Ways to share screen for students is limited, especially for Turtle Blocks

[pikurasa]

I taught a group of kids today, and I decided to use our classic Turtle Blocks on Sugar (on Trisquel).

One thing that made it particularly difficult as an instructor is a lack of a way to display my screen to a large screen or projector, especially for Turtle Blocks because of the way it utilizes its frame.

Here are some of my notes:

• I don't see an obvious way in Sugar's settings to share my display.
• A workaround to the above, I found, is to go to the main desktop, in this case MATE, and share my display, then go back into Sugar and continue.
• Turtle Blocks displays across both screens in Sugar, despite being set in MATE to "mirror displays". It's impossible to show what I'm doing on my screen on the big display. The toolbar, for example, will only display on my main screen.
• I tried installing Turtle Blocks from Flatpak and displaying from my main desktop, which is using GNOME3 (without Wayland because that causes other headaches for me). I thought this would be a clever workaround for, at least, displaying Turtle Blocks. However, it displays across several screens and doesn't seem to use GNOME's way of managing frames, so I cannot change its size in any way (see screenshot below).

(The above image is across two screens. The left side is my laptop screen. The right side is the screen I'd like to display to.

Note: The help says I'm on version 220-54

I just now tried mirroring displays for Turtle Blocks in GNOME, and that seems to scale to the correct size.

I cannot, however, seem to resize it if I needed to.

I don't think Sugar has support for sharing your display from Sugar.

Dragging the window doesn't resize it or it doesn't scale to the right size when it resizes?

Understood. It would be nice if it did, but I would understand if it isn't a priority.

• In GNOME3, you can usually right click the edge of the frame to get scaling options. You cannot do that in the Turtle Blocks Activity from Flatpak
• Likewise, you cannot resize from the edges like you can do in other GNOME3 window frames
• When displaying on two displays without mirroring, you get what you see in the first image above, a frame that tries to fill the total width of both displays.
