Prevent Chromium auto-launch on boot (keep DWC running)

rkutun

Hello everyone,

I'm using a Raspberry Pi with DuetPi and I want to stop Chromium from automatically launching when the system boots. However, I still want Duet Web Control (DWC) to be running in the background (accessible via localhost), so I don't want to disable duetwebserver.service.

Here's what I've already checked:

I commented out @launch-dwc in both:
/etc/xdg/lxsession/LXDE/autostart
/etc/xdg/lxsession/LXDE-pi/autostart
I do not have a ~/.config/lxsession/LXDE-pi/autostart file.

No duetwebcontrol.desktop in /etc/xdg/autostart.

No launch-dwc call in .bashrc, .bash_profile, .xsession, .xinitrc, or .profile.

Yet, Chromium still launches automatically in full screen when the Pi boots.

I don't want to rename or override /usr/bin/launch-dwc, because I'd like to keep the system as clean and upgradable as possible.

My question: Where else might launch-dwc be invoked from during startup, and how can I prevent it from launching Chromium while still keeping DWC active?

Thanks in advance for any suggestions!

Check:
/etc/xdg/lxsession/LXDE-pi/autostart
~/.config/wayfire.ini
~/.config/labwc/autostart

It all depends on which windowing system you are using, X11, Wayfire, or Labwc
