HDMI for system A isn't turning on

Hardware Platform: DRIVE AGX Xavier™ Developer Kit
Software Version: DRIVE Software 10
Host Machine Version: native Ubuntu 18.04
SDK Manager Version: Example: 1.3.0.7105

Currently the HDMI port for A isn’t outputting anything. We believe it has something to do regarding X11. Flashing would probably be the easiest solution but if possible I’d like to avoid that for now.

Hi @Spoekels,

I’m not a expert on X11 so I would suggest you to get the log from another working DRIVE AGX system with the monitor for comparison.

Or below on your host system is the default filesystem and may be a good reference if needed.
~/nvidia/nvidia_sdk/DRIVE_Software_10.0_Linux_OS_DDPX/DRIVEOS/drive-t186ref-linux/targetfs_a/

Any other recommendations as I do not have a spare DRIVE AGX laying around.

Will using another monitor help?

anything to do with the erratum in https://developer.nvidia.com/DRIVE/secure/docs/DE-08933-001_v08.pdf.
Will the power sequencing help?

Got it fixed by changing the driver modeset, thanks for the help regardless!

Thanks for sharing. Could you let us know which command you fix your problem in case other developers encounter the same issue? Thanks!

I am getting this same error.

The system always powers up correctly, no issues. However, and only sometimes, the screen will blank/lock and when I attempt to wake it up it never powers up the monitors. This has only happened in the past year and a half or so as I updated my system to a newer build of Fedora (33) with newer drivers.

The system is running fine, I can log in via CLI and see all my processes running but can’t open the GUI so I need to reboot the system. I’ve tried playing with “xset -dpms” and such to no result.

Could you create a new topic for your issue? Are you using DRIVE or Jetson? This is a DRIVE forum in case you don’t know.
