<div dir="ltr"><div>Hi Benoit!<br><br></div>I guess you forgot to tag your seat1 card as "master-of-seat".<br></div><div class="gmail_extra"><br><div class="gmail_quote">2015-09-02 6:52 GMT-03:00 Benoit Barthelet <span dir="ltr"><<a href="mailto:benoit.barthelet@gmail.com" target="_blank">benoit.barthelet@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">long story short I had a working multiseat setup with 2 GPU / 2 mices<br>
and 2 keyboards<br>
<br>
I changed GPU drivers from open-source radeon to fglrx and it stopped working<br>
<br>
before the driver change I had configured the 2nd seat to used the gpu<br>
/ mice / keys with :<br>
<br>
loginctl attach seat1<br>
/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0/drm/card0/<br>
etc..<br>
<br>
the issue with the new drivers it seems is that I can't find the card0<br>
in the /sys hierarchy,<br>
<br>
for instance, it seems to be one of my card, but no seat tag :<br>
udevadm info --query=all<br>
--path=/sys/devices/pci0000:00/0000:00:07.0/0000:03:00.0<br>
<br>
P: /devices/pci0000:00/0000:00:07.0/0000:03:00.0<br>
E: DEVPATH=/devices/pci0000:00/0000:00:07.0/0000:03:00.0<br>
E: DRIVER=fglrx_pci<br>
E: ID_MODEL_FROM_DATABASE=Tahiti PRO [Radeon HD 7950/8950 OEM / R9 280]<br>
E: ID_PCI_CLASS_FROM_DATABASE=Display controller<br>
E: ID_PCI_INTERFACE_FROM_DATABASE=VGA controller<br>
E: ID_PCI_SUBCLASS_FROM_DATABASE=VGA compatible controller<br>
E: ID_VENDOR_FROM_DATABASE=Advanced Micro Devices, Inc. [AMD/ATI]<br>
E: MODALIAS=pci:v00001002d0000679Asv0000174Bsd0000E207bc03sc00i00<br>
E: PCI_CLASS=30000<br>
E: PCI_ID=1002:679A<br>
E: PCI_SLOT_NAME=0000:03:00.0<br>
E: PCI_SUBSYS_ID=174B:E207<br>
E: SUBSYSTEM=pci<br>
E: USEC_INITIALIZED=4263516<br>
<br>
So I tried to create manually a udev rule<br>
<br>
/etc/udev/rules.d/71-ati.rules<br>
<br>
SUBSYSTEM=="pci",<br>
DEVPATH=="/devices/pci0000:00/0000:00:01.0/0000:01:00.0", TAG+="seat",<br>
TAG+="master-of-seat"<br>
SUBSYSTEM=="pci",<br>
DEVPATH=="/devices/pci0000:00/0000:00:07.0/0000:03:00.0", TAG+="seat",<br>
TAG+="seat1"<br>
<br>
and now loginctl seat-status seat0 gives a master tag after udevadm trigger :<br>
├─/sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0<br>
│ [MASTER] pci:0000:01:00.0<br>
<br>
but I can never have a seat1, it never appears so the display manager<br>
never tries to launch 2nd X session )<br>
<br>
I'm at a loss here. any help appreciated<br>
