Hi Team,
We are using xavier NX and 32.4.3 release , after connecting the DP port we are able to get GUI and it is working fine.
But when we are trying to read details using console ‘xrandr’ command is not showing result.
Following are result :
xrandr
No protocol specified
Can’t open display :0
xrandr
No protocol specified
Can’t open display :1
Can you guys help, what we missed ?
Thanks
Alks
Will xrandr give you a result if you use the terminal on the screen but not remote access?
Hi @WayneWWW,
We are using debug UART(/dev/ttyUSB0) and also tried on ACM0 node on host laptop using minicom.
Actually we have to get details of screen/DP/HDMI, need to get/set resolution using debug UART linux command/code.
Yes, I know your purpose but please just reply my question first.
Yes @WayneWWW, It is working on screen (checked on Display port terminal).
working : xrandr
$ echo $DISPLAY
:1
Does this only happen to DP? I just tried my HDMI monitor with same setup but does not have problem.
We don’t have HDMI setup. Using DP only.
Ok. I will check with my DP.
Hello,
I cannot reproduce your issue with my NX+ DP monitor.
Could you reboot your device and try again?
nvidia@nvidia-desktop:~$ export DISPLAY=:0
nvidia@nvidia-desktop:~$ xrandr
