I'm running Kubuntu 20.04 on a laptop with an Intel i7-4700mq and a Nvidia GTX 770m.
After the fresh installation , everything worked with the Nouveau driver.
After installing the proprietary drivers Nvidia 390(recommended) the CPU started to overheat. While using nouveau driver the idle temeperature would be 47 , but with nvidia 390 driver idle temperature is around 61.
I tried to switch to Intel via nvidia-settings prime profiles , and via prime-select
, but it doesn't work.
The result of ps auxc | grep -i therm
root 181 0.0 0.0 0 0 ? I< 18:15 0:00 acpi_thermal_pm
root 963 0.0 0.0 125860 9964 ? Ssl 18:15 0:00 thermald

ps auxc | grep -i therm
. And, if you have lm-sensors installed, if not, install it, and show mesensors
.sudo apt-get purge thermald
. Also, Nvidia 418.88 can be downloaded from geforce.com/drivers. How old is this laptop? Is it very dusty/dirty?
