Dear Maintainer,

In Fedora 43 Kde Plasma the system monitor GPU pie chart works perfectly however on Debian it always
showing 0.

Thanks for the help!

Hi,

I have it working on multiple systems with AMD graphics. So there must be something more specific to your issue.

Can you find anything when running it from a terminal ?


Thanks,

Hi Aurélien,

I apologize for not providing the system info / specs. Here is my laptop info:

Operating System: Debian GNU/Linux 13
KDE Plasma Version: 6.5.1
KDE Frameworks Version: 6.18.0
Qt Version: 6.9.2
Kernel Version: 6.17.6+deb14-amd64 (64-bit)
Graphics Platform: Wayland
Processors: 16 × Intel® Core™ Ultra 7 255H
Memory: 32 GB of RAM (30.7 GB usable)
Graphics Processor: Intel® Graphics - Arc 140T
Manufacturer: ASUSTeK COMPUTER INC.
Product Name: ASUS Zenbook 14 UX3405CA_UX3405CA
System Version: 1.0

I should be more precise about my problem. The gpu monitoring is working on the Application / Process panel in the System Monitor with text only, however the only issue I'm having is the Pie Chart / Graph in the system monitor which always showing 0, I configured the sensor using the same working one on the Applicaiton panel but it still showing 0% on the Pie Chart. This isn't the issue on Fedora 43 that I've tested, I also tested on Ubuntu as well as KDE Neon the result are the same they all don't work all showing 0%, for now the only working distro I've tested is Fedora 43.

I've enclosed the screenshot of the system monitor hopefully it will explain the issue more clearly.

Thank you so much!
Best Regards,
David

Hi,

I can confirm the bug with my laptop with Intel graphics.

Intel Corporation TigerLake-LP GT2 [Iris Xe Graphics] (rev 01)

I run in terminal but do not see any interesting message :(

QT_LOGGING_RULES="*.*=true; qt.*=false" plasma-systemmonitor

(or do you know better categories I should enable?)

regards,

hefee

Hi,

I've posted this issue on Kde Discuss as well and one of the developer replied me saying that this could be distro releated and he shared a link he patched awhile ago and the ksystemstats_intel_helper is required for it to work and it requires a special privileges, may be this might help to narrow down the issue perhaps?

This is the Kde Discuss Thread;
https://discuss.kde.org/t/plasma-6-5-2-system-monitor-gpu-monitoring/41246/4

This is the link the developer shared:
https://mail.kde.org/pipermail/distributions/2025-April/001572.html

I've also tried the command line version (kstatsviewer) just to make sure it is not the system monitor issue the result is same everything related to gpu are showing 0.

As the Kde developer replied the reason I do have the value work on the application / process panel is because it is using different method of reading / showing the value.

Thank you so much,
David

Hi,

Could you try running :
    sudo setcap "CAP_PERFMON=+ep" "/usr/lib/x86_64-linux-gnu/libexec/ksystemstats_intel_helper"

and see if it indeed fixes the issue for you ?
If so I’ll ship the fix in the package.
(I don’t have such a system at hand otherwise I’d have tested myself.)


Thanks !

Hi,

I've already tested that line of command but sadly it still doesn't work. I tried to remove and add back the sensors after running it but still it is showing 0 on the graph panel.

David

Hi Aurélien,

It works turn out it's the "syntax" error and I set both CAP_SYS_ADMIN as well as CAP_PERFMON and reboot and now the pie chart showing the value correctly.

sudo setcap 'CAP_SYS_ADMIN=+ep' /usr/lib/x86_64-linux-gnu/libexec/ksystemstats_intel_helper

sudo setcap 'CAP_PERFMON=+ep' /usr/lib/x86_64-linux-gnu/libexec/ksystemstats_intel_helper

Thank you so much!
Best Regards,
David
