Reattaching PCI device to dom0 via console. Error in documentation.

[alex...@tutanota.com]

The solution at http://qubesosfasa4zl44o4tws22di6kepyzfeqv3tg4e3ztknltfxqrymdad.onion/doc/pci-devices/

Bringing PCI Devices Back to dom0

echo <BDF> > /sys/bus/pci/drivers/pciback/unbind
MODALIAS=`cat /sys/bus/pci/devices/<BDF>/modalias`
MOD=`modprobe -R $MODALIAS | head -n 1`
echo <BDF> > /sys/bus/pci/drivers/$MOD/bind

is not working.

1st string - successful

2nd string - successful

3rd string - successful

4th string - error: -bash: /sys/bus/pci/drivers/$MOD/bind : Ambiguous redirect

4th string causes error and not working, so impossible to reattach pci device via console.

Previously i attached my (Primary) GPU to whonix-ws-15. When i clicked to start whonix-ws-15 my PC has reboot. Now after password entering while booting the system, monitor vision disappearing after few minutes. OS is booting normally but without monitor view.

I switched off system. Inserted 2nd Graphic card and when OS booted i can recieve view from 2nd graphic card but only in console mode. And i can not reattach my 1st Graphic card to dom0 because of represented error. qvm-pci always shows my card at whonix-ws-15. Meanwhile whonix-ws-15 switched to start while system booting but it doesn't.

Thank you.

Try removing the graphic card via qvm-pci or from whonix-ws-15 Qube
Settings/Devices.
