This is actually fantastic news!

Hi,

it certainly doesn’t work for us with an Intel ARC 380* on a recent Fedora 39.

Br,

(*) And UHD Graphics P630

[timo]

For the Intel UHD P630 machine

$ ls -l /dev/dri/
total 0
drwxr-xr-x. 2 root root         80 Jun 13 21:31 by-path
crw-rw—-+ 1 root video  226,   1 Jun 13 21:31 card1
crw-rw-rw-. 1 root render 226, 128 Jun  9 18:43 renderD128

The server housing the Intel Arc 380 (DG2)

/dev/dri

did not exist there.
I guess, that’s why you were asking.

Reason is the terrible Intel Arc that behaves erratic on boot.
A power cycle solved that.
(We have two of them, that behave identical. And you can find
plenty of bug reports of that sort. So it’s certainly not a hardware error.)
For that matter I suggested to focus debugging on the P630 first
as it also fails for encoding but doesn’t come with the additional
woes of the Intel Arc (on Linux).

I’ll send you the logs for the DG2 properly initialized.

Unfortunately, placing anything on the jumphost server is out of question in our case for various reason.

[timo]

Hi,

thanks for your answer.

To my best knowledge our topology does not provide a HTTP or SOCKS5 proxy.

We need to go the way opening a tunnel on a jumphost to the remote target like

ssh user@jumphost -L [forwardport]:remotetarget:22

and then connect via SSH protocol to localhost:[forwardport].

That works but including the jumphost-connection directly into
the client would definitely ease the use a lot for our coworkers.
(Even more helpful on client platforms like Android)

Br,
Timo

Found the time to compare against the WQHD setup.

Seems like this has to do with scaling on HiDPI setups.
The default puts the NM client window to a geometry of said 1280 x 720 px.
Consequently, syncing the server’s desktop res fails to up that and provides just that.
Fonts are visibly washed out, whereas on the WQHD it’s crisp.

There are plenty of threads and help topics about that.
Yet, all application specific steps I tried did not help.

Only option that seems to have an effect for me at all is that one

Then again everything gets very small.
Up the scaling on the client does not help as it only allows going
from 300 % (auto for that res) to 350 % max, besides being a global setting.

Changing dpi on the server (Fedora 38, GNOME 4) came to my mind,
but that ended up in a non-working state where the mapping from mouse to screen space
seems to be off. (Wasn’t able to click buttons and fields anymore straightforward).

Can someone confirm this on a Windows 11 UHD (4K) setup?
Wonder if that’s only to do with the res (or better the actual dpi from the panel “driver”)
or if that’s also dependent on the GPU driver, etc …

As a workaround I’m now switching the display to FHD.
But even than it only works with additionally setting the compat dialog as posted above.

Hi,

in case it may be relevant (changelog gave no hints in that regard though),
I updated the server (and client) to 8.5.3 but the issue still persists as decribed.

[timo]

Thanks for your help!

I sent you the new logs.

All packages are from the official Fedora repositories.

Following your hints I also had to link

libva-drm.so -> libva-drm.so.2

Unfortunately, it still doesn’t work and now claims

N.B. The same environment with an Intel ARC 380 shows the message.

Thanks for your help.

Thanks for your help.

Yes, will give it a try asap.

[timo]

Hello,

any news on that one?

Thanks for your help.

[timo]

Hello,

did you receive the mail with the logs attached?
If there is anything missing, please let me know.

[timo]

Thanks for the reply.

So I set

‘AgentX11VectorGraphics 0’

restarted the server and reconnected the client.

Checking the Server-GUI seems to tell me that X11 vector graphics is not enabled.

But I still get “SW encoding” on the client.

Where do I have to look for further information?
