Disable weston autostart in STM32MP157C-DV2

[hochul yoo]

I am evaluate the STM32MP157C-DV2 board.

I tried to disable the automatic start of the weston service by referring to the wiki below.

https://wiki.st.com/stm32mpu/wiki/How_to_stop_and_start_Weston

root@stm32mp1:~# systemctl disable weston@root.service

root@stm32mp1:~# reboot

but it does not work properly.

Still the weston service will run automatically and a demo application will appear.

Status is static after disable as shown below.

root@stm32mp1:~# systemctl disable weston@root.service

root@stm32mp1:~# systemctl status weston@root.service

   CGroup: /system.slice/system-weston.slice/weston@root.service

       > 3884 /usr/bin/weston --log=/var/log/weston.log --xwayland

What's the problem?

Thank you in advance.

Hi @hochul yoo​ ,

Sorry the wiki page was not up-to-date, this is missing informations ( added in couple of days) :

The Weston service is automatically started on boot thanks to an udev rules file, most of the time located in /etc/udev/rules.d/*weston*, for instance /etc/udev/rules.d/71-weston-drm.rules.

To disable this service, rename this file (by changing its extension for instance), then restart your board.

To re-enable this service, rename this file according to the udev rules of your system.

Hope it help

Olivier
