I can't be certain of what the behaviour should be in this specific instance but it seems to me that when one specifies a specific choice and it cannot be found an error should be generated and I didn't see one. As I also said, I'm grasping at straws so I notice any anomalies and try to systematically remove any room for doubt so that I'm left with certainty. That's just how I troubleshoot the less than obvious.

Yes, you need it with a Intel/nvidia setup if you want to use the nvidia card for rendering. You also should specify the BusID for both cards and the drivers to use, i.e. "nvidia" and "modesetting" respectively. I have Slackware64-14.2, intelHD and GTX1060. I had to get the latest kernel (4.16.10 at the time), because the older one woudn't recognize the intel card, but otherwise it runs OK. For the record, my xorg.conf:

Code:

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

Section "Module"
        load "modesetting"
EndSection

Section "Device"
    Identifier "intel"
    Driver "modesetting"
    BusID "PCI:0:2:0"
    Option "AccelMethod" "None"
EndSection

Section "Monitor"
        Identifier "Monitor0"
        Option "DPMS"
EndSection

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

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1:0:0"
    Option "ConstrainCursor" "off"
EndSection

Section "Screen"
    Identifier "nvidia"
    Device "nvidia"
    Monitor "Monitor0"
    Option "UseDisplayDevice" "None"
    Option "AllowEmptyInitialConfiguration" "on"
    Option "IgnoreDisplayDevices" "CRT"
EndSection

Hi Millgates,

You cards have exact same PCI ID's as mine

I want to ask, in the below command:

Code:

xrandr --setprovideroutputsource modesetting NVIDIA-0

Where you get the string NVIDIA-0? Will it be same as in my case?

And, thank you for you xorg.conf, I will use it to do another try.

It should come out of xrandr:

Code:

$ xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x1f8 cap: 0x1, Source Output crtcs: 0 outputs: 0 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x49 cap: 0x3, Source Output, Sink Output crtcs: 3 outputs: 7 associated providers: 1 name:modesetting

That is assuming you have the nvidia driver enabled. I've had 3 or 4 laptops with this setting and the id was always NVIDIA-0 so there's a good chance it will be the same in your case.

@millgates, Another question is, I saw you have two Screen section in your config, one use intel the other use nvidia, what does it mean?

To be honest, I don't really know. I think both cards need to have a screen associated with them. Some xorg.conf examples for optimus such as this one have those so I put it there. Usually, the nvidia card has no physical output and can only be connected to the screen through the intel card, so the Option "UseDisplayDevice" "None" is there to tell the X server to not expect a monitor connected to it. As for the intel device section, I'm not sure whether or not it needs to be explicitly specified, but it doesn't seem to hurt.

Good to know this!

@millgates,

I basically copied your xorg.conf and the xrandr command lines, still cannot start X with the nvidia driver, the screen simply halt with a white cursor stay in the upper left corner forever. Attached is the log.

millgates · 06-27-2018, 09:06 AM

Can you give the output of xrandr --listproviders while the X server is running?
(you can either swith to a tty with ctrl+alt+F1 and run

Code:

DISPLAY=:0.0 xrandr --listproviders

or put the command in the .xinitrc startup script. You are using runlevel 3 and startx, right? Did you put the commands I mentioned earlier to your .xinitrc? They should go right before the window manager is started. Which WM/DE are you using?

The OP's setup may introduce different problems, but, FWIW, I have not had any problems with the DUSK-4.17.1, 4.17.2 and 4.17.3 kernels, xorg-1.20.0, and the Nvidia-390.67 driver.

millgates · 06-27-2018, 10:48 AM

Looking at your Xorg.0.log, it seems that your xserver loads module intel for your intel card while it should be loading modesetting instead. Are you sure your kernel is built with KMS suppport?

My X server can only use intel driver for the i915 intel card. Days before I tested and found if I use modesetting driver, the X cannot started. How can I know whether my kernel already with KMS enabled? (I guess it is, because when the system boot up, the font at some stage getting very small and the console resolution switched to a higher one)

BTW: xrandr commands were put in .xinitrc just before 'startkde'

If you want to use the nvidia card, ithink you need to use modesetting driver for intel.

Yes, but back then you probably didn't have the required commands in your .xinitrc. I suggest you try again now, and if it fails, post the xorg.0.log again.

This looks good. Both cards are recognized.
