Re: gpu core temp readout problem

Bill or whoever is now doing the code -


i found out what the problem is.. .nvidia changed the syntax on reading coretemps.. here 
is the info

------------------------------------
You'll need to query the thermal sensors directly:

nvidia-settings -q [thermalsensor:0]/ThermalSensorReading

Each card has two thermal sensors, core and ambient, so thermal sensors 0,2,4 will be the 
core temperatures and 1,3,5 will be the ambient temperatures.

---------------------------------------



when using that i get the proper information manually:

odyssey etc # nvidia-settings -q [thermalsensor:0]/ThermalSensorReading
Xlib:  extension "RANDR" missing on display ":0".

  Attribute 'ThermalSensorReading' (odyssey:0[thermalsensor:0]): 64.
    The valid values for 'ThermalSensorReading' are in the range 0 - 191 (inclusive).
    'ThermalSensorReading' is a read-only attribute.
    'ThermalSensorReading' can use the following target types: Thermal Sensor.

odyssey etc # nvidia-settings -q [thermalsensor:2]/ThermalSensorReading
Xlib:  extension "RANDR" missing on display ":0".

  Attribute 'ThermalSensorReading' (odyssey:0[thermalsensor:2]): 55.
    The valid values for 'ThermalSensorReading' are in the range 0 - 191 (inclusive).
    'ThermalSensorReading' is a read-only attribute.
    'ThermalSensorReading' can use the following target types: Thermal Sensor.

odyssey etc # nvidia-settings -q [thermalsensor:4]/ThermalSensorReading
Xlib:  extension "RANDR" missing on display ":0".

  Attribute 'ThermalSensorReading' (odyssey:0[thermalsensor:4]): 58.
    The valid values for 'ThermalSensorReading' are in the range 0 - 191 (inclusive).
    'ThermalSensorReading' is a read-only attribute.


on the dual circuit board gtx295 thermalsensors 3 and 5 will report each board's ambient 
temp.  on the single board version they both report the same.


i do not know if this is compatible with older versions of nvidia drivers or not. if you 
feel you should not make this change, at least now, i can find the code and do it for my 
own special version.

or is this variable in some configuration file that i can change?
