Ubuntu – Evince shows small frame in Presentation mode

evincepdfpresentationslideshow

I recently noticed that Evince started showing the following unusual behavior when in Presentation mode (after F5 is pressed) on my laptop: instead of making the slide occupy most of the screen, it keeps it to a pretty low dimension, and fills the rest in black, as in screenshot below.

Zooming seems disabled in Presentation mode, despite working outside Presentation mode, and I couldn't find any other related options to adjust, so I can't find a way to enlarge the slide back.

This makes it quite unusable for seminars and for screen sharing. Does anybody have any suggestion? Many thanks!

Best Answer

I'm using Ubuntu 20.04 and evince 3.36.7. I have met the issue.

After searching in evince official repository issues I think the answer is in:

https://gitlab.gnome.org/GNOME/evince/-/issues/1486

https://gitlab.gnome.org/GNOME/evince/-/issues/1504


Basically, the issue is introduced when fixing an issue on Wayland but forgetting to limit the fix to Wayland. You should either use Wayland protocol, or use a newer version of envice (you can install the newer version from snap, flathub, etc). For example, use evince from snap: 
sudo snap install evince
