Ubuntu Support Template
Ubuntu Version:
25.10
Desktop Environment (if applicable):
KDE Plasma (Kubuntu)
Problem Description:
I am trying to get Psensor to show my GPU temp, but I can’t get the GPU sensor to show up in the program.
Relevant System Information:
Nvidia RTX 4080 Super
What I’ve Tried:
I have installed Nvidia open kernel 580 driver using Driver Manager in settings.
I installed lm-sensor (apt-get)
I installed Psensor (KDE Discover)
At this point, CPU info, NVME info, and RAM info showed up.
I read online steps to ensure that sensors are detected, and ran:
‘sudo sensors-detect’
The only output was:
To load everything that is needed, add this to /etc/modules:
#----cut here----
Chip drivers
coretemp
#----cut here----
I tried Psensor again, and no GPU sensor still.
I read more and saw that I should test to see that nvidia driver works and ran:
nvidia-smi

I can see fan settings in nvidia app, and can hear the fans kicking on in games that seem to run as well as they did in Windows (just switched), but no sensor.
I am at the end of what I can find with searching online, and thought I would come here as I am just returning to Ubuntu after a huge hiatus from Linux.
I would like any advice on things I can do to get the sensor(s) to be detected. Thank you in advance.
