I want to use coolbits to increase fan speed of my Fermi GPU. 280.13 driver installed. Ubuntu 11.10
I edited /etc/X11/xorg.conf as follows, by pressing Alt+F2 and
gksu gedit /etc/X11/xorg.conf
Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTX 470" Option "NoLogo" "True" Option "Coolbits" "4" EndSection Started getting these messages, Gtk-WARNING **: Unable to locate theme engine in module_path: "pixmap"
So I did this,
sudo aptitude install gtk2-engines-pixbuf
a@z:~$ nvidia-settings -a [gpu:0]/GPUFanControlState=1 a@z:~$ nvidia-settings -q fans
1 Fan on z:0
 z:0[fan:0] (Fan 0)
a@z:~$ nvidia-settings -a [fan:0]/GPUCurrentFanSpeed=80
ERROR: Error assigning value 80 to attribute 'GPUCurrentFanSpeed' (z:0[fan:0]) as specified in assignment '[fan:0]/GPUCurrentFanSpeed=80' (Unknown Error).
So, it's not working; I can't enter the fan speed percentage. Also from NVidia X Server, there are no fan controls.
