ads' corner

It was time to update my laptop, and I already knew that the update will bring Snap, and installs the Snap Firefox version. Along with many known problems. Previously the laptop was on 20.04 LTS, but this version is about to loose support.

I ran through the upgrade, and then added an Ansible Playbook to handle the Firefox installation, remove the Snap version and install the PPA version. Most of my laptop configuration is handled using Ansible Playbooks.

The new display showing HABpanel works quite nice. But occasionally the fullscreen browser will lose the network connection. As far as I can see, it's not a Wi-Fi problem of the Raspberry Pi, but still annoying: in the morning the browser shows a small red warning that the connection to the openHAB server is lost, time is still correct, but temperature and the status of other devices is outdated. To fix that, I have to leave fullscreen mode, hit reload - and then there is no keyboard for going into fullscreen mode again (that's using the F11 key).

The Raspberry Pi with the touch display for the home automation system is coming along nicely. One problem to solve: how to display the openHAB HABpanel, and which browser to use?

Firefox and Chrome don't run on Raspbian. However "Chromium" (the open source part of the Chrome browser) is. That's a good start. But how to start the browser automatically, and in full screen?
