I’m having trouble getting HDMI output on my Jetson, so I can only login via UART and SSH.
I followed the instructions for full install of r21.3-6-5 by running JetPackTK1-1.1-cuda6.5-linux-x64.run from host computer. That seemed to go okay.
I’m able to SSH in, and do SSH X forwarding. But of course the OpenGL examples don’t work on my host machine (VMWare running Ubuntu 14.04 on Windows 7).
The boot messages indicate “this pci device is not a vga device”, and my startx log reports “No screens found” immediately after “Loading extension GLX”. I’ve tried deleting the xorg.conf and letting it reboot, but it seems to auto-generate the same one as before. I tried sudo apt-get install nvidia-current, but that is not found. I tried adding repositories universe and multiverse, then apt-get-update, and retried the nvidia-current, but still no luck.
I’m also not sure how the JetPack installation (which involves complete top-down reflashing of the device) relates to the initial startup instructions which also tell me to reflash. I was able to run that when I pulled the Jetson out of the box, but I didn’t have an HDMI cable at the time, so I’m not sure if that would have run. I’m afraid to run the “getting started” flash instructions again in case in wipes out my entire JetPack installation, since that took quite a while to install.
I tried Xorg -configure, and that lists “nvidia” as one of the drivers available (along with omap, modesetting, vesa, and fbdev), but then tells me “No devices to configure”, and fails.
Finally, my HDMI cable is actually going through a DisplayPort adapter before reaching the monitor, so I don’t think that should be a problem, but I thought I’d mention it in case for some reason it prevents the detection of the monitor.
So to summarize:
- What’s the difference between the “getting started” instructions to flash the device, vs. the JetPack?
- How do I install and/or verify the nvidia HDMI driver?
