I’m trying to determine if hardware accelerated encoding is in use on my machine. The hardware supports it, and I am getting an h.624 connection, but the CPU use in htop seems a bit high to me. The posts that I’ve found from a few years ago about this refer to log files that no longer appear to be written in the current versions.
It is enabled in my settings, but there’s no indicator that it’s actually in use.
So, how can I check this now?
Thank you!February 22, 2021 at 16:49 #32106
On the Linux server you can also check the session files in /usr/NX/var/log/node/C-*
As well you can check by executing:
grep -i encod /usr/NX/var/log/node/C-*/sessionFebruary 22, 2021 at 20:49 #32107
Please check this new feature implemented in the version 7 https://www.nomachine.com/FR04R03973.February 23, 2021 at 09:02 #32108
That’s actually what I was referring to when I found old posts mentioning a way to check. Maybe I don’t have the logging enabled for that, but I don’t have a node subdirectory in /usr/NX/var/log. Since the posts were a few years old, I started thinking that the log information was moved elsewhere, but none of the files in the log directory has anything like that. On my install, the only subdirs off that are “archives” and “logrotate”.
I did find that post you linked as well. So, one thing about that particular item, it doesn’t say where in the UI that information is located. My server version is 7.1.3 but I’ve just noticed that I think my client is rather outdated (it was kind of tricky to find something that showed the client version, at least on Windows). If my older client (I think it’s 6.4.6) is able to display the string properly, than I am on all software, which I’ll have to figure out. I’ll update my client and see if that changes what I’m seeing in the connection information. I’m assuming I’m looking in the right place (Display Settings on the client; it’s the only place that has a string that looks like the information mentioned in the KB article).

About /usr/NX/var/log/node folder please check on the server side.
About Feature implemented I mentioned in a previous post, you need to update your client to the latest version 7.
Information about used codec will be displayed in Display settings and Connection information.February 24, 2021 at 09:25 #32126
“/usr/NX/var/log/node folder please check on the server side.”
The server doesn’t have it.
jason@CB5:/usr/NX/var/log$ du -a .
I did upgrade my client and I can see the string now, and it is indicating that I’m not getting h.264 acceleration, so I’ll have to figure out why that is.

/usr/NX/var/log/nodefolder please check on the server side.
I finally found the session logs, per https://www.nomachine.com/FR11Q03892
As of version 7.0.208: The display agent log files should be stored in the correspondent session directory created under the home directory of the session owner, e.g. the user’s home/.nx/node/C-display-sessionid directory. Which is where my session logs are.
The session log is verifying (in addition to the client information) that I am getting only the software encoder, though I still have no indication why.

In order to understand why GPU encoding is not in use, can you provide us with following information:
– GPU card on the server side
– GPU drivers used
– Session log fileMarch 3, 2021 at 10:11 #32222

Please can you execute following commands to install debug library:
wget https://download.nomachine.com/44bef5297fe9efb3430b9fd47ad18b01/downloads/temporary/forum/libnxcex.so sudo /etc/NX/nxserver -shutdown sudo mv /usr/NX/lib/libnxcex.so /usr/NX/lib/libnxcex.so.ORI sudo cp -rv libnxcex.so /usr/NX/lib/libnxcex.so sudo /etc/NX/nxserver --startup
After reproducing the problem please send us from server side session log file.March 8, 2021 at 11:28 #32268
Updated session log- I’m already looking to see if I can figure anything out about the obvious problem in the log (failure to load libva.so) but if you have ideas/knowledge already on this, please do let me know!

Ok, I think I may have found the immediate problem:

I don’t appear to actually have anything linked as “libva.so”. I’m not super familiar with the intricacies of libva, so I’m not sure if it’s safe/would fix the issue, to just link libva-drm.so.2.800.0 as libva.so the way it’s currently linked as “libva.so.2”. i.e. not sure if that’s the current version of the same library and also compatible, so insight here would be helpful!
Thanks!March 8, 2021 at 13:47 #32292
can you link following libraries in folder /usr/lib/x86_64-linux-gnu/
ln -s libva.so.2 libva.so ln -s libva-drm.so.2 libva-drm.so
