Description n1ghtf4l1 2022-11-03 14:21:13 UTC
SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Update System on 3rd November UTC +05:30 using sudo pacman -Syuu command. 2. Open Plasma Widget to display dedicated GPU Information. OBSERVED RESULT Dedicated NVIDIA GPU Usage, Temperature, Frequency, Memory Frequency values are not shown in either plasma widgets or Plasma System Monitor Application. Earlier there were 2 options when adding GPU Monitor widgets i.e All GPUs and GPU 1. After I updated the system using: sudo pacman -Syyuu The options changed to All GPUs and GPU 2, where GPU would stand for showing dedicated NVIDIA GPU information but now it doesn't show any information related to dedicated NVIDIA GPU. I have checked NVIDIA X Server is working properly and showing all columns with correct values. EXPECTED RESULT Dedicated NVIDIA GPU Usage, Temperature, Frequency, Memory Frequency values should should be visible in real time in plasma widgets as well as Plasma System Monitor Application. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro Linux x86_64/ Plasma 5.26.2 (available in About System) Kernel: 6.0.6-1-MANJARO KDE Plasma Version: 5.26.2 KDE Frameworks Version: 5.99.0 Qt Version: 5.15.6 ADDITIONAL INFORMATION

I am having the same issue; System Monitor is unable to display details about my NVIDIA dGPU (reports default stats; 0C, 0%, etc.), but my AMD iGPU reports just fine. (In my laptop, amd is 'GPU 1' and nvidia is 'GPU 2') nvidia-smi is functioning as intended. The 'GPU Name' sensor correctly reports my iGPU's name as 'Rembrandt [Radeon 680m', but incorrectly reports my dGPU as 'GPU 2' Hardware: Laptop: ASUS Flow X16 CPU: AMD Ryzen 7 6800HS with Radeon Graphics (16) @ 3.200GHz GPUs: AMD Rembrandt Radeon 680M, NVIDIA RTX 3060 Mobile / Max-Q Software: OS: Arch Linux x86_64 Kernel: 6.0.6-arch1-1 DE: Plasma 5.26.2 WM: Kwin Nvidia Driver: 520.56.06 Additional information: $ plasma-systemmonitor --version plasma-systemmonitor 5.26.2 As of writing this post, all installed packages are up-to-date. If any other datapoints are required to pinpoint this issue, let me know, I'd be happy to provide more info.

(In reply to Nate Graham from comment #2) > > *** This bug has been marked as a duplicate of bug 461389 *** In bug 461389 gpu name for dedicated nvidia gpu changed from gpu 0 to 1 but in my case as well as @saik's case it changed from gpu 1 to 2. As a result default values are shown i.e 0%, 0 degree C etc. I believe there is some error in the update which mistakenly changed gpu name from 1 to 2 as a result of which system can't find gpu 2 hence displaying default values. If somehow we can change gpu name of our dedicated nvidia gpu from gpu2 to gpu1, i think problem will be solved. In bug 461389, NVIDIA gpu was set as primary gpu, but in my case intel gpu is set as primary gpu. Even though expected result is same, conditions are different.

Even though expected result is same, conditions are > different. Before I updated the system, I've also set Intel as primary GPU. I think it has caused the name change of Nvidia GPU.

I think we're talking about the same thing. In the widget settings and in System Monitor, the GPU name has changed from "GPU 1" to "GPU 2" for me as well. But if you look for example in `~/.config/plasma-org.kde.plasma.desktop-appletsrc`, you'll probably find the paths to GPU sensors like `gpu/gpu1/usage`. So for "GPU 2" in the widget settings, the config name is "gpu1".

this issue seems to be back with latest nvidia driver 535.54.03
