I have an Alma linux 9.5 (Gnome 40.4) VM running in Hyper-V

Because clipboard support is ropey using Hyper-V console, I've
configured Screen Sharing from Gnome Settings, and opened firewalld for vnc-server on tcp/5500. I see the tcp port listening, I see thefirewall alloewing connections.

I've tried three VNC viewers (tight, real and ultra) none of them can
agree "security types" to get a working connection.

I've tried disabling encryption using
gsettings set org.gnome.desktop.remote-desktop.vnc encryption "['none']"

Still no go, I'd rather not setup a whole vnc-server and dick about with launching new X/wayland/xRDP sessions, just stealing/sharing the GUI
session from the console would suit me best.

Any suggestions that just work?

I'm using Ubuntu 24.10, Gnome-47, wayland. RDP works. However, I think
this is a recent thing. So probably not applicable to you.

In the past, I've used NoMachine, which I don't like as much as RDP, but
it is useable.

Yes, I don't think Gnome 40 supports RDP, it would suit me, but I'd
rather stick with something centos'ish rather than fedora'ish.

Alternatively Ubuntu LTS 25.04 later this week?

I don't see how Gnome has managed to apparently support only one
security type (18) that no VNC client supports, and not even a way of
ignoring security?

You might want to try Remmina, so far this has worked on everything I
use.

Thanks for the suggestion, to run it on Windows appears to require
running it under WSL, which I could handle, but might be a little too Inception'ish for other people ...

Reading a bit, it is actually FreeRDP, which lists Gnome 42 as the first version offering support.

Centos is dead, isn't it? I think you need to move to a newer distro.

Surely moving to Debian is a bigger step than a new Red Hat distro. I
like my comfy slippers as much as the next old man, but even I will
switch between Debian distros.

Yeah, what can I say, whenever I've tried VNC, it has been shit. That's
why I used TeamViewer and then NoMachine.

Yeah, I use Remmina as my Linux RDP client. It is OK. Not quite like MS
Windows RDP client, but not far off.

That's why I said centos'ish I'm actually using Alma, there's also Rocky.

I've used Ubuntu where I "have" to, but I feel slightly fish
out-of-water compared to something redhat'ish. I'll check how RDP
works using a test Fedora VM.

Yeah, you need to bear in mind the foibles of VNC clients, but they're
usually usable.

I now have a Fedora41 VM for testing (also using gnome47 and wayland)

it needed some minor dicking about with /etc/xrpd/xrdp.ini

RDP works from the standard mstsc.exe client on the server that's
hosting the fedora VM

clipboard works both ways (for text at least)

after adjusting for hi-DPI scaling, very readable

vi in a terminal session is oddly s t r e t c h e d out and cursor is
almost off-by-one column

I'm using nested RDP (win11->winsvr25->linux) but seems responsive
enough, it's eating quite a bit of CPU though, perhaps the scrape
intervals need tweaking?
h264_frame_interval=16
rfx_frame_interval=32
normal_frame_interval=40

Wild guess would be font, possibly locale related, local machine remote
machine mismatch. e.g. C.UTF-8, GB_UFT8. Not remote desktop per se. But
that is just a wild guess.

Yeah, I dunno, I only do very occasional stuff into a Linux RDP server.
Mainly an old PC I repurposed as a Linux backup file server. I don't
care much about performance.

Mainly, I use RDP into a remote Windows PC from a Linux client.

Ahhh, 25.04 was released, but I was wrong about it being an LTS version.
