I have a CPU with Nvidia GeForce GT 730. I did a fresh install of Ubuntu 18.04, alongside Windows 10. On Ubuntu, the GPU card fan is extremely high, although the temperature is fine, and this is not happening on Windows. Turns out the problem was the kernel’s stock Nvidia driver: nouveau caused the problem.
How to disable Nouveau Nvidia driver:
$ sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf" $ sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
Confirm the content of the new modprobe config file:
$ cat /etc/modprobe.d/blacklist-nvidia-nouveau.conf blacklist nouveau options nouveau modeset=
Then install the Nvidia drivers on Ubuntu 18.04 Bionic Beaver Linux using standard Ubuntu Repository. First, detect the model of your Nvidia graphic card and the recommended driver. To do so execute:
$ ubuntu-drivers devices == /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 == modalias : pci:v000010DEd00000F02sv00001462sd00008A9Fbc03sc00i00 vendor : NVIDIA Corporation model : GF108 [GeForce GT 730] driver : nvidia-340 - distro non-free driver : nvidia-driver-390 - distro non-free recommended driver : xserver-xorg-video-nouveau - distro free builtin
If you agree with the recommendation feel free to use the ubuntu-drivers command again to install all recommended drivers:
$ sudo ubuntu-drivers autoinstall
Or alternatively, install the desired driver selectively using the apt command. For example:
$ sudo apt install nvidia-340
Once the installation is concluded, reboot your system, and you are done.
