I regularly have some webcams open on one of the monitors of my computer. I would like to be able to open them in full screen mode, but have each "full screen" be only 1/4 of the whole screen.

Here's how I view them at present:

enter image description here

I would like to have each webcam run in full-screen mode so that I get larger pictures and avoid wasting screen space with all the window frames, toolbars, etc.

Is there any way I can do this? My web browser of choice is Google Chrome and I'm using Ubuntu 18.10

NB I have a second monitor connected to my computer too, so any solution needs to take that into consideration too.

Xephyr is a partial solution, but it seems I need to run a new instance of the browser with it's own profile in order to be able to have it display to a separate X display. See https://unix.stackexchange.com/questions/197188/can-i-put-multiple-x-windows-into-a-single-larger-window

    You could write a webpage (HTML and CSS) that splits the screen into 4 and displays each of the feeds in it's own quadrant. That would give some extra space to make the videos larger. Getting help with this, however, would be off-topic here as it is a programming question. – DavidPostill Jan 20 at 17:07

With Vivaldi that is easily possible.

  1. Install Vivaldi

  2. Enable Tabgroups in vivaldi://settings/tabs/ Tabgroups

  3. Open your camera feeds in separate tabs

  4. If they all have the same domain just right click one tab and select Stack Tabs by Host [number of tabs and domain] if they are not from the same domain just drag and drop them slowly on top of each other until one gets grayed out. Stack Tabs

  5. It should look like this now: Stacked Tabs

  6. Tile all four (or more) tabs by an even grid: enter image description here

  7. It should now look like this Tiled Tabs

  8. Scale them to size with holding Ctrl and scrolling with your mouse wheel or + and -.

The active Tab is marked by a thin red border and it's URL is displayed in the addressbar.

If you want to, you can press F11 to hide all unnecessary things like addressbar or menu button.

    You have to drag it so, that the tab you want to stack onto gets greyed out – Nordlys Jeger Jan 25 at 0:19

    @K7AAY It's a bit tricky to get it right at first but you learn how to use it. – Nordlys Jeger Jan 25 at 0:20
  • Aha! SLOWLY drag tab Y atop tab X until tab X goes gray. – K7AAY Jan 25 at 0:22

    Just allow it to reopen the last used session? – Nordlys Jeger Jan 25 at 0:33

    I'm sure you could do it with a command but I already shut down my PC as I'm going to bed – Nordlys Jeger Jan 25 at 0:35
