Temperature and other statistics from Radeon Open Source Drivers?
Try the usual approach:
- install the package
lm-sensors - run
sudo sensors-detect, answer all the questions - run
sensorsto see readings
For a GUI, you can use sensors-unity from Snapcraft.
You can also use radeontop to get live statistics on your graphic card. It only works with r600 and newer.
sudo apt-get install radeontop
