could not set the configuration for crtc 394

Sometimes when I boot the system.
There will be dialog like Attachments file dialog.png
showing “Could not apply the stored configuration for monitors could not set the configuration for crtc 394”
I think it may not fatal because this just happens a few times and I can just close this dialog or reboot the system and it is gone.
But I still want to know what is “crtc 394”?
or if I can disable this dialog showing up?



It looks like an issue to monitor. Could you see this issue with different monitor?

Also, there are similar issues over external ubuntu forum.

For example,

Hi Tim2016,

Have you clarified the cause? Is it monitor issue?
Is there any further support required?



I am facing the same issue on my Jetson Nano.


I am using jetpack4.4. Previously with jetpack4.3, I don’t have any such error msg alert.
I don’t see such msg alert on my Jetson NX (jetpack4.4).

Any solution found?
