    I’ve installed new Debian 9 on my Raspberry Pi and the latest NoMachine after that. At the first moment everything worked fine but after reboot I am able to connect on remote desktop only with a small resolution size, 720×480 (I think) instead of preferred 1280×720. Couldn’t find anything in internet and that’s the reason why I am writing here.

    Can someone help to resolve this problem?

    Just to add, changes of resolution through default RPi configuration manager don’t change anything. This is something related with NoMachine settings.

    We’re not able to reproduce this issue. From a terminal on the Raspberry host can you give us the output of :

    grep -E “hdmi_group|hdmi_mode” /boot/config.txt

    Logs from the connecting client will be useful. You should follow the instructions for the client side here https://www.nomachine.com/DT07M00098  and then submit them to forum[at]nomachine[dot]com.

    From the Raspberry we’d need a tar of /usr/NX/var/log directory.

    Here there are config.txt and /usr/NX/var/log archives.

    To change resolution on Raspberry Pi edit /boot/config.txt and replace  lines:

    #hdmi_group=2
    #hdmi_mode=35

    to:

    hdmi_group=2
    hdmi_mode=85

    After that save file and reboot system.

    Can 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. reboot

    If that doesn’t help – try upgrading your system.

    I did all of that but it didn’t work.

    Fortunately, everything started to work properly after playing with raspi-config utility. I’m not sure what I did there to force NoMachine to work normally but now it works 🙂
