Hello,
I keep seeing this message on my openSUSE Tumbleweed console after recent updates:
ERROR: ld.so: object ‘/usr/NX/lib/libnxegl.so’ from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.
This is what I see on Terminal (in case file is corrupt etc)
ilgaz@think:~> ls -l /usr/NX/lib/libnxegl.so
-rwxr-xr-x 1 root root 54504 Jul 12 11:18 /usr/NX/lib/libnxegl.so

October 7, 2024 at 11:41 #50015fajny.masz.tornisterParticipantMy version is: nomachine-8.14.2-1.x86_64 on RHEL 8.10 and i keep getting it on every application installed with snap.

October 10, 2024 at 17:20 #50112BritgirlKeymasterFajny, is it possible that you have installed a 64-bit package on a 32-bit system? This could explain why the library cannot be loaded.
October 11, 2024 at 21:14 #50168amprince01ParticipantI’m receiving this error since upgrading to 8.14.2 on OpenSUSE Tumbleweed. I did the upgrade through the application when it prompted me to.
ERROR: ld.so: object ‘/usr/NX/lib/libnxegl.so’ from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.
ERROR: ld.so: object ‘/usr/NX/lib/libnxegl.so’ from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.Free Version 8.14.2 – upgraded from 8.13 – the error comes up when I run commands in bash.
October 12, 2024 at 15:38 #50177asp100mParticipantApparmor probably blocked the shared object.
You need to allow it by Yast -> AppArmor -> Scan Audit Logs.
In my case, it was lessopen.sh called by less.October 14, 2024 at 18:25 #50225hawkParticipantHello Ilgaz, fajny.masz.tornister and amprince01
May i ask you for more information?
– please share example snap app that is causing the problem?
– are you connecting to a headless environment?
– which graphical shell you are using?
Logs from /usr/NX/var/log/ directory and output from commandenv | grep -i nx
may be very useful. Send those information to forum[at]nomachine[dot]com, please.October 15, 2024 at 10:25 #50227hawkParticipantOne more thing. Some useful information about things blocked by apparmor can be stored in journalctl. Please run
sudo journalctl -g apparmor > apparmor.log
command, collectapparmor.log
and send it to forum[at]nomachine[dot]com along with other informations.October 15, 2024 at 14:20 #50229JumpingmanjimParticipantI get this error too on Ubuntu. Please fix it.
October 17, 2024 at 11:59 #50284hawkParticipantHello Jumpingmanjim,
May i ask you to share some information i asked above?
– please share example snap app that is causing the problem.
– are you connecting to a headless environment?
– which graphical shell you are using?Also i will be grateful if you send us nx_journal.log from command
sudo journalctl > nx_journal.log
. Send those information to forum[at]nomachine[dot]com, please.October 17, 2024 at 14:38 #50289amprince01Participant- I get this error when I do something like run
sudo zypper ref
or just about anything from the command line. - I am connecting to a laptop that is open, the screen is up – it actually doesn’t matter, I get the error with the screen off as well.
- I’m using KDE6 Plasma v 6.1.5 running on X11 with OpenSUSE Tumbleweed-Slowroll 20241002.
- One thing that I find interesting and might be useful to you is that I’m running NoMachine on 2 other systems. All of them the same same OS and all using Plasma (one is Wayland and the other is X11). I do NOT have the problem on either of them. The difference is that the system having trouble is one that has had NoMachine upgraded a couple times.
- I suspect that you’re looking at a regression of some sort.
- I’m sending the journalctl and nx logs as requested and the command
- alisia@alisia-p14s:~> env | grep -i nx
- LD_PRELOAD=/usr/NX/lib/libnxegl.so
October 23, 2024 at 18:51 #50370amprince01ParticipantIs there any update on this issue? It’s really annoying when this happens since I spend a lot of time in the command line on this computer.
October 24, 2024 at 22:05 #50401hawkParticipantWe are still investigating this issue.
Are you using this machine as a headless environment, running it in NoMachine virtual
desktop session or some other remote method or you are connecting to a physical session?If you are not connecting to the physical display with Wayland enabled you can try disabling EGL
capture by commandsudo /etc/NX/nxserver --eglcapture no
and getting rid of LD_PRELOAD env by commandunset LD_PRELOAD
Thank you for your patience.
October 30, 2024 at 09:52 #50504fajny.masz.tornisterParticipantLD_PRELOAD mechanism is simply prohibited on some laptops//computers by policy ( corpo machines or other junk hadrware with corpo policy ) so this is the case when on regular ( policy-protected ) user ( not root/Admin ) the LD_PRELOAD is … forbidden which triggers som “kill” + “reporting” switches and get’s blocked.
Not the best idea / approach, with the LD_PRELOAD ( also got to witness the LD_PRELOAD bocking idea on AIX.. bt this is just a remark not a NoMachine observable ).
I stopped having the env LD_PRELOAD being set ( i use on laptop standard X ) so … problem gone.
October 30, 2024 at 12:03 #50516IlgazParticipantI bet Terminal guys knows a trick however, it becomes completely unbearable with ‘distrobox guest distribution shell’ as the message is being repeated tens of times.
