Hello! I have two nvidia 670GTX cards that I use in SLI in Win7 but in Suse one is just heating up the room. Is there any way to turn one of the cards off? I saw a bunch of threads about integrated graphics but nothing on my situation.
Thanks!
Are you using the NVIDIA driver? SLI should work if that is used. If so try the nvidia-settings program
Yes, I do use the NVIDIA driver but I don’t have a need for SLI in suse and wanted to find a way to turn one of the cards off. I want to do something like this but in Suse.
SUSE or openSUSE you do know they are different right???
Only way I could guess is through the nvidia-setting program. If you installed the driver the setting program is there also. Don’t have SLI here so can not really check. Maybe a question for NVIDIA??
It is openSuse, of course. There is no way to do it through the nvidia settings. I thought there is a way to stop kernel from powering up particular PCI or PCIe slot on the motherboard without blocking out the module with nvidia driver, because I still want to use the 1st card.
Edit: Thank you for replying btw!
Now that you’ve already seen that a name does matter, it’s openSUSE 
What’s the desktop used? I cannot test, but I assume that f.e. KDE’s systemsettings ( the kscreen module ) is able to disable the screen that is no doubt attached to the video card. Disabling that second “screen”, which isn’t actually there, could help. AFAIK GNOME has an option for this too. Both would not power off the card though. Blacklisting through 50-blacklist.conf is no use, both cards would be hit by that.
Omg, I am terribly sorry, m’lord! Please do not unleash the wrath of the openSUSE Gods upon my newbe soul!
I shall never call openSUSE anything other than openSUSE again. O:)

Thank you for the explanation! Yes, I use KDE Plasma 5. It is a shame that I cannot simply “disable” the hardware that I do not want to use. This could be a very useful part of openSUSE functionality. For example, someone else might have a webcam that they feel they want to disable from time to time…
Trouble is that there is a SUSE distro which is not the same as openSUSE. Often we get people here asking questions that pertain to SUSE so it is very important to keep the names straight.

Powering down hardware attached to a system bus would typically involve BIOS access/control to achieve. The kernel is otherwise informed of active devices and appropriate drivers loaded. In the case of a webcam attached to a USB subsystem it would probably sufficient to just unload the driver, or disable with a suitable udev rule perhaps.
