nVidia fans, optical out off, bluetooth off
Turn off optical out
To find out the name of the optical device, check the output of amixer: amixer > test.txt (then open test.txt and look for IEC958-something). Turn off optical s/pdif IEC958: /usr/bin/amixer set 'IEC958' 'Playback' 'off' About optical out: http://www.mythtv.org/wiki/Setting_A_Button_On_Your_Remote_To _Toggle_The_S/PDIF_Audio_Source About bluetooth: http://catlingmindswipe.blogspot.se/2012/05/how-to-disable- bluetooth-on-startup.html nVidia GPU:s - Adjusting fan speed
Run this to install settings dialog; apt-get install nvidia-settings Check for xorg.conf file: dir /etc/X11/xorg.conf If the file does not exist, do the following: X :1 -configure mv xorg.conf.new /etc/X11/xorg.conf Open xorg.conf in an editor If you just created the file, remove all sections but the following considering the nVidia card: Section "Device" Identifier "Card1" Driver "nvidia" BusID "PCI:1:0:0" EndSection Then add a "Coolbits" line, this allows control of fan speed: Section "Device" Identifier "Card1" Driver "nvidia" BusID "PCI:1:0:0" Option "Coolbits" "4" EndSection Save the file. You may also try 5 as a value for coolbits if it does not work. You may now open nvidia-settings in Unity and change speed for the session. Do this to set fan speed without the dialog; /usr/bin/nvidia-settings -a [gpu:0]/GPUFanControlState=1 /usr/bin/nvidia-settings -a [fan:0]/GPUCurrentFanSpeed=55 If you want to make the changes permanent, make a script file and put the script file into the startup applications (in Unity).
