same exact model), I don't have this issue.

As for the hardware I have a
GPU: 5700xt
CPU: 3700x
RAM: Corsair 32gb DDR4 3200MHz
SSD: Corsair Force MP510 480gb m.2

Do you have any ideas on what might be the problem?

Thank you!

Sorry, I don't know what a 3700x CPU is. Please run inxi -Fz and post that command + output inside code tags, so everything lines up here. CPUs usually have a brand with them. Is it ARM, AMD, Intel, Citix, Via? Same for the GPU. Is there a brand?

We cannot read your mind.

GPU: 5700xt

This needs new stuff. The kernel that's in 19.10 has been released for 18.04's hardware enablement stack, but you'd still need a newer Mesa. There are PPAs that will add newer Mesa to 18.04: which one you go for depends on how much newness you're comfortable with.

Sorry, I didn't think that far. CPU is as it states in below output AMD Ryzen 3700X and GPU is PowerColor AMD Radeon RX 5700 XT Red Dragon 8gb.

How do I go about to do this? As I'm quite new to Linux overall, I guess I'm as comfortable to any newness as I can get. Thanks!

So you've probably noticed that all your software packages when you install or update them get downloaded from somewhere on the Internet that the package manager knows about. PPAs are just another somewhere on the Internet that you can tell your package manager about, so it can get new packages or updates from there as well.

I don't use AMD graphics myself, but I understand that this PPA is popular with those that do. It tracks the most recent point release, rather than the absolute newest dev version that people could test with (there are other PPAs that would give you those dev versions).

You just run the command listed on that page to add the repository, and then update or install your software in the normal way.

There's another package called ppa-purge (I don't think it's installed by default) that will automatically remove a PPA repository and downgrade any packages you've installed from it to the versions from the normal repositories. That's useful to have should you run into any problems, or if the software from a PPA doesn't actually do what you were hoping it would.

With Linux, because the manufacturers tend not to work with anyone not running Windows, it is best to stay 6-12 months behind on any hardware. You are likely in the "bleeding edge." New isn't always better. Sometimes it just means "barely works" until the hardware support gets into a new release. There are ways to use the newest code, but that is seldom point-n-click, so some technical expertise with Unix/Linux drivers is needed.

Anyway, I have a Ryzen 2600 (not bleeding edge) and an nVidia 1030 GPU (not bleeding edge). There were newer CPUs and GPUs when I built the system, but staying behind 1 generation was a hard learned lesson.

BTW, the Intel NIC is a good one, but it is only connecting at 100 base-tx? Any idea why not GigE? It should be providing 920Mbps throughput, easily.

Unless there is a kernel issue with that CPU, I'd look at the GPU drivers and swap setup for any stuttering issues. For a Linux desktop, 4.1G is the correct size for swap regardless of RAM, IMHO. There have been issues with systems not having enough swap showing really poor performance - something in the kernel wants _some_ swap. On a system like yours, swap is there to provide feedback when you've over extended the available RAM, so the user will "feel" the system get slower and take action to close some bloated applications. Running out of RAM (including swap) will crash a computer.

Thank you CatKiller. I added the PPA and made sure everything is updated/upgraded, but the issue still remains.

Might have to wait a while before everything starts running smoothly on my machine then, I guess.

When it comes to the NIC, unless the 920Mbps is shown otherwise, I'm guessing it's my network speed that limits it? Or am I completely lost in the woods?
As I'm guessing you've noticed, I'm not used to the more technical stuff.

I'll look into the swap setup to see if it would help.

Thanks!

Thank you CatKiller. I added the PPA and made sure everything is updated/upgraded, but the issue still remains.

That's a shame. You can try standard troubleshooting stuff, then; running something like top to see if some process is doing something weird at the point where you experience symptoms, checking logs, that sort of thing.

I also notice that there's a UEFI update for your motherboard that claims to

Improve PCIe device compatibility
Improve memory compatibility

Might help; shouldn't hurt.
