 |
|
hello everybody!
i've recently discovered app-mobilephone/scrcpy::maggu2810-overlay, an excellent application that let you control your android smartphone while docked on your pc's usb port...
my intention was to start the application automatically when the phone is plugged, so i've added the following udev rule:
| Code: | # cat /etc/udev/rules.d/20-phone.rules
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="22b8", ATTRS{idProduct}=="2e81", RUN+="/usr/local/bin/moto.sh"
# cat /usr/local/bin/moto.sh
#!/bin/sh
su skunk -c /usr/bin/scrcpy
|
unfortunatelly nothing happens after plugging the phone:
| Code: | [950475.568435] usb 2-1.6: new high-speed USB device number 12 using ehci-pci
[950475.647947] usb 2-1.6: New USB device found, idVendor=22b8, idProduct=2e81, bcdDevice= 3.18
[950475.647951] usb 2-1.6: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[950475.647953] usb 2-1.6: Product: Moto G (5)
[950475.647954] usb 2-1.6: Manufacturer: motorola
[950475.647956] usb 2-1.6: SerialNumber: ZY3222W47R

yes, i did run "udevadm control -R" and /usr/local/bin/moto.sh script is working correctly when executed manually by root
please, is somebody so kind to tell me what i'm missing?
thank you

First, I would check if the script actually runs. Try adding "echo device connected >> /tmp/moto.log" to your shell script.
Maybe also add tee to capture the error message: "su skunk -c /usr/bin/scrcpy |& tee -a /tmp/moto.log"
My guess is it's a graphical application and it's missing the DISPLAY env variable and so can't connect to the X server.
