restart arch linux and use vuture luma ultra as the only display device start failed.

[zw963]

Following is the details:

My system info:

Arch Linux + GNOME 50.2, minisforum mini PC, AMD 7840hs with 780M iGPU, driver and rOCM config work well (because I can use 100% GPU when play gemm4:26b use ollama)

breezy-desktop-gnome-git 2.9.8-1

Following is the reproduce:

1. enable the user space xr-driver service.
2. plugin out the monitor, plug in the vuture glasses, as the only display device, then reboot my linux.
3. after start, the xr-driver start failed, with following log:

try restart the service get same error.

The only way to fix it is: plugin out the glasses, then plug in again, then restart the xr-driver service, after sow the calibrating message, It's start to work again.

I workaround this use following bash script:

#!/bin/sh

# viture-coldbootfix.sh

sleep 1;

if ! grep -q '^35ca$' /sys/bus/usb/devices/*/idVendor 2>/dev/null; then
    exit 0
fi

if systemctl --user is-active --quiet xr-driver.service; then
    exit 0
fi

sudo udevadm trigger --action=add --attr-match=idVendor=35ca
sudo udevadm settle

sleep 1

systemctl --user reset-failed xr-driver.service >/dev/null 2>&1 || true
systemctl --user restart xr-driver.service

echo "done"

exit 0

But, I thought this issue really can be fixed from xr-driver side anyway.

Thanks
