Hey All,
I’m very new to using KDE Plasma DE on my system. Prior to that, I’ve been a long-time Gnome user.
What I’m observing is that, while Plasma overall is actually better on memory use than Gnome for me, CPU use is much higher. The main culprit seems to be kde_wayland. And this is the driver of some pretty high CPU temperatures, sometimes as high as the low 90s C. I’ve never seen temps that high prior to this. And that is with load avgs below 1.
All of the apps that I run are configured to run under Wayland, if that would make any difference. The only app I regularly use that’s not is 1Password.
Am I the only one who’s experiencing this?
I didn’t use wayland too much, but I’ve never had such high temperatures on my CPU while using it. 90 degrees Celsius is way too much, you should access the BIOS and define your own curve for the CPU fan, see if this solve the issue.
Yeah, that high temp was a shocker. All of this is observed from a fairly basic laptop, a four year old Lenovo Yoga 6, with an AMD cpu/igpu (AMD Ryzen 5 PRO 4650U with Radeon Graphics (12) @ 2.100GHz).
I was using it on a lap desk, so didn’t feel how much heat it was generating. I did observe how quickly it was draining cpu, though, so ran btop to see what was driving that. The number one process? kwin_wayland, by far. But I’ve seen that a fair bit after regularly checking it over the past couple of weeks, so I was still pretty surprised .
Keep in mind, though, this isn’t a “clean install” of a KDE-specific spin, so this situation could be unfair. Other things could be acting counter one another and driving the cpu use higher. I was really just wondering if others had experienced something similar.
