[winswitch] [ANNOUNCE] Xpra LTS 3.1.4 : many accumulated fixes

Tue Mar 7 17:48:02 GMT 2023

Hello.

I would like to integrate Ubuntu,Fedora,Arch or maybe some other distro
into one single,homogeneous and flexible operating (OS) context. I would
like to use Ubuntu (22.04) as the host OS and the rest of the OSes
(Fedora,Arch) will be virtualized within different virtual machines (I
don't want to use containers,I know that they are a better choice,but I
want to understand if a virtual machine is good anyway when it is very well
configured). The idea is also to use qemu + kvm with the nographic and no
vga options enabled,without virt-manager or boxes. I don't want to open and
close the virtual machine graphical interface every time I want to run an
application. I find it much more comfortable if I can run every application
and command within one only terminal by premising,for example,a letter
indicating to which distribution the command or application belongs to. Or
I could tell xpra to open the fedora or the arch linux terminal. For sure
it will be much faster to configure,but it has less scenic effect.

So. I've installed Fedora 37 on a qemu-kvm VM and I've installed xpra on
Ubuntu and on Fedora. As you can see below,when I invoke firefox from the
Fedora VM (that has IP = 192.168.122.156),it starts correctly :

ziomario at Z390-AORUS-PRO-DEST:~$ xpra start ssh://marietto@192.168.122.156
--start=firefox

The problem is that firefox takes 6 or more seconds to appear. And it's not
the only one that's so slow. Every application that I try to run is very
slow. You can imagine that is not good if I want to  integrate
Ubuntu,Fedora,Arch or maybe some other distro into one single,homogeneous
and flexible operating (OS) context. When I want to run an application, I
expect it to start as fast as it would if it were installed locally. Is
that goal achievable ?
