My jetson tk1 L4T 19.2 board had the problem of logging out abruptly which many people have been having. Yesterday I downloaded Teamviewer, just the .deb, i hadn’t installed it yet and it suddenly went blank(Black).
When i restarted, it started loading usually and even displayed the nVidia logo but after that the screen goes blank.
If i press Ctrl + Alt + F1 it shows the command line. I tried running the following code which was of no use:
sudo apt-get install --reinstall unity
sudo apt-get install --reinstall ubuntu-desktop
I tried this too:
sudo nvidia-xconfig
when i write startx it says the following in the log file /var/log/Xorg.1.log, some X11 paths are missimg:
