So I got my jetson tx1 today, and has so far been unable to get it to do graphics. I have ssh access to it and it seems to work fine as far as I can tell. It displays text as it boots, but as soon as it goes into X the screen goes black.
I have tried to flash it with various releases from the linux tegra archive, as well as the l4t installer.
When I first booted it I was able to interact with the console, and ran ~/NVIDIA-INSTALLER as prompted. Upon rebooting I was dropped into the black X.
If I kill the X server trough ssh my monitor loses the signal all together, and if I restart it I get the black screen.
Oh, and I have on two occasions heard the noise that the ubuntu login screen makes.
