After upgrading to Ubuntu 17.10 I noticed some of my screencasting applications are not working, for example screencasting tools like SimpleScreenRecorder and vokoscreen. (link)

Also I noticed features like screenshot from GIMP is not working properly, producing blank screenshots (link). Shutter too is producing glitchy screenshots (link).

Why is this happening and how do I fix this?

Ubuntu 17.10 by default lets users log in to a GNOME environment on a Wayland session. Applications which are not compatible with Wayland yet run under a XWayland compatibility layer.

But advanced applications, which depend on and/or control X11 server "too much" (screen-capturing/recording etc.), might fail to run in a Wayland session.

As a workaround you may try to switch back to an Xorg session.

    What does one loose by running an Xorg session and not a Wayland session? – Masroor Oct 20 '17 at 17:18

    @Masroor This is a very good read. tl;dr: X is a legacy technology with many flaws and holes, but then again Wayland is not that much supported. – pomsky Oct 20 '17 at 17:24

    @pomsky No, the screenshot feature does not work once I switch back to Wayland. – Masroor Oct 21 '17 at 1:34

    @Masroor If you have a hidpi display, then Wayland is a much better choice. In general Wayland handles hidpi displays in a much more smooth way, and only Wayland supports the scenario that one of your monitors is hidpi and the other one is not. On Xorg scaled/hidpi is all in or all out. – Attila Fulop Oct 31 '17 at 8:45

Try Green Recorder. It supports Wayland & Xorg and it will work with Ubuntu 17.10. For installation instructions please check this link

Open terminal and run all the below commands one by one

sudo add-apt-repository ppa:fossproject/ppa
sudo apt update
sudo apt install green-recorder
green-recorder
