Hello All! I am attempting to get a dual 1070 setup working on Debian 11.
lspci | grep NVIDIA 01:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce GTX 1070] (rev a1) 01:00.1 Audio device: NVIDIA Corporation GP104 High Definition Audio Controller (rev a1) 09:00.0 VGA compatible controller: NVIDIA Corporation GP104 [GeForce GTX 1070] (rev a1) 09:00.1 Audio device: NVIDIA Corporation GP104 High Definition Audio Controller (rev a1)
Debian seems to detect both GPU’s just fine. 01:00.0 is powering a DVI monitor, while 09:00.0 is powering a DVI and a HDMI. While Xinerama is on, I can get all three monitors to come up and work as a single, large desktop. I am attempting to have three separate desktops with 01:00.0 being the primary. I can make both screens on 09:00.0 turn on if I configure X11 with nvidia-settings as root and add them as separate X screens, however, the mouse is the only thing that is displayed over a black screen. I’m not sure what else to do as I have poked around in xorg.conf, changed the MultiGPU setting, tried different settings regarding the Screens, Monitors, etc. with no change no matter what was configured.
I attempted to place just this config in the xorg.conf as described here and was able to find them in Displays, but when I attempt to enable them, they remain off.
Section "Device" Identifier "nvidia" Driver "nvidia" BusID "PCI:1:0:0" Option "PrimaryGpu" "yes" EndSection
Once I’ve rebooted, I attempted to run:
Providers: number : 2 Provider 0: id: 0x1b8 cap: 0x1, Source Output crtcs: 4 outputs: 8 associated providers: 1 name:NVIDIA-0 Provider 1: id: 0x373 cap: 0x2, Sink Output crtcs: 4 outputs: 8 associated providers: 1 name:NVIDIA-G0
Then attempt this command as described in the post:
xrandr --setprovideroutputsource NVIDIA-G0 NVIDIA-0 && xrandr --auto
I receive this error:
xrandr: Configure crtc 4 failed
And even though I have three monitors hooked up xrandr is still only detecting a single one my primary GPU:
Monitors: 1 0: +*DVI-D-0 1920/531x1080/298+0+0 DVI-D-0
Googled around a bit but I havent found anything anywhere that seems to point me in the right direction so I figured why not start here. I have attached a nvidia-bug-report to this post as well. Thank you in advance!
