From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux way way slower than Windows? (lemmy.ca)

So I jumped ship from Windows to Kubuntu last night, and It's mostly been pretty good. However my general performance of the computer has been abysmal. Like it takes upwards of 5 seconds to open anything. All of my hardware seems to be running at max speeds, so I have no idea why it would be so sluggish? It's as if I'm running on 2gb of ram and a cpu at like 1.5ghz. My specs are:

i7-8700k at 4.7ghz max Amd Rx 6750xt 16gb ram at 3200mhz Linux is on an m.2

Any ideas? This is practically unusable for any normal operations, let alone any gaming.

Update: So it seems like my CPU is being throttled to it's min of 800mhz because the temp is just below 100c. Not sure why it's so high because I never got that high even in intensive gaming on Windows

Based on your update, are the AMD drivers loaded and working? Maybe it's using CPU for rendering instead of GPU.

Is there a way I can tell? I haven't downloaded anything manually as my monitors seem to work out of the box unlike windows

I haven't used Linux on desktop in ages but back in the.day we would do something like run gears to see if the animation was smooth and check the frame rate. Maybe use lsmod to check for the GPU's kernel module.

Install "nvtop" to see all GPUs Performance graph. I do not remember if Intel was supported for Performance graph, but at least you can see a change for your AMD GPU.

There are AMD Top tools to see all data from AMD too.

I don't think it would be throttled to 800Mhz if this was the case, though. It definitely sounds like their cpu cooler isn't working right. Maybe due to a kernel bug somehow, or maybe it just coincidentally died right when they moved to Linux.

yeah cpu fan/cooler does sound more likely.
