Failed to read display number from pipe.

My laptop has one integrated graphic card and a discrete Nvidia card. And I want to extend the display with another monitor. After following https://github.com/Bumblebee-Project/Bu … itor-setup, I get this error.

Failed to read display number from pipe.

My xorg.conf as follows:

Section "ServerLayout"
	Identifier "Layout0"
	Screen 0 "nvidia"
	Inactive "intel"
EndSection

Section "Device"
	Identifier "nvidia"
	Driver "nvidia"
	BusID "PCI:01:00:0"
EndSection

Section "Screen"
	Identifier "nvidia"
	Device "nvidia"
EndSection

Section "Device"
	Identifier "intel"
	Driver "i915"
EndSection

Section "Screen"
	Identifier "intel"
	Device "intel"
EndSection

Section "Files"
	ModulePath "/usr/lib/nvidia/xorg"
	ModulePath "/usr/lib/xorg/modules"
EndSection

How could I make it work?

Re: Failed to read display number from pipe.

You get this error "where"? Xorg log? SDDM? Other DM?
The config tries to drive the X11 server on the nvidia GPU. Using bumblebee there's a good chance you bbswitch'd off the GPU?

I got it when I tried to run 

optirun sddm

before logging in.
I have tried using bumblebee but I got "/dev/dri/card0: failed to set DRM interface version 1.4: Permission denied". I have tried many but I cannot handle this error.

Re: Failed to read display number from pipe.

optirun sddm

Yeah. No.

optirun is mutually exclusive from the approach you took above. From the article you linked:

article wrote:

If you can't get it to work with the two above methods you might try the following:

The conf you posted starts X11 on the nvidia chip, so it need to be active (the article stresses that) and you just have to eg. "systemctl start sddm"
You'll also have to make adjustments to the bumblebee config and set the correct provider output source in order to invoke the output wired to the intel chip (as detailed in said article)

Yeah, I think I have adjusted to bumblebee config but I still cannot make it work.

Re: Failed to read display number from pipe.

https://bbs.archlinux.org/viewtopic.php?id=57855

" I still cannot make it work" is not a usable problem description. Running "optirun sddm" is wrong or at least contradicts your xorg.conf, but it's also the cause for the original post. So right now we know nothing about your problem.
"I think I have adjusted to bumblebee config" isn't helpful either.

What *exactly* did you do and what *exactly* is the outcome.
And again: You don't want to "optirun sddm" at all.

Okay, how can I deal with

? The approach in https://wiki.archlinux.org/index.php/Bumblebee does not work.

Re: Failed to read display number from pipe.

Start with defining what you actually want, because again as stated we do not know what your actual end goal is. Do you still want to be able to turn off the dedicated GPU on the fly, like bumblebee would allow you? Or do you not care and just want to extend a second monitor "forever" ?

That's neither showing what you actually did, nor showing what the actual error message was that lead to your conclusion of "doesn't work".

Which section of that article did you follow?

But this will go in endless circles, start with the initial question, what do you want to do, don't worry (or let us help you) about the how for now.

Re: Failed to read display number from pipe.

Okay, my laptop has two graphic cards and now I want to extend the laptop's monitor to a new monitor. My goal is the monitor on the laptop use integrated card and monitor use discrete nvidia card.
Now my xorg.conf as follows

Section "Screen"
	Identifier "Screen0"
	Device     "intel"
	Monitor    "Monitor0"
EndSection

Section "Screen"
	Identifier "Screen1"
	Device     "DiscreteNvidia"
	Monitor    "Monitor1"
EndSection

Section "Monitor"
	Identifier "Monitor0"
	Option     "Enable" "true"
EndSection

Section "Monitor"
	Identifier "Monitor1"
	Option     "Enable" "true"
EndSection

Section "Device"
	Identifier "intel"
	Driver     "intel"
	BusID      "PCI:00:02:0"
EndSection

Section "Device"
	Identifier "DiscreteNvidia"
	Driver     "nvidia"
	BusID      "PCI:01:00:0"
EndSection

Section "Files"
	ModulePath "/usr/lib/nvidia/xorg"
	ModulePath "/usr/lib/xorg/modules"
EndSection

And now I get new error message:

Screen 1 deleted because of no matching config section

I follow the bumblebee wiki but this error still exits.

Re: Failed to read display number from pipe.

If you remove xorg.conf and start sddm or startx with both displays connected what is the contents of Xorg.0.log then?

Re: Failed to read display number from pipe.

You're running on the intel chip. The nvidia one isn't considered.

Okay, I installed bumblebee. But I still get thi error. The bumblebee config as follows:

Section "ServerLayout"
    Identifier  "Layout0"
    Screen 1    "Screen1"
    Option      "AutoAddDevices" "true"
    Option      "AutoAddGPU" "false"
EndSection

Section "Device"
    Identifier  "DiscreteNvidia"
    Driver      "nvidia"
    BusID       "PCI:01:00:0"
    Option      "AllowExternalGpus" "true"
    VendorName  "NVIDIA Corporation"

#   If the X server does not automatically detect your VGA device,
#   you can manually set it here.
#   To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data
#   as you see in the commented example.
#   This Setting may be needed in some platforms with more than one
#   nvidia card, which may confuse the proprietary driver (e.g.,
#   trying to take ownership of the wrong device). Also needed on Ubuntu 13.04.
#   BusID "PCI:01:00:0"

#   Setting ProbeAllGpus to false prevents the new proprietary driver
#   instance spawned to try to control the integrated graphics card,
#   which is already being managed outside bumblebee.
#   This option doesn't hurt and it is required on platforms running
#   more than one nvidia graphics card with the proprietary driver.
#   (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT).
#   If this option is not set, the new Xorg may blacken the screen and
#   render it unusable (unless you have some way to run killall Xorg).
    Option "ProbeAllGpus" "true"

    Option "NoLogo" "true"
    Option "UseEDID" "true"
    Option "UseDisplayDevice" "true"

Re: Failed to read display number from pipe.

You're completely missing the point. You fail to run X11 on the nvidia chip, because the nvidia chip is (most likely) deactivated.
Installing bumblebee isn't some magic solution (bumblebee allows you to dynamically invoke the nvidia chip - which is NOT AN OPTION - if you want to continuously drive an output on it) but the estimated cause of the deactivated nvidia chip.

Remove bumblebee and post the Xorg log of the failed server for the config you posted in comment #9 as well as a complete system journal ("sudo journalctl -b", you can utilize the tip from https://wiki.archlinux.org/index.php/Pastebin )
