Fan Speed High
I have often found that the fan speed is high after I install a new version of Ubuntu, so this is what you do to fix it.
- 1) Install lm-sensors: sudo apt-get install lm-sensors 2) Run sensors-detect which will install the 'coretemp' module: 3) Run in terminal: more /etc/modules 4) Modify /etc/default/grub: sudo gedit /etc/default/grub.conf
Change from:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"
- 5) Update grub: sudo update-grub 6) Reboot your machine
