After uninstall, all programs look for /usr/NX/lib/libnxegl.so

[dabe]

I installed NoMachine for my Fedora 38 computer. I was faced with this issue https://kb.nomachine.com/TR05U10874 on many of my Flatpaks, which was a deal-breaker for me since I use so many Flatpaks. I uninstalled NoMachine following this instruction: https://kb.nomachine.com/DT07M00078#4, and then I removed the /usr/NX directory, assuming I wouldn’t need those libraries anymore.

Now, literally anything I do on my computer throws this error, sometimes several times:
ERROR: ld.so: object '/usr/NX/lib/libnxegl.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

I believe it is causing some other unexpected issues, as well.

I mean, just look at this short terminal session output:

Where did NoMachine start setting the LD_PRELOAD variable, and how do I make it stop setting it?

[Britgirl]

Maybe you didn’t uninstall NoMachine as expected (as in the guide). You just removed /usr/NX directory which is not the correct way. If you do that our uninstall scripts can’t clean the system. Do the following:

1) sudo rm -rf /usr/NX /etc/NX /var/NX
2) install NoMachine by rpm -i nomachine….rpm
3) uninstall NoMachine by rpm -e nomachine…..
