We will always have a 1080p monitor attached to our jetson nano, but the EDID doesn’t send because it’s attached to VGA via hdmi->vga cable. How do I set the desktop resolution to permanently be 1080p from boot so it never changes?
Currently, when I use NoMachine to remote into the jetson, it shows at 480p, then I change it to 1080p, and when I log out of NoMachine it reverts back to 480p again. How to I permanently lock it at 1080p regardless of if I’m remoted into it or not?
You may try adding this into /etc/X11/xorg.conf:
Section "Screen"
Identifier "MY-SCREEN"
DefaultDepth 24
SubSection "Display"
Virtual 1920 1080
Depth 24
EndSubSection
EndSection
and restart X or reboot.
Yeah, that didn’t help. It still reverts to 720x400 on reboot. I don’t know what’s going on with their monitor setup since this is at a remote site.
Is there a way to lock all display outputs to 1080p so that it never changes without sudo?
Not sure I correctly understand:
Do you mean early boot ? The screen section in xorg.conf only applies after X has started.
Or do you mean that after reboot, the Desktop resolution has changed ? In such case you would enable X debug mode with option ModeDebug in /etc/X11/xorg.conf:
Section "Device"
Identifier "Tegra0"
Driver "nvidia"
# Allow X server to be started even if no display devices are connected.
Option "AllowEmptyInitialConfiguration" "true"
Option "ModeDebug"
EndSection
then save, reboot, and check file /var/log/Xorg.0.log.
I added the lines you mentioned in your first response to xorg.conf. I’m not able to see the machine booting because it’s remote across the USA for me. I know there’s a monitor attached to it, but I don’t know if it’s straight HDMI or if there’s some conversion cable situation going on there. I do know it’s capable of 1080p, so we’d like it to always display in that resolution no matter what state it’s in. When I connect to it via NoMachine, and it’s in 1080p via the system settings (not xrandr or other command line utilities), and I reboot, when I reconnect to it via NoMachine the resolution is back to 720x400 again.
I’ll add the logging to the system and try again when I get a chance.
May also be a NoMachine configuration issue. See NoMachine - Configuring how you view the remote desktop if it can help.
Here’s the log. Near the end you can see it trying to set the display to 1080p, setting it to “NULL”, then 720x400, then the last line is me manually setting it to 1080p in the settings.

Are you sure this is the log after rebooting with ModeDebug enabled ? I would expect more logs about various modes, but I may be wrong.
Maybe you would try adding a Monitor section for your case.
NoMachine is not the GUI you think it is. What the other person sees at the actual Jetson is normally via the X server. You are not running ssh forwarding, but this might partially explain that NoMachine is its own graphical server separate from what the Jetson shows up as having:
The gist of this:
ssh with either the “-Y” or “-X” argument, the remote system will instead see the events, and the GPU and software of the remote system will be what interprets those events and creates what you see on the display.echo $DISPLAY”, then it will tell you the designation of the server which is visible to that Jetson user.echo $DISPLAY”, then if and only if it matches the local $DISPLAY will the two be the same (and perhaps not anyway in some cases).$DISPLAY as “:0.0”. Remote systems via a virtual server will usually (it is traditional, and is not enforeced) be something like “:10.0”.xorg.conf to run a certain resolution, and it is being applied to the local X server, then I would expect the virtual server to not see (nor use) that setting.X server logs (including virtual) are located as naming convention:
/var/log/Xorg.*.log
What do you see from:
ls -ltr /var/log/Xorg.*.log
Note that the “-ltr” means it will reverse sort based on timestamp of last modification of the file. Are there files with two different names? Those names in the wildcard “*” are the $DISPLAY.
From my jetson logged in via NoMachine:
$ echo $DISPLAY
:0
and results of ls -ltr /var/log/Xorg.*.log:
$ ls -ltr /var/log/Xorg.*.log
-rw-r--r-- 1 root root 18571 Jun 14 10:03 /var/log/Xorg.0.log
What NoMachine is doing, as far as I’ve read, is hooking into the existing running xserver and streaming the composited graphics for the currently logged in user. I’m not familiar with what’s going on under the hood on a lot of this stuff so I could be wrong.
We have other jetsons in the field that are either running headless or on a monitor that don’t have this problem. It just our latest one in the field that’s having this issue.
NoMachine does indeed hook in to the server, but from what I know (and I could be wrong, I don’t use NoMachine) this requires a modified server on the Jetson itself. However, the timestamp on that file is apparently from right about now (are you or the Jetson are in an Eastern Standard Time zone?). So this is likely the correct server and log if you combine it with the $DISPLAY.
However, it is still possible that your client on the remote PC is able to run at a higher or lower resolution. The earlier log does show the NVIDIA module loading, so it seems the server is running correctly.
Does NoMachine have any documentation on setting resolution? What I find most interesting is that your xorg.conf has the “ModeDebug” which @Honey_Patouceul asked for, but the log does not show the mode pool. It is as if the server log is not from the xorg.conf with the ModeDebug in it. @Honey_Patouceul gave a URL for NoMachine configuration, which I have not read, but I am wondering if there is anything there about the location of xorg.conf, such that it might be ignoring the config file and really using some other config file in another location.
