Hi,
hardware decoding is always enabled by default on Mac. If you send the logs, we can check what is actually used. You can find instructions in https://www.nomachine.com/DT10O00163#2 and then you can send them to forum[at]nomachine[dot]com. I would also check CPU usage on both the client and the server during those freezes.
Hi all,
the issue was reproduced in our labs and it is tracked here:
https://www.nomachine.com/TR06R09772
The fix will be made available in the next software update. You can also select to be notified when the Trouble Report is closed.
At the moment, as a workaround, I suggest to use the H.264 codec (which is anyway the recommended option).
I’m glad to hear that your issue is fixed. Of course it is always recommended to upgrade to the latest version in case any problem is found.
The latest version is what caused the problem.
Do you mean latest 6.11.2 or any version before that?
If the issue is present with version 6.11.2, would you try to reproduce again and send us the logs for debugging? You can find instructions in https://www.nomachine.com/AR10K00697 (for server side logs) and https://www.nomachine.com/DT10O00163#2 (client side). You can send everything to forum[at]nomachine[dot]com.
Is the remote computer “headless” (i.e. has no monitor attached)? Or, in case it is a laptop, is the lid closed?
In case, can you try to attach a monitor, or leave the lid open, and check again?
Hi,
is the server a Windows machine in your case? What version? Is it maybe a headless machine (no monitor attached), or has it the lid closed (in case it is a laptop)?
Would you mind sending server side logs from a problematic case, as explained in https://www.nomachine.com/AR10K00697?
Hi Zenith,
the fact that you don’t see glitches on the TV doesn’t rule out a problem with drivers. Rendering (pushing) to the GPU may work correctly, but pulling the screen content back from the video memory may not. Unfortunately this is not something that NoMachine can control.
It looks like libnvidia-encode.so can’t be loaded. The possible cause is that /usr/lib/x86_64-linux-gnu/nvidia/current/ is not in the library search path. You could try to create a symlink to that library:
sudo ln -s /usr/lib/x86_64-linux-gnu/nvidia/current/libnvidia-encode.so /usr/lib/x86_64-linux-gnu/libnvidia-encode.soIf that won’t work, please try to check permissions for that library and other libraries linked to this one (you can find such linked libraries with the ‘ldd libnvidia-encode.so’ command).
Hi,
unfortunately there is nothing more that can be done in the NoMachine software. After excluding hardware encoding, GPU is not used by NoMachine directly. I have seen other similar cases where the local X server is slow to pull pixels data back from video memory. This is an issue on the video card/drivers side. You may try to use a different version of the drivers, but I can’t say if that will solve the problem.
Hi,
do you have maybe the monitor detached from the server, or is the lid closed (in case you have a laptop)?
Hello,
please run this command and show the output:
sudo find / -name libnvidia-encode.so -or -name libcuda.so 2>/dev/nullHi,
in some cases, even if the machine is headless, the GPU could be “turned off” if the monitor is switched off. Can this be the case? If so, could you try to switch on the monitor attached to the server and check again?
Also, to narrow things down, you can try to disable hardware encoding in NoMachine (‘EnableHardwareEncoding 0’ in /usr/NX/etc/node.cfg) and see if you still experience worse performance on Nvidia than on Intel.
