We checked Fedora 23 with Cinnamon in our labs and we didn’t come across these problems you’ve described. Can you make short video with that flicker issue? Please also run debug, restart nxserver (
sudo /usr/NX/bin/nxserver --restart) reproduce problem, collect logs from the server side and send them to forum[at]nomachine[dot]com? Send also nxplayer logs (it’s R-* directory which is located in the /home/.nx/ on client side). Instructions about debug and collecting logs you can find there: https://www.nomachine.com/DT07M00098#1.We still haven’t been able to reproduce the problem. Please send also output of those commands:
ping -c2 localhost nslookup localhostWe weren’t able to reproduce problem. What is your desktop environment? Please enable debug, restart nxserver (
sudo /usr/NX/bin/nxserver --restart). If the problem appears again, collect logs and send them to forum[at]nomachine[dot]com. Please send also node.cfg and server.cfg which you can find in/usr/NX/etc/directory.Instructions about debug and collecting logs you can find there: https://www.nomachine.com/DT07M00098.
You need to have administrator rights to collect logs.
I can create a .zip or .7z file. Please confirm either of these okay.
Yes, both are ok.
Please try the tip suggested by graywolf from https://forums.nomachine.com/topic/ubuntu-16-04-headless-resolution-stuck-1024×768.
If you want use the machine as headless all the time, you can turn off lightdm service on system start:
sudo systemctl disable lightdmCan you check if changes in the /boot/config.txt still appear after a reboot? If not, please change values again and afterwards save file, then execute command
sync. Finally, reboot machine.1. change file
2. save file
3. sync
4. rebootIf that doesn’t help – try upgrading your system.
Thanks for the report. If UPnP doesn’t work it remains to configure port forwarding manually. Instructions you can find on article https://www.nomachine.com/AR11L00827. Check section “IMPORTANT”.
Did you try execute
<code>sudo /usr/NX/bin/nxserver --upnpmapcommand? It should list your external IP and Port in the line: “NX port 4000 mapped to”. If there is no IP please write here your router model so we can investigate the problem. In that case you’d need to configure port forwarding manually to connect there from external network.Thanks for the output. It looks that there is some routing problems. Can you send also file with routing output?
sudo iptables -t nat -L -n -v > routing_output.txtTo change resolution on Raspberry Pi edit /boot/config.txt and replace lines:
#hdmi_group=2 #hdmi_mode=35to:
hdmi_group=2 hdmi_mode=85After that save file and reboot system.
About those commands. First – installs lubuntu environment, second uninstalls Unity DE, that third one completely removes NoMachine from system. Did you install again NoMachine?
Open a terminal and execute commands:
sudo apt-get install --reinstall lubuntu-desktop sudo apt-get autoremove --purge ubuntu-desktopFirst one is to install and switch to lubuntu, second one is to remove Unity desktop environment. To avoid having to set the NoMachine configuration files, the best thing to do is to remove NoMachine completely (
sudo dpkg --purge nomachine && sudo rm -rf /usr/NX /etc/NX) and reinstall it.Please enable debug on server side and restart nxserver. If you were able to reproduce problem collect all logs (nxclient from %USERPROFILE%\.nx and nxserver from %PROGRAMDATA%/NoMachine/var/log) from server side and nxplayer logs (/home/<username>/.nx) from client side. Please send them to forum[at]nomachine[dot]com.
More instructions about debug and collecting logs you can find there: https://www.nomachine.com/DT07M00098#3.
If your router support UPnP please enable it in the NoMachine server configuration file. To do it set key “EnableUPnP NX” in the /usr/NX/etc/server.cfg and execute command
sudo /usr/NX/bin/nxserver --upnpmap(more info you can find there: https://www.nomachine.com/AR11L00827).
