Fan control

[sinatosk]

Does nvidia plan to bring fan control for Linux by Graphic User Interface, Command Line and maybe API for the GTX 200 cards ( GTX 260, GTX 260 216, GTX 280 )?

I don't know about the Geforce 8 and 9 series cards as I skipped them

I have a BFG NVIDIA GeForce GTX 260 OCX MAXCORE 896MB ( 216 SP ) and since then I've been using Windows more than Linux when playing games simply because there is no fan control and nvclock no longer works for me and I don't like that it runs at 40% all the time when playing games.

Yes I prefer Linux over Windows and I'm sick of dual booting

Thankyou

The NVClock cvs version should work for you.

[sinatosk]

I tried compiling it ( Ubuntu 8.04.1 ) and I keep getting compile errors

[sinatosk]

ok it compiles now... dunno why. This is what I do

$ cvs -d:pserver:anonymous@nvclock.cvs.sourceforge.net:/cvsroot/nvclock login
$ cvs -z3 -d:pserver:anonymous@nvclock.cvs.sourceforge.net:/cvsroot/nvclock co -P nvclock

and then after

$ cd nvclock
$ ./configure
$ make
$ sudo make install

and then after

$ nvclock --info

and I get this output

any reasons/suggestions? ( I havn't changed the source code )

Thanks

[Thunderbird]

Fun .. Try to edit src/Makefile and src/backend/Makefile in there add the option '-g' to the gcc line. Then perform a make clean and recompile. Then launch nvclock using gdb (gdb nvclock and then type 'run -i' in gdb) and create a backtrace (type 'bt' when it crashes). Hopefully I see some more then.

[sinatosk]

ok this is all of it from the command I typed in to the end

I had to run the configure script before I could see the "Makefile" ... all I saw before was "Makefile.in" and I added "-g" to all of the make files incase anything extra showed up

Hmm, line 842 of nvclock.c contains 'nvclock.dpy = XOpenDisplay("");' I guess XOpenDisplay is failing but I'm not sure yet why.

Could you try ./configure --disable-nvcontrol to see if that works. I want to fix the crash anyway but first I want to know if this is the issue.

[sinatosk]

and ironically the time when I said earlier in this thread

I tried compiling it ( Ubuntu 8.04.1 ) and I keep getting compile errors

well... it's the same error

so it looks like I might need it. the function "NVGetAttribute" is needed which is part of nvcontrol

[Thunderbird]

I fixed a compile error which prevents those two NVGetAttribute calls.

ok, what did you do to prevent that? I assume you just comment out the lines

so I disabled nvcontrol, commented out those 2 function calls and compiled alright but I still get that error

I looked at line 605 in "nvclock.c" and this is it

if(!init_nvclock())

considering that line worked before with no problems but then disabling nvcontrol now gives me an error at that line and glibc is telling me it's something to do with "free()" again...
