I have an HP ZBook 15 G3 with a Quadro M1000 running Ubuntu 16.04. I have tried the nvidia 367.44 and 370.28 drivers from the standard graphics drivers PPA (https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa). In both cases, when I check the layout via the XineramaQueryScreens X11 call, I get inaccurate information. Only the two external monitors are reported; the internal laptop screen is ignored.
ghc -e “Graphics.X11.openDisplay >>= Graphics.X11.Xinerama.getScreenInfo”
[Rectangle {rect_x = 1920, rect_y = 0, rect_width = 1920, rect_height = 1080},Rectangle {rect_x = 3840, rect_y = 0, rect_width = 1080, rect_height = 1920}]
Graphics.X11.Xinerama.getScreenInfo is a pretty raw wrapper around XineramaQueryScreens. As you can see, only two screens are shown there. However, I have three screens, as is accurately represented in xrandr. The screen which is not included in the primary one.
Additionally, the monitor does not show up at all in nvidia-settings. It’s not listed in any drop-down and does not show up in the graphical display of monitor layout.
Optimus setup seems to have been configured by the installer script as my /etc/X11/xorg.conf looks like the version described “for older X servers” given here: Chapter 32. Offloading Graphics Display with RandR 1.4
I tried issuing the xrandr commands there with --setprovideroutputsource, but it did nothing. I note that xrandr --listproviders has a somewhat different output that I expected, with three shown:
Providers: number : 3
Provider 0: id: 0x269 cap: 0x1, Source Output crtcs: 4 outputs: 8 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x49 cap: 0x2, Sink Output crtcs: 3 outputs: 7 associated providers: 1 name:modesetting
Provider 2: id: 0x49 cap: 0x2, Sink Output crtcs: 3 outputs: 7 associated providers: 1 name:modesetting
I’m kind of stuck here. What should be my next step in debugging this? This is pretty out-of-the-box at the moment. I have not edited an Xorg confs, just installed packages. I tried disabling hybrid entirely but I got no display during boot and blind typing my disk encryption key didn’t get me an X login screen, so that route seems fraught. I’d be fine with giving up the battery life of sometimes using the Intel GPU though - this system doesn’t move around much.
