Hi,

Is there anybody had experienced overheating after upgrade to Ubuntu 22.04..?

I upgraded my Asus ROG GL553VD from Ubuntu 20.04 to 22.04, and since then I've been experiencing overheating as if the CPU (or GPU) were at 100%, but top says the CPU is between 94-96% idle..

I even tried getting my CPU speed slower (using cpupower-gui), and setted it at 1.4Ghz, and being at 95% idle, it was still very hot and the fan at maximum speed..

How can I check what's going on with my system?

It never happened before.. I used 18.04, then 20.04; and never experienced this issue with those versions..

I'm attaching the current temperature in my system, which is extremely high..

Thanks for any help you can give me..

Well, I think that I've found the problem..

I found that Nvidia X Server Configurator showed the GPU in "performance mode", and Intel (the power savings option), is showed as disabled.. Maybe after upgrade the driver took the performance option as default..

I just selected the Intel option via command line using:
$ sudo prime-select intel
I restarted the machine and now seems to be OK, normal idle temperature has dropped a little, although I still see it high; as well as the fan speed.

Hope this can help anybody else..
