Is wayland being used in a linux vm using kde wayland if the host is running xorg

[tckosvic]

As the title says, am I really using wayland in the kde desktop of a linux vm when the host is running xorg on the real hardware. I run leap 15.5 as a host and have tumbleweed in a vm. libvirt/qemu vm is being used to run the guest.

If so, is this a test of whether or not the host computer hardware could satisfactorily run wayland?

Unless you’re doing GPU passthough, then no, it’s not a test of the hardware, because the video hardware is emulated.

Explain what you understand with “really using wayland”. Either you run X11 session or you run Wayland session. What makes it more or less real?

@tckosvic

I am not sure what it means either. Wayland or X11 - you need to display graphic. Wayland and X11 are using mostly the same components to do it. So what specific hardware requirements must be satisfied for Wayland?

[tckosvic]

I guess I need to simplify my question to satisfy some people. My host machine is running Xorg due to possible conflicts with nvidia graphics hardwaree/software. An installed guest linux vm says it is running kde plasma wayland desktop.

Is the vm running wayland while the host is running xorg?

If the wayland desktop vm runs, is this a valid test of whether the host could run wayland?

A virtual machine (ala VirtualBox or VMware) is a virtualized set of hardware. So yes, the VM can run Wayland while the host is running Xorg.

And if Wayland runs in the VM, that’s not guarantee that it can run on the host.

For example, I use a Wacom Intuos 4 tablet with my Linux host.

The driver for the mouse that’s included with that tablet does some weird things with the scroll wheel, and the developer says that the applications (in this case, GNOME or KDE) need to interpret the events correctly, and they don’t, so the scroll wheel works inconsistently in QT or GTK apps.

In a VM, though, the mouse hardware is virtualized, and the inputs are translated into the correct signals, so the scroll wheel works just fine inside a VM for all applications, even though it doesn’t work in the host properly for all applications.
