Multiseat with Nvidia & Intel

shahriar25 · 2016-06-05 06:07:42

Hi. I'm trying to set up multiseat on my hybrid laptop (with intel & nvidia graphics). I read an article about multiseat in the wiki and I understood that I have to attach my devices to the second seat and I have to start with the graphics card. now my primary seat uses the intel graphics and I want the second seat to use the nvidia graphics. this is the output when i run this command:
loginctl seat-status seat0

 seat0

my problem is that I don't know what is the nvidia device path in /sys/devices/pci... to attach to the second seat with loginctl. can anyone help?

Well since no one has answered let me ask a simpler question.
My laptop has two graphics and I want to attach the nvidia graphic to my cuttent seat. how can I do that?

https://wiki.archlinux.org/index.php/Xo … _to_a_seat

The nvidia card is the one that isn't the Intel one (fb0).

shahriar25 · 2016-06-06 13:02:50

well that is my problem. the Nvidia graphics is nowhere to be found in seat-status but it is there in the lspci. if you look at my first post you will see

positronik · 2016-06-06 13:17:55

Can't you just explore /sys/devices/pci* to see where your second Nvidia card is located, using some educated guesses from lspci output?

shahriar25 · 2016-06-06 15:49:58

I searched /sys/devices/pci... and I found it:

/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0

I tried attaching the above path and it printed that there was no such device (as I suspected)

what should I do now?

positronik · 2016-06-06 17:19:56

Post the command you used to attach the device

Edit: I guess you simply used the path that you've written. Don't you see that the command in the wiki specifies also a subfolder?

shahriar25 · 2016-06-06 17:46:55

this is the command and the output:

loginctl attach seat1 /sys/devices/pci0000\:00/0000\:00\:01.0/0000\:01\:00.0/
Could not attach device: No such device

and yes I noticed the subfolder in the wiki but I have no idea which one. this is the contents of the folder:

ls /sys/devices/pci0000\:00/0000\:00\:01.0/0000\:01\:00.0/
boot_vga                  enable         remove        resource5
broken_parity_status      firmware_node  rescan        rom
class                     irq            reset         subsystem
config                    local_cpulist  resource      subsystem_device
consistent_dma_mask_bits  local_cpus     resource0     subsystem_vendor
d3cold_allowed            modalias       resource1     uevent
device                    msi_bus        resource1_wc  vendor
dma_mask_bits             numa_node      resource3
driver_override           power          resource3_wc

which one is it?

positronik · 2016-06-06 18:17:59

Which driver you are using?

shahriar25 · 2016-06-07 04:04:56

I'm using bumblebee with NVidia drivers. I installed this section in this article:

https://wiki.archlinux.org/index.php/bumblebee
Installing Bumblebee with Intel/NVIDIA

positronik · 2016-06-07 05:58:48

I suppose that bumblebee deactivates your gpu but for using multiseat you need it enabled

shahriar25 · 2016-06-07 07:13:06

How do you suggest I do that? and what do I do after that?
I can enable it by running an application with optirun but that is a temporary solution

positronik · 2016-06-07 07:31:03

I don't have a laptop with a hybrid graphics setup and when I set multiseat I did it on a desktop computer.
My idea is that if you give up with any kind of power management utility such as bumblebee and have both cards active, you will probably find the drm bit in the /sys/* folder. But this is my guess, I think you will need to experiment by yourself, sorry for not being able to help you further!

shahriar25 · 2016-06-07 07:58:30

I searched the internet and I found a solution to switch the nvidia on with bbawitch

tee /proc/acpi/bbswitch <<<ON

and when I read the enable file in the nvidia device directory in /sys it prints :
1

is it enabled? (there is no drm file or folder in device path)

and thank you for helping this much

Have you succeeded?
