Black screen recorded in Ubuntu 17.10

[davidpodhola]

I think it is related to this bug report. Audio is recorded correctly, also mouse movements work.

A side note - when using Ubuntu on XOrg, the capture works better (the video if recorded in raw AVI is still not usable due to quality issues; WebM works fine).

I'm on ubuntu 17.10 and I'm not seeing this behavior. Didn't try sound but video definitely works for me.

Sorry, found out it happening on Wayland only. Wayland is the new default on 17.10, change from 17.04.

Yea, this is a Wayland issue because the compositor won't let any application see the entire screen context. But I'm not sure if there are APIs in place yet to allow applications to get around that (with user permissions).

Same problem as well. Just the cursor moving on a black canvas.

Edit: This issue isn't necessarily confined to Kazam. SimpleScreenRecorder faces the same issue. Green Recorder once worked, but now it is archived. GNOME 3 does have a built-in screen recorder that you can use as written here.

There're several problems with Wayland + Gnome 3+

• Wayland doesn't let you bind global keyboard shortcuts

• Gnome 3 has removed App indicator icons. You will need gnome-shell-extension-appindicator and enable it.

• Wayland can't capture screens the old way, it needs to use gstreamer's pipewiresrc which uses org.freedesktop.portal.ScreenCast

org.freedesktop.portal.ScreenCast is missing in Ubuntu 20 which is on an old version of xdg-desktop-portal...

It is in Ubuntu 21.

I have a brand new laptop. When I used Wayland, and it went into power saving mode, the screen flashed fuzzy with static. Looks like a work in progress.
