the name of the Wayland location I would have to look it up on the

KDE to auto-scale like Gnome does, I found a bug report that someone
raised for scaling issues in F34 and I thought they were saying that
the Wayland support in KDE was not stable, is that still the case?):

I use kvm for my VMs and this is what I get with a default workstation
install. I'm using the virtio display option in qemu. I've attached
a screenshot of the default list of resolutions that Gnome has. I
don't have a 4K display, but all the standard resolutions are included
anyway. I can pick the display size and the VM resizes, with
scrollbars if necessary.
But if I turn on the "auto-resize VM with window" option, then
whenever I resize the VM window or go full-screen, Gnome will switch
to the resolution to fit it exactly without scrollbars. This works for
both the virtio and QXL display options, but not VGA. So the problem
is just with vmware and virtualbox not properly communicating the
screen size changes to the VM.
The problem I have is Gnome scales when the windows size changes, but
KDE does not, which is why I put the modelines in the conf file, and
then KDE does scale.
How did you you get the monitor-get-edid to work, when I switch to root
with "sudo su -" and issue the command I get access denied, have I done
something wrong?

Steve
