I have yet another laptop which is a casualty of the proprietary Nvidia driver.  I would like to do CUDA development on the laptop (Dell Precision 5510 with Quadro M1000M and 4k display), so I want the proprietary driver.I have tried for several hours now, even reading through this, and I just don't know how to configure xorg when it won't autoconfigure.  I used nvidia-xconfig to set my xorg.conf initially, then I had to add a BusID setting to the Device section in order to find the card.  Now, startx runs without errors (and I can verify things are actually working), but it's like it's only showing on a ghost screen.  I can run DISPLAY=:0 xrandr remotely and I get a 8x8 virtual screen with no outputs:Screen 0: minimum 8 x 8, current 8 x 8, maximum 16384 x 16384I get the following chunk of Nvidia-related output in my xorg log file, with a couple of suspicious NULL values: (==) Log file: /var/log/Xorg.0.log, Time: Sat Jul 16 22:35:15 2016(==) Using config file: /etc/X11/xorg.conf(==) Using system config directory /usr/share/X11/xorg.conf.d(==) ServerLayout Layout0(**) |-->Screen Screen0 (0)(**) |   |-->Monitor Monitor0(**) |   |-->Device Device0(**) |-->Input Device Keyboard0(**) |-->Input Device Mouse0...(**) NVIDIA(0): Depth 24, (--) framebuffer bpp 32(==) NVIDIA(0): RGB weight 888(==) NVIDIA(0): Default visual is TrueColor(==) NVIDIA(0): Using gamma correction (1.0, 1.0, 1.0)(**) NVIDIA(0): Enabling 2D acceleration(II) NVIDIA(0): NVIDIA GPU Quadro M1000M (GM107GL-A) at PCI:1:0:0 (GPU-0)(--) NVIDIA(0): Memory: 2097152 kBytes(--) NVIDIA(0): VideoBIOS: 82.07.82.00.23(II) NVIDIA(0): Detected PCI Express Link width: 16X(II) NVIDIA(0): Validated MetaModes:(II) NVIDIA(0):     NULL(II) NVIDIA(0): Virtual screen size determined to be 640 x 480(WW) NVIDIA(0): Unable to get display device for DPI computation.(==) NVIDIA(0): DPI set to (75, 75); computed from built-in default(--) Depth 24 pixmap format is 32 bpp(II) NVIDIA: Using 12288.00 MB of virtual memory for indirect memory(II) NVIDIA:     access.(WW) NVIDIA(0): ACPI: AC power state information is not available under(WW) NVIDIA(0):     /sys/class/power_supply/ , nor under(WW) NVIDIA(0):     /proc/acpi/ac_adapter/(II) NVIDIA(0): Built-in logo is bigger than the screen.(II) NVIDIA(0): Setting mode NULL(==) NVIDIA(0): Disabling shared memory pixmaps(==) NVIDIA(0): Backing store enabled(==) NVIDIA(0): Silken mouse enabled(**) NVIDIA(0): DPMS enabledHere is my current xorg.conf:# nvidia-xconfig: X configuration file generated by nvidia-xconfig# nvidia-xconfig:  version 367.35  (buildmeister@swio-display-x64-rhel04-01)  Mon Jul 11 23:51:45 PDT 2016Section ServerLayout    Identifier     Layout0    Screen      0  Screen0 0 0    InputDevice    Keyboard0 CoreKeyboard    InputDevice    Mouse0 CorePointerEndSectionSection InputDevice    # generated from default    Identifier     Mouse0    Driver         mouse    Option         Protocol auto    Option         Device /dev/psaux    Option         Emulate3Buttons no    Option         ZAxisMapping 4 5EndSectionSection InputDevice    # generated from default    Identifier     Keyboard0    Driver         kbdEndSectionSection Monitor    Identifier     Monitor0    VendorName     LaptopBuiltin    ModelName      eDP1    HorizSync       28.0 - 33.0    VertRefresh     43.0 - 72.0    Option         DPMSEndSectionSection Device    Identifier     Device0    Driver         nvidia    VendorName     NVIDIA Corporation    #BusId          PCI:1:0:0EndSectionSection Screen    Identifier     Screen0    Device         Device0    Monitor        Monitor0    DefaultDepth    24    SubSection     Display        Depth       24    EndSubSectionEndSection
