Post by candycanearter07Wait, what's a 3D desktop?
To some extent, this started with the introduction of Compiz.
On Knoppix, Compiz started out as a series of garish animations
for desktop activities.
But Compiz also became part of the switch to compositing
and caching window renders, and doing Z-axis priority to
establish the current desktop view.
All platforms now have compositing. Apple had it. Windows
changed from Expose Events to Compositing. And Linux got it
too.
It was just easier to do some of these things in OpenGL
(like the strange Compiz animations that actually involved transforms
as part of their execution).
Things like Libreoffice use OpenGL "even when they don't need to".
LibreOffice uses OpenGL on both Linux and Windows (it does not use
DirectX or have the software for DirectX). So if a transport
layer in the graphics stack was not "prepared for 3D", then
perhaps a Linux LibreOffice window would remain blank in RDP Windows.
Terminal Server in Windows, has extensive graphics capability.
WSL/WSLg in Windows, in a matter of a couple weeks, they
tuned a Linux VM, made the graphics travel through Terminal
Server (potentially, RDP), and make it responsive and
glitch free in a short time. The path your graphics take
in that environment, that's a *huge* stack.
On a daily basis, on Windows 11, I run a Linux version of
Firefox on the same desktop. In the Task Bar, is a Firefox
icon... with a tiny Penguin drawn in the lower right corner
of the icon. That's my Linux Firefox. It means I can run a
crusty older Firefox in Windows (to annoy advertisers), and
a "compatible supported" Firefox, using WSL/WSLg. And the
graphics burble up through a Terminal Services stack of some
sort.

Any time the term "RDP" comes up, you just know there
will be misery and hair loss :-) Part of the problem with the
general topic area, is different SKUs of Windows may have
different capabilities.
On the Linux side, you start with a review of an Arch article,
to get the general gist of the thing.
https://wiki.archlinux.org/title/xrdp
"3.3 Graphical acceleration
For Xorg sessions, you can enable OpenGL and Vulkan graphical acceleration
by installing xorgxrdp-glamor for Intel and AMD GPUs and xorgxrdp-nvidia
for Nvidia GPUs."
And maybe in that suggestion, you would have used Driver Manager to
switch from Nouveau to NVidia driver, if that had not been done already.
When they "name" GPUs that way, you probably want to start with the
right graphics base, so the other shit bolts on top. When it comes time
to Upgrade your Mint to the next version, you might switch the driver
back to Nouveau temporarily (if that's how it arrived when installed)
-- and when you're doing the Upgrade, you'll be doing
that while seated in front of that PC. No doing that over RDP :-(
You can't have fun, unless it's complicated. Or so I've heard.
