Default 260.19.21 Fermi Triple SLi and Fan Control + VDPAU + Overclocking?

Hey everyone this is my first post so ill get straight to the point....
I really wish these drivers would work somewhat decently. First complaint:
I can live with the Fermi sli not working, but when sli is off, why cant I enable the fanspeed control for those cards so when I use them for CUDA applications I can keep them cool. The driver does a horrible job at this, locking the fanspeed at 45% no matter what temp the card is at. The only way to enable fanspeed control is by enabling SLI, rendering the system HIGHLY unstable and almost guaranteed to lock up in a very short time.

Second Complaint:

Can we please get some overclocking support with fermi's as well. That would be nice.

Third Complaint:

Not as big of deal I guess, but when these issues are being fixed, please dont forget to make VDPAU work with Fermi's in SLI. I recently dropped a very large sum of money to SLI three GTX 480's and am hugely dissapointed in the drivers. Why are Linux users "being treated as second class citizens" (saw in another post). These drivers are not far from being alright! Just a few more things to work out and there will be alot of happier customers using open source software. Please fix these issues soon.
Thanks

Hi and welcome to the forums. I'm sorry to hear you're having problems, but I'm also very glad that you're taking your time to write down these SLI driver issues. It's going on for quite some time now and hopefully the devs will see the increasing demand to fix this asap.

If it can be of any consolation, the devs stated that they are going to look into better SLI support for Linux, but it's not high on they priority-list.

Have you tried to enable Option Coolbits 5 in your xorg.conf? This will allow manual fan speeds and will unlock the overclocking abalities in nvidia-settings (still not working for Fermi though, as you know)

Good luck.

Hey,

Thanks Ulakai, I tried using fan control with coolbits set to four after I found one didnt work. I want to clarify some things as well, without sli my main display card still has fan control but I lose fan speed control on the other two gtx 480's. And then I try to use my wpa security auditing software that is cuda enabled and all the sudden gtx 480 #2 is at 92 degrees celsius with the fan speed still at 45%!!!

Another issue I am having is trying to use my supreme fx x-fi soundcard, which does not work by default in ubuntu maverick when you have these fermi's installed. I would like to use the mic in on the x-fi to connect to my walkera model heli remote to use in heli-x which i recently paid 70 euros for. That is not really related I know, I just wanna give as many people as possible a heads up on these issues to help when they arise. If your interested I have started this topic in a forum in ubuntu. (its a solvable codec issue which when solved seems to break fermi hdmi audio)

Anyways, keep up the good work Nvidia team its nice to see you do respond and listen, from what Ive seen so far. Lets try to get some good drivers out before christmas so us open source geeks can show off our new hardware!

I have a GTX 470 of my own and as far as I see, the fan is programmed to keep the temps under 90 - 92 degrees (load) or 70 degrees (idle). They will only start ramping up once you reach these values. I'm waiting for Nibitor to include managing fan speeds on Fermi cards to make my own custom fan profile.

Concerning your audio issue, I'm not really into HDMI audio because I didn't need using it yet. But it sounds like a matter of loading the correct kernel modules and getting your audio device order straight. I believe Nvidia HDMI uses the HDA_intel module (or something similar) but I'm not quite sure about that. Probably your X-fi card needs another module and this should be configured as your default card.

Ulakai, the X-Fi soundcard also uses the snd-hda-intel module as well, and I am starting to believe this to be the cause of my issues. If I force one to work the other will not work and when both are forced no sound inputs/outputs work at all lol. I tried kernel 2.6.35-22 on ubuntu maverick and it almost seemed to work but i got many messages I have never seen before.

Anyways I filed a bug with alsa and hopefully they can figure it out. I have a few posts going on ubuntu forums and I have done many, many hours of googling and have not found anyone with an issue remotely close to mine which, to be honest, is not that surprising because of the newer hardware and drivers required for them.. Ill let you know what the problem was when its fixed.

cheechr1,

Can you please explain your VDPAU problem in more detail. To the best of NVIDIA's knowledge, VDPAU works correctly with SLI enabled, on Fermi or any other supported GPU generation. Please also included an "nvidia bug report" (see forum stickies) generated after you experience your problem. Thanks.

Hi Stephen, I am not sure I will be able to recreate the problem since I have upgraded and re-installed ubuntu a few times since the problem ocurred. I believe now it may have been an incompatibility with the smplayer and vdpau drivers I was using. I believe it was on ubuntu 10.04 at the time with 260.19.12 drivers, cannot recall exactly which kernel it was at the time. The problem would not be so bad with lower quality videos but high definition video would stutter and freeze the computer within a couple of seconds. Hopefully my cod black ops download will finish soon so I can reboot into sli and try to recreate the issue. Thank you for your interest in the matter I would love to see excellent linux nvidia drivers and am very happy to help.

P.S. Can we please get good SLI fermi support soon? I am tired of the crap microsoft puts out every few years to be my only option for overclocking and sweet graphics.

Hello again Stephen. Attached is a bug report from what may be a vdpau + fermi sli issue. When I booted up with sli enabled and opened smplayer, there was an almost immediate crash with artifacts. The second time I booted I tried to write this reply but the X server became slow and barely responed to inputs. Good thing I had already turned off SLI during the second boot because SLI with Fermi on 10.10 is very unstable, and I hate doing hard reboots. I made that bug report during the second boot. Just to let you know as well, I always use the enhanced zoom function in compiz as I run 1080p and it is often too small to read the screen. I noticed, using the enhanced zoom with SLI enabled, that the screen becomes very jumpy as the cursor goes across the screen. I hope this bug report will help. If you have any questions or concerns please let me know.

BTW, I fixed my soundcard issues ulakai. I resinstalled ubuntu 10.10, keeping the x-fi enabled in the bios the whole time. Then I added the audio-dev ppa and had to add this line to default.pa to keep hdmi audio working with still being able to use the x-fi for audio input:

load-module module-alsa-sink device=hw:1,7

The only problem so far is that I cannot get audio to work with good old Alpha Centauri which I believe uses SDL audio. I tried a bunch of different options with no good results. Oh well its still and Awesome game without audio.

Glad to hear your sound issue is fixed. I'm running Arch Linux myself and don't have PulseAudio installed, just trying to keep it as simple as possible. I don't quite get the whole PA stuff, why would every PC need a sound server? Alsa is working like a charm here, I can play everything simultaneously and all my propietary games are running fine
