SUMMARY *** Utilization, VRAM, temperature, etc. worked with my Nvidia gpu before, but since a recent driver update (I'm now on 525.60.11, but it broke 2 or 3 updates before) it's no longer working. It still detects my Nvidia gpu (GPU1), but it shows 0% utilization, 0°C temperature, 0 MB VRAM, etc. The desktop applet ("system monitor") is affected, too (same behavior there). Nvidia X Server Settings and the nvidia-smi still show the utilization, vram usage, temperature, etc. correctly. Other applications (like Unigine Valley benchmark) still show the correct values. *** STEPS TO REPRODUCE 1. Update nvidia driver 2. try to show utilization/vram/temperature with Systemmonitor application or desktop applet OBSERVED RESULT Shows 0%, 0°C, 0MB, etc. EXPECTED RESULT Shows the real values (e.g. 90%, 71°C, 2000MB) SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed (available in About System) KDE Plasma Version: 5.26.4 KDE Frameworks Version: 5.100.0 Qt Version: 5.15.7 ADDITIONAL INFORMATION Tested with multiple gpus (GTX 1080, RTX 3070)
