Hi qon,
I have been looking at your Github repository: https://github.com/davidrohr/clevo-indicator, would you mind updating it with your latest changes? I have look through all the forks and your changes are the only one that work for my Clevo laptop except the GPU temperature but I believe you have a work around by using the nvidia-smi utility.
BTW, if you are looking for keyboard light control for your Clevo laptop, have a look at https://bitbucket.org/lynthium/clevo-xsm-wmi.git , it is working for me.
Thank you.
