At the time I made a (unreleased) nvclock based gkrellm plugin. Will finish this plugin soon and will also write a gtk applet, so watch out for some cool stuff.

I sent a mail to Alex Murray (the maintainer of the GNOME Sensors applet) and asked if he was interested in adding support for nvidia cards. He said he will look into supporting it in the next release, so stay tuned!

PS: His nvidia card doesn't have a temperature chip, I suggest if anybody have something lying around they donate it to him, or just send him beers

If he adds it, you tell him I will personally purchase him a 24 pack.

Zander,
Is it possible to write an i2c module for the nVidia GPU? This way each /every/ sensor display software will be able to interact with nVidia cards.
If you can release a known driver interface to it, I'll be happy to contribute the time require to write a i2c module for it. (Though I doubt that you'll need my help )

Cheers,

But it isn't over the i2c bus :P

I doubt that it'll be a problem...
Non I2C bus devices were already ported to use the i2c interface in the past. You just need to write the right driver for it.

Various GeforceFX and earlier cards with hardware monitoring capabilities contain a sensor chip connected to the i2c bus. Generic Geforce 6800 class cards also use a sensor chip (LM99/MAX6659) or some vendors like Asus/Gigabyte add more advanced sensor (F75375S/W83L785R) which are unsupported by nvidia-settings. The case is different for other Geforce6 boards some use a i2c sensor but there also seems to be some builtin sensor. This seems to apply to Geforce 6200/6600 and 7800 boards. Note that the sensor isn't enabled on most 6200/6600 cards. Myself I added a i2c driver to nvclock (cvs) some time ago with support for all mentioned chips except for the builtin one. (don't have Geforce6 hardware) I hope to add low-level access support for it soon and also a way to enable the chip when it is disabled.

My GKrellM already shows GPU temperature - but it is *very* dumb.

1) It executes nvidia-settings
2) It executes it even if GPU temp. is not selected to be shown - and that is very bad because I cannot have GKrellM running while playing games (nvidia-settings always takes some CPU power at startup)

ksim (part of kde) has support for viewing nvidia's temps...

But, all these applications I've seen so far just fork out external binaries like nvidia-settings or nvclock to read the temp settings. While it does provide GPU temp readings, this is grossly inefficient. I would much rather prefer a single binary that has some timed looping using the NVIDIA APIs to query temperature.

Thunderbird,

From where does nvidia-settings collect the info? From the driver or from user-land tools?
I've got a Gigabyte 6800GT; lm_sensors doesn't detect anything on the i2c bus, but nvidia-setting does report a valid temperature reading.
