[agl-discussions] Disabling de,p homescreen/windowmanager

[tanikawa.tadao at jp.panasonic.com]

Hi Matsuzawa-san,

Currently symbolic link of HomeScreen.service and WindowManager.service which enables automatically boot are placed onto the directory which cannot be handled by 'systemctl --user' command.

To switch off HomeScreen/WindowManager,

 1) stop them manually every time after booting by following instruction.
    # systemctl --user stop HomeScreen
    # systemctl --user stop WindowManager
    # systemctl --user stop InputEventManager
    # systemctl --user stop HomeScreenAppFrameworkBinderAGL

    NOTE: Event if you did all this commands, screen doesn't change anything because currently HomeScreen and WindowManager don't care about cleaning up ivi-surfaces/layers which they used.

 2) disable them not to boot automatically by following instruction.
    # rm /etc/systemd/user/default.target.wants/HomeScreen.service
    # rm /etc/systemd/user/default.target.wants/WindowManager.service

    Then reboot system.

    If you want to recover auto-boot HomeScreen/WindowManager,
    # systemctl --user enable HomeScreen
    # systemctl --user enable WindowManager

    NOTE: After using 'enable', symbolic links placed under /home/root/.config/systemd/user/default.target.wants/.
    So after that, you can disable|enable HomeScreen/WindowManager by 'systemctl --user disable|enable'.

Regards,
Tadao Tanikawa

Subject: [agl-discussions] Disabling de,p homescreen/windowmanager

Hello, AGL.

This may be a trivial topic, but I am not sure how to.




I want to switch (dynamically, or as boot default) between AGL demo homesceen/windowmanager and my own one.




To accomplish this, first I think I need to stop them.

But systemctl --user disable HomeScreen.service, etc. does not seem to have effect.

The screen does not change, and if I reboot the board, AGL window manager and homescreen are automatically run.

(But if I see them through systemctl list-units, etc. their status is 'disabled'.)




Is there a quick way to do this, rather than removing their recipes from the build tree (it means rebuild)?
