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

I would start by checking for any sort of errors in your system logs, such as
/var/log/syslogor usingdmesg -w. In my experience, Linux is almost universally faster than Windows.When I switched from Windows to Linux I found cockpit-project.org to be a true blessing when troubleshooting. Something about having logs and services in a Web GUI that can be really helpful.

Yeah, there’s probably something wrong. This is good advice. Maybe some tool can also do a performance benchmark to find the culprit. I’ve seen a lot of Linux computers. And except for some strange hardware, it’s supposed to be (at least) as fast as anything else.
Except for GNOME cause the DE is essentially a browser engine and CSS themes :)
no, you are wrong about it being slower, and also about it being a browser
Yeah sure, keep working in your delusions.
GNOME Shell is tightly integrated with Mutter, a compositing window manager and Wayland compositor. It is based upon Clutter to provide visual effects and hardware acceleration.[20] According to GNOME Shell maintainer[21] Owen Taylor, it is set up as a Mutter plugin largely written in JavaScript[22] and uses GUI widgets provided by GTK+ version 3.
https://en.wikipedia.org/wiki/GNOME_Shell
And yes, GNOME is slower than Windows, KDE and Xfce. Always has been, always will be. It might be polished but it is slow.
where is written that gnome is a browser?, they only use javascript, like they could have used anything else, still don’t make it a browser, or like one
and yes it’s lighter than windows, proved by ubuntu being recomended for lightweight OS(even when they use extensions and Snap), and where i said that it’s lighter than KDE and Xfce for you to bring it up lol
By definition something that executes JS and parses CSS is a browser.
and yes it’s lighter than windows, proved by ubuntu being recomended for lightweight OS
Absolutely not. It gets recommended as a lightweight OS because 1) there are delusional people and 2) if you remove and stop everything on Windows 10 that you don’t it will be faster, way faster than anything running GNOME.
The problem isn’t the OS per si, the problem is the UI. GNOME is SLOW as hell and even if the OS behind it is way more efficient than Windows it will lose against a debloated Windows 10 setup because Window’s UI is fully native and way faster.
I agree GNOME is resource heavy however that has nothing to do with Javascript being involved. The James Web Telescope uses Javascript for some of its core functionality (specifically managing its science modules), does that make it a web browser? I personally don’t like GNOME either, but most of it is written in C, it has its own GUI library which is written in C. The Javascript code likely just is used to simplify calling the underlying C functions and CSS is used for customizing the actual UI elements.
By definition something that executes JS and parses CSS is a browser.
This is wrong. A browser parse a html document and construct a DOM, executing JavaScript and CSS are optional. GTK apps don’t have DOM, GTK has ability to parse UI styles from css instead of from XML so styling can be separated from UI definitions. Modern UI toolkits like QT (used extensively by KDE) also have CSS supports.
Which distribution of Windows would you recommend for this debloated experience?
I guess excel is also “just a browser” since it can run JS too?
Excel is everything, runs on a Browser, can run a Browser and everything in between :D
isn’t that basically what the windows ui is, too?
Absolutely not.
Windows 11’s shell is mostly WebView2.
And you say that because…?
…it’s true?
No it isn’t.
Since you mentioned high cpu temps, do you have a water cooler? It’s possible that the pump is running at a reduced speed or not at all. If it was functioning fine on windows that leads me to believe that it’s not hardware related like some are suggesting.
I do have a AIO radiator. The pump itself is plugged into CHA_FAN1 and shows about 1600RPM, but I don’t remember the normal speeds
Are your AIO fans, pump, etc. connected to the motherboard or through a USB hub?
OP this comment could be a major clue to whats happening with your AIO.
I have some fans connected via hub, but the pump and aio fan are connexted directly to the motherboard
That would be where I’d look first. A lot of AIO manufacturers only write drivers for Windows. There’s an old Reddit thread that has a few things to try. If this is your first dip into Linux get used to googling things. A lot of things. Ubuntu or Kebuntu are great OS to start on because there is always a forum post or a Reddit thread that deals with exactly what you’re dealing with. Once you are more comfortable I’d move onto Linux Mint or straight Debian. All those nice things that make Ubuntu easy to learn will eventually also hold you back.
If your AIO pump came with a hub you likely need to use it instead of plugging directly into the Mobo.
As an example my corsair AIO came with a hub and i didnt want to use it. Finished my build and found out i absolutely had to use it in order for the device to work properly.
Check your motherboards manual, there may be a water cooling pump specific header.
AIOs typically pretend to be a fan and you would only need to use that with a custom loop.
I’ve had a few issues with fan control on AMD hardware. In your motherboards BIOS, try taking all fan control off auto, and set it for full load. In your OS, download Radeon-Control (AMD GPU Fan control) and set it for full load. See if your Temps stay high. I think Kubuntu comes with Fan-GUI (I think that’s what it’s called). Disable it.
With temps that high in Linux and Windows, it almost sounds like the AIO water block is falling off the CPU.
or the pump has failed
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.
What i would figure out first is why tf your hardware runs on max all the time.(Maybe a bugged out program?) You can do so via top/htop/btop etc.
Generally I would say the exact opposite is the norm. Every Linux flavor I have tried feels a lot faster than any of its peer windows versions
For me, Garuda Linux with Gnome or KDE felt very laggy. But this experience is old.
But a lot of distros do feel much smoother than Windows for me too.
Are you using snaps? Snaps are notorious for God awful performance.
Any Ubuntu affiliated distro is required to use snaps, so Kubuntu will use them. Startup times are terrible, but running performance should be the same.
Another simple distro to try would be either Mint or Pop-OS. Both are still Ubuntu based, but without snaps
Mint’s interface (Cinnamon) is similar to Windows, Pop-OS uses a modified GNome
Do you use some weird cooling solutions? Drivers may be an issue. The other possibilities I can think of are hardware related.
if your CPU is at 100%, running “top” will show you what’s taking CPU time
htop is another good option. And for OP if they aren’t familiar, it’s control-c to exit these little terminal apps.
My current favorite is
btop. Very nice TUI.Wow, that is nice.
I think pressing Q works too to exit htop.
I’m not sure about how much up to date Kubuntu’s drivers are but maybe, if the software is at fault, changing to a more bleeding edge distro, like Fedora KDE, would solve this issue with temperature.
The thing I experienced on my laptop was: I used on Linux Max Performance while on windows I let it be the default (balanced or smth I think). The result: my Laptop hit way too often 100°C when playing games that my CPU throttled to 800mhz. It was a quick fix by just using balanced instead so it can decide for itself when to cool a tiny bit to not throttle, like windows.
There are multiple tools to set the Intel Power Management Profile to “Balanced” instead of “Performance”
This sounds like a hardware problem. Keep in mind that thermal paste doesn’t last forever. I’d rebuild it.
When you know it’s overheating, you could as well try and remove dust, with some compressed air. It can’t hurt.
Sure, but it’s not like the dust suddenly appeared when switching to linux, this is a software/driver issue.
Did you change some hardware when you switched? Put a new SSD in? Maybe you knocked something for cooling lose. Or blocked some vent.
Do you have the Windows installation still? You could try to see if it’s showing the same symptoms. Or download some other Linux and boot that from USB.
So windows also gives me a reading of just under 100C but has no problem running my cpu at 2ghz or higher. So I’ll have to take a look at my radiator and see what’s up.
I installed a SATA ssd to boot windows to because I need it for university, but didn’t mess with cooling. Thanks for the help
Your cooler isn’t working, or poor contact with the CPU maybe.
With an AIO you should not be seeing more than 60-70C on most setups.
Does windows give you just under 100C when you’re just browsing the web or watching videos??
If so then your thermal set up is not working properly. You should check to make sure you’ve got thermal paste on your CPU and the cooler is mounted properly and making good contact. Also some people may accidentally leave the clear plastic sticker on the cooler where it makes contact with the CPU.
I’ve never water cooled so I can’t give advice there.
The 8700k is rated for a max temperature of 100C so it shouldn’t really be anywhere near that at idle. https://ark.intel.com/content/www/us/en/ark/products/126684/intel-core-i7-8700k-processor-12m-cache-up-to-4-70-ghz.html
For context my 7900x is at about 40C at idle and I don’t think I’ve seen it go over 75C under load.
CPUs thermal throttle as they reach their maximum rated tempuratures which would explain why everything is running slower.
Linux may have different thermal cutoffs for when to throttle compared to Windows, so that might explain it.
I’d reseat the connector for the water pump. I just installed a new PSU last week and when I turned it on, I had no RGB. I didn’t even think I went near the RGB header, but I ended up having to reseat it.Can you try changing the power profile to “balanced” or “performance” in gnome/kde settings? Or is it stuck to “power save”?
I’m unable to change it, I think because it’s a desktop, not a laptop
Those should work on desktop as well. What’s the result of running this command:
sudo systemctl status power-profiles-daemon
I agree it sounds like your cooler is failing or not installed correctly.
