If you use a serial console to see what goes on during boot there may be a relevant message. For serial console, see:
[url]Jetson TX1 - eLinux.org
What stands out is that it sounds like text console works initially (so video works, even if graphical mode does not), and that reboot causes even graphical mode to work (which means a lot of video requirements must have been met). Even so, what kind of cabling do you have? Graphical mode can have tougher requirements than text mode.
Also, once you use ctrl+alt+f1 and get a console, instead of reboot, you might check “dmesg | tail” and see if anything shows.
I do not think those are errors, but instead a normal part of startup. It looks more like the JTX1 is booting correctly, but video just isn’t showing up. In the case where it boots up without graphics mode video, could you save a copy of “/var/log/Xorg.0.log” and post that? You may want to quote it in the “block quote” forum function (see the tool bar during post, the “</>” is block quote).
Describe the video cabling as well, e.g., any adapters. Also, is this the original L4T JTX1 arrives with, or is this the R23.2 which just came out?
I am facing the same issue when there is abrupt power off or if shutdown process is not proper. In that case there is a blank screen and then if I do Ctrl + Alt + F1, I can see the console in text and if login and do sudo reboot now, next time it boots into desktop mode.
My question is can we stop this from happening or can we somehow by scritp check if there was an abrupt shutdown and do reboot automatically so that it goes do desktop mode
This is a full computer, complete with journaling file system. It has to be shut down properly (just like any desktop system), or temporary files will get left behind. You could mount the root partition synchronously, but this would be a terribly bad idea…if it were just a regular hard drive, performance would drop through the floor…but as eMMC, this would also wear out the hard drive much faster and limit its life.
An interesting project for a Jetson would be a mini-UPS…the power requirement is so low that tiny batteries could be used to automate clean shutdown.
