I don't know about GNOME dealing with it. But if they have that
doesn't change the fact
that KDE/sddm hasn't done so successfully.
So, if this is a need why don't you switch to using gdm and then look
into the same question
from that angle.
I'll try gdm and see what happens.
I don't have a use case from switching users as our cats hardly
demand computer time.
And, if I want to run GNOME for some reason (or another DE) I'm
content to do so in a VM.
I have a very specific use case which I doubt would be of much interest
to most people. Certain Wine-based software (yes, games) runs well
under Gnome but in KDE/Qt the whole login session can completely freeze
at random times. To avoid this, I log out of KDE and into Gnome (both
under X11) to run these apps, but this messes with my session settings
every time, e.g. every tab I'm logged into under Chrome is reset (I
assume something is moving cookies around), not to mention screen
layout, window sizes etc. It's a major pain.
My plan is to do the Wine stuff as a completely separate user, but it
would be nice to be able to switch back and forth without all the
logging in and and out. Call me lazy.
While network interfaces are designed to be shared it doesn't
mean
harmony exists between
users. Or that the secondary user is the same person. Secondary
user comes home and
without thinking fires up a VPN connection unaware they are
disrupting a long file transfer.
It is (in theory) possible to separate users by means of network
namespaces, and even run some transfers in a VPN while the rest are in
the clear, even in the same user session. Not that I've ever managed to
get this to work ...
