I configured VNC on my Jetson Nano 2GB (JetPack 4.5.1.) and adjusted Desktop Resolution according to the instruction in the README-vnc. I made a mistake in setting resolution (1920 * 10080 instead of 1920 * 1080) in /etc/lightdm/lightdm.conf.d/50-nvidia.conf (however, everthing worked both on my notebook with VNC and on display attached to J_Nano). After I corrected the resolution and made a reboot, I got this mistake on a display attached to J_Nano, and I can’t get through it.
I can ssh my J_Nano from my notebook (USB device mode) and navigate through directories, but I don’t understand how to fix the error and be able to work again with standalone J-Nano (with display+keyboard+mouse attached).
I have read posts related to similar errors, but could not find relevant solution.
Could anyone help me please to solve this problem?
Thank you for your reply. Actually, I couldn’t start VNC (although I set it up correctly) when I had this mistake. I have recently resolved the issue this way:
As far, as I understood, the problem was “The real problem you have is the desktop manager (gdm3) seems not able to turn on so desktop is gone”. I did this:
via ssh (USB device mode) I installed nano editor on my Jetson (since it’s the best way to reach config files on Jetson via ssh):
sudo apt install nano
then I opened and correted a mistake in desktop resolution in /etc/X11/xorg.conf:
sudo nano /etc/X11/xorg.conf
and made a reboot:
sudo systemctl reboot
That’s it.
Below is a usefull link if there is a problem with gdm3 and or gnome:
