I’m new to OpenSuse and trying to figure out how to add a third monitor. I’m not for sure what I need to do or what information I can provide to help guide me in the right direction. Under Yast2, I’ve the hardware information and under display:
**Just another thought - the type of plug is a HDMI that the monitor is going into - which the existing two are that also, but looks like those are plugging directly into the MB.

Not all motherboards with onboard video ports support using those ports at the same time as ports on an add-in gfxcard. If the board supports using all at once, then the BIOS should have options for which to prefer, typically IGP vs. PEG vs. PCI in various combinations.
Even when multiple ports are supported by hardware and BIOS, it can be perplexing to figure out what options might be required to have them all working. One test to make is booting to multi-user instead of GDM, and bypassing Plymouth, by appending
plymouth.enable=0 3
to Grub’s linux line. You might find as I often have that different combinations of displays light up on the framebuffer vttys than in the login GUI or DE. It’s not been uncommon for me to find only one or two light up until the greeter shows up, or have one or two go black when the other lights up as KMS switches the framebuffer mode.
Please provide output from:
inxi -Gxx
run from Gnome terminal or Xterm. You may need to install it first, either:
sudo zypper in inxi
, or get it directly from its developer who updates it far more often than openSUSE packagers, sometimes more than once a month.
Not for sure if I’m doing the plymouth.enable part right…
However, I found that unplugging the two monitors that are working and put them into the card, it still boots up and both monitors are working. This changed the result of the xrandr --query

Once I get back from a meeting, I’ll play around with the plymouth.enable part…
Hi
That doesn’t look like the monitors are plugged into the Quadro display ports and you using the onboard card, can you post the output from;
/sbin/lspci -nnk | egrep -A3 "VGA|Display|3D"
If it’s like this Intel M/B I can have the onboard GPU (Intel) enabled and run three monitors via display port and DVI connectors, but disables video output to the nvidia card (I can see the card and use the cuda cores though).
If the lspci output shows two GPUs, suggest you disable the onboard GPU via BIOS and then connect to the Quadro…
Card-1 is the onboard 8086:3e92 Intel UHD Graphics 630. Card-2 is the GP106GL [Quadro P2000].
Dell BIOS are generally very simplistic compared to motherboards in DIY PCs. On my Optiplex 780, the only choices for Video are Primary, under which are Auto, and Onboard/Card. A PEG card will unconditionally disable the onboard Intel. Does this Quadro have more than two outputs?
