Keep getting message on console regarding LD_PRELOAD failure

[cppgent0]

Product: NoMachine
Version: 8.1.2
Platform: Linux

(PS you might want to make the NoMachine panel that has this info copy-n-paste compatible, instead of me typing it)

On Ubuntu 22.04. This machine has the server on it, but I only use it as the client.

Getting the same warning. So I tried the command as suggested:

sudo /etc/NX/nxserver –eglcapture no
NX> 900 EnableEGLCapture key set to: 0.
NX> 900 Disabled EGL screen capture in ‘/usr/share/applications/org.gnome.Shell.desktop’.
NX> 900 Disabled EGL screen capture in ‘/usr/lib/systemd/user/org.gnome.Shell@wayland.service’.
exit

restarted the terminal and get the same warnings again.

But if I keep the terminal up and open another tab or terminal window, it works fine. As soon as I close all the terminals, then the issue comes back.

I don’t have ld.so.preload:

ls /etc/ld.so.preload
ls: cannot access ‘/etc/ld.so.preload’: No such file or directory

but there are files in /etc/ld.so.conf.d none of which look like they’re related to NoMachine

$ ls  /etc/ld.so.conf.d/*
/etc/ld.so.conf.d/fakeroot-x86_64-linux-gnu.conf
/etc/ld.so.conf.d/i386-linux-gnu.conf
/etc/ld.so.conf.d/libc.conf
/etc/ld.so.conf.d/skype.conf
/etc/ld.so.conf.d/x86_64-linux-gnu.conf
/etc/ld.so.conf.d/zz_i386-biarch-compat.conf

The “unset LD_PRELOAD” works. I can put in the .bashrc to make it permanent.

Well, sort of works.

If you put the unset at the bottom of the .bashrc, I still get a few warnings when I start the first terminal. But if I put it at the top of the .bashrc then I only get one warning.

We will. Thanks for the suggestion for improvement.

You mentioned “restarted the terminal and get the same warnings again.” Restart is not enough. You need to reboot. If you disable eglcapture and reboot, then “unset LD_PRELOAD” is not needed.

Reboot worked, thanks!

On Ubuntu, not used to rebooting 🙂

(PS the original post didn’t mention the reboot, at least I don’t see a mention of it.)

Yes, you are right, this was not made clear earlier. I’m glad everything is working now 🙂

I use openSUSE Tumbleweed…

I tried to look at AppArmor and generate logs via:

journalctl -g apparmor > apparmor.log

But latest message was logged 2 days ago.

So either it is not logged or it is not related to AppArmor.

maxim-nomachine, can you send us the server-side logs so we can check them? You can extract them using the instructions here: https://kb.nomachine.com/DT07S00243. Send them to forum[at]nomachine[dot]com. Please use the title of this topic as the subject of your email. Thanks!
