Electronic privacy screen system status icon and OSD notification on on/off toggle
Some laptops, such as e.g. the Thinkpad T490s now come with a built-in electronic privacy-screen, which reduces the viewing angles to make it harder for people to shoulder-surf.
This has already been discussed by (off-list) email a bit. In the email discussion 3 options where brought up for the UI for this:
- Show an icon in the system status icon area (where e.g. also the sound-volume and network status icons sit) when the privacy-screen is on.
- Show on OSD iconic message when the privacy screen is toggled on/off through the hotkey controlling it, like when we do when e.g. the speaker volume is (un)muted.
- Do both 1. and 2.
Note there already has been filed an issue to design on/off icons for 2. see GNOME/adwaita-icon-theme#90 (closed), if we decide to not do 2. then those icons will not be necessary.
