Did you get anywhere with this? I am trying to get a similar system configure with Debian testing/buster and not getting anywhere beyond having two monitors on a single card recognised. I have three monitors, two on first card and 1 on second card. Only the ones of the first card are getting managed by Xorg. Although the second card and associated monitor are found by Xorg, I cannot seem to get Xorg to configure and actually use this third monitor. Details follow: $ dpkg --list '*nouveau*' libdrm-nouveau2:amd64 2.4.84-2 xserver-xorg-video-nouveau 1:1.0.15-2 $ lspci | grep VGA 03:00.0 VGA compatible controller: NVIDIA Corporation GM107GL [Quadro K620] (rev a2) 04:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 210] (rev a2) $ uname -a Linux xxx 4.13.0-1-amd64 #1 SMP Debian 4.13.4-2 (2017-10-15) x86_64 GNU/Linux Selected lines from Xorg.0.log: [ 3877.659] (--) NOUVEAU(0): Chipset: "NVIDIA NV117" [ 3877.659] (II) NOUVEAU(0): Creating default Display subsection in Screen section [...] [ 3877.693] (II) NOUVEAU(0): Output DVI-I-1 using monitor section rotated [...] [ 3877.768] (II) NOUVEAU(0): Monitor name: DELL U2412M [...] [ 3877.783] (II) NOUVEAU(0): Monitor name: DELL U3818DW [...] [ 3877.783] (II) NOUVEAU(0): Output DVI-I-1 connected [ 3877.783] (II) NOUVEAU(0): Output DP-1 connected [...] [ 3877.783] (--) NOUVEAU(G0): Chipset: "NVIDIA NVA8" [...] [ 3877.795] (II) NOUVEAU(G0): Output DVI-I-1-2 using monitor section rotated [ 3877.851] (II) NOUVEAU(G0): Output HDMI-1-1 has no monitor section [ 3877.862] (II) NOUVEAU(G0): Output VGA-1-1 has no monitor section [...] [ 3878.010] (II) NOUVEAU(G0): Monitor name: SHARP HDMI but then nothing is connected to this monitor or this monitor is not connected to anything... The strange thing is that the output says that output DVI-I-1-2 will use the "rotated" monitor section which has already been assigned to the DVI-I-1 output. I can post Xorg.0.log as well as my current xorg.conf if anybody is interested. Without an xorg-conf at all, I get the same effective behaviour: two monitors working but third one ignored. Any suggestions welcome. Thank you, -- : Eric S Fraga : in Emacs 27.0.50 + Gnus v5.13 + evil-git-5d040cd : BBDB version 3.1.2 (2017-01-30 14:47:26+00:00)
