A screenshot showing screen sharing dialog in Microsoft Edge Browser
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
STEPS TO REPRODUCE
1. Run a screensharing program (Google Meet on Microsoft Edge Browser in my
case)
2. Trigger screen sharing, choosing "Entire Screen" to share
OBSERVED RESULT
The physical screen can be shared.
However, the "New Virtual Output" option isn't usable.
EXPECTED RESULT
KDE's virtual desktop should be able to be shared in screen sharing picker.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: openSUSE Tumbleweed 20240209
(available in About System)
KDE Plasma Version: 5.27.10
KDE Frameworks Version: 5.114.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
Currently, in browsers, when triggering screen sharing, the choice is between
sharing tabs, a window and Entire Screen (a single display in multi-monitor
setup).
However, I observed that my peers who are working on Macs are able to screen
share one of their virtual desktops. That is, they have one physical screen
with multiple virtual desktop, where the “screen” being shared is actually
**one of the virtual desktops**. This is great when we need to show more than
one window in online meetings (a virtual desktop), but not everything that can
be seen in our physical screen (especially when working with only one physical
display).
As virtual desktops exist in KDE, both under x11 and wayland, I think it would
be great if we can share the **virtual desktop** as a screen.
The “New Virtual Output” in KDE Portal on wayland only create a new virtual
output that seems to pipe directly into the browser screen share, where I
cannot see the screen at all. This is of course, not usable. (I actually wonder
what exactly is the use case for this virtual output).
So my feature suggestion would be to allow each **virtual desktop** as a
sharable screen in Portal screen picker. Of course the naming of the screen
should be clear to distinguish sharing an actual screen (ie “Laptop Screen”)
versus a virtual desktop (ie, “Desktop 2 on Laptop Screen”). And maybe, an
option in KDE Settings on Virtual Desktop on whether to allow virtual desktop
as sharable screen/device.
I created a KDE Discuss forum post
(https://discuss.kde.org/t/screen-sharing-support-for-kdes-virtual-desktop/6680)
discussing this that hasn't gained much attention.
