Xrandr cannot set DP port with Nouveau drivers

Hey everyone,

I'm having trouble getting multihead to work with xranr.  I'm using a Dell XPS 14z with discrete Nvidia graphics and an Intel card (Optimus).  I'm using the Nouveau driver as I was having too many issues with the proprietary Nvida driver.


--- ~ » lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [GeForce GT 520M] (rev a1)
--- ~ »

Xrandr can see and set both output providers:

--- ~ » xrandr --listproviders 
Providers: number : 2
Provider 0: id: 0x9e cap: 0xb, Source Output, Sink Output, Sink Offload crtcs: 3 outputs: 5 associated providers: 1 name:Intel

--- ~ » xrandr --setprovideroutputsource nouveau Intel
--- ~ »

The laptop has three outputs: laptop screen, HDMI, DisplayPort.  The DisplayPort is hardwired to the Nvidia controller, and the other two handled by the Intel controller. So far, Xrandr is recognising all of them are connected and shows them as LVDS1, HDMI1 and eDP-1-1 respectively (furthermore, the eDP-1-1 is showing the correct resolutions of the connected monitor):

So far so good.  However, while both LVDS1 and HDMI1 are working exactly as expected (I can use them dual, mirrored or individually), eDP-1-1 shows nothing on the connected monitor regardless of what configuration I try with Xrandr.

I'm not an expert on graphics hardware (yet, haha), so I'm probably missing something essential. Any ideas on where I should start?

Thanks,

Re: Xrandr cannot set DP port with Nouveau drivers

Are you setting your monitors up directly with xrandr or are you using a .conf file for X11? The Wiki page on Nouveau has a pretty good base template for an X11 config that you can set up.

Secondly, I know that some (a lot) of older Nvidia cards do not support more than two monitors at once. I'd recommended look up your card and seeing if this is possibly the case.

Re: Xrandr cannot set DP port with Nouveau drivers

Hi FoxzTrot,

Thanks for the reply, I appreciate it.  I'm using xrandr directly at this point as a means of testing that the DP output works before messing around with xorg.conf files. As far as I can tell, this is an issue specifically with the Nouveau driver rather than the hardware.  I know this because:

  1. I've used this laptop to run three monitors simultaneously in Windows in the past, with no problems.

  2. I've managed to get three monitors working in Linux using xrandr with the Nvidia proprietary drivers, but was having other issues with that driver that caused x-server to fail on boot, causing my login manager to loop/fail indefinitely.  Also the Nvidia drivers require a messy hack to get the card to work with the intel card.

  3. My immediate problem isn't that I can't get multiple outputs; it's that I can't get anything from eDP-1-1, even independently.

Also, the Nvidia card is only running a single output (DisplayPort); the other two (HDMI, LVDS) are handled by the Intel card.

Xrandr is behaving like the screen is attached and working; I can see the mode selected for the eDP-1-1 line after trying to set up the output:

--- ~ » xrandr -q
...
eDP-1-1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 473mm x 296mm
   1680x1050     59.95*+
...

Also, nothing in the xorg log jumps out at me:

It's like Nouveau "thinks" it's doing its job, but nothing is being sent to the monitor.

Note: I've tested the monitor and cable with another machine, so it's fine.

Any other ideas?

EDIT: When I say I'm using xrandr directly, I mean no xorg.conf files at all; everything is default at this point.

Re: Xrandr cannot set DP port with Nouveau drivers

Hmm well I don't have anything close to similar hardware so I can't fiddle with things myself, and there's little to no documentation about any similar problems. So, I can't help much....

However, since you could get things working with the Nvidia drivers, I would try setting up a working xorg .conf while using the Nvidia drivers  (either manually or with nvidia-settings), and then adapt that configuration for nouveau: 

Section "Device":
    Identifier "nvidia card"
    Driver "nouveau"
...

And switch back to nouveau, using that configuration file.

Hopefully, this might get things working.

Re: Xrandr cannot set DP port with Nouveau drivers

I've been playing around with this on-and-off for a couple of weeks now and still no luck.  Worse still, my last update broke the configuration I had with the Nvidia drivers, so now neither are displaying the screen on the DP.  I haven't been able to work out exactly what broke it yet.

I'll keep trying and post back here if I figure it out.

Re: Xrandr cannot set DP port with Nouveau drivers

Ok, so I don't know why I did look here before (or maybe I did, I can't remember), but dmesg is throwing up errors related to the nouveau driver:

dmesg | grep -i nouveau
