Hello there,

I'd like to ask how likely is it to have NVidia support on future versions of
sensors-applet.
I have tried to compile it myself starting from debianized sources and
adding the "--with-nvidia" flag to debian/rules, but compilation stopped
complaining about missing nvidia libraries (that should be provided with
package nvidia-settings, which I have installed).
So I downloaded the latest available nvidia-settings package from
nvidia.com, compiled libXNVCtrl myself, put the headers in
/usr/include/NVCtrl but I guess version is not correct since compilation
stops with an error about (I guess) a function in the header file.
libXNVCtrl includes are properly recognized.

It is probably a problem that should be fixed in nvidia-settings, prior to
sensors-applet (for which the "fix" is trivial, i.e. adding "--with-nvidia"
flag).

Thanks for your help!

Hi there,

I have tried doing the same as above using latest nvidia-settings
sources from Debian (1.0+20060516), but I get the same error, that I
report, on ./configure for sensors-applet:

[cut]
checking X11/Xlib.h usability... yes

configure: error: The NV-CONTROL library file cannot be used! make sure
you have installed nvidia-settings.
make: *** [config.status] Error 1
debuild: fatal error at line 1224:

Hope this helps!

The two problems with NVidia support are:

     1. The nvidia-settings package does not ship the libXNVCtrl library
     2. nvidia-settings is in contrib; depending on it would mean
        sensors-applet would have to go to contrib as well

Once libXNVCtrl is shipped by nvidia-setting, I intend to provide simple
instructions in the README.Debian on how to recompile the sensors-applet
package to enable NVidia support.

Hi! As of Mon, 16 Oct 2006 nvidia-settings is shipping libXNVCtrl and it's
include files.
I've been able to compile sensors-applet from source adding
--with-nvidia to debian/rules successfully; though I haven't been able
to find the sensor in the applet. I can see the temp and fan readings
with nvclock -i (extract below).

Already done, I'm just waiting for the package to be uploaded. :)

WRT configuration, I think I am in the same boat as you. nvclock is able
to read my sensors:

We believe that the bug you reported is fixed in the latest version of
sensors-applet, which is due to be installed in the Debian FTP archive:

sensors-applet_1.7.8+dfsg-2.diff.gz
  to pool/main/s/sensors-applet/sensors-applet_1.7.8+dfsg-2.diff.gz
sensors-applet_1.7.8+dfsg-2.dsc
  to pool/main/s/sensors-applet/sensors-applet_1.7.8+dfsg-2.dsc
sensors-applet_1.7.8+dfsg-2_powerpc.deb
  to pool/main/s/sensors-applet/sensors-applet_1.7.8+dfsg-2_powerpc.deb



A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you

I've played around with libXNVCtrl a bit and it seems that it just
doesn't work on my card. Could you please try the attached program and
see if you get the same failure that I do (XNVCTRLQueryAttribute
assertion failed)?

[crux@voodoo:~/Cosas/nv]$ ./nvtest
nvtest: nvtest.c:17: main: Assertion `XNVCTRLQueryAttribute (dpy, 0, 0,
60, &core)' failed.
Aborted

Same result here, hope you get some news from upstream about this.

So, it seems that libXNVCtrl can't read the sensors on our cards. I'm
not sure about how best to contact upstream (NVIDIA) about this.

What is your card's make and model, BTW? Mine is a Gigabyte GV-N68128DH
(Geforce 6600).

Assuming the code to read sensors from nvclock is reasonably clean, it
should be possible to replace sensors-applet's nvidia-sensors module
with one that uses the nvclock code, but that is a task for another
day. :)

Has there been any progress on these very old bugs?

There is now a separate libxnvctrl-dev package (in contrib) containing the
headers and a static library - this stuff was not really suited to the
nvidia-settings package. In case there are more things missing (more headers,
another library, ... there might be some additional code available in the
nvidia-settings source package), please let me know.
If you need a shared library, a patch would be welcome, I never looked into
the creation of shared libraries.

This has happened inbetween ... so someone needs to write a nvidia module for
sensors-applet which needs to go into contrib ...
libxnvctrl-dev) available in unstable?

And if this does not work, try to look here:
