In the LattePanda instruction it says:

“This was a headache to set up. I first used a dedicated screen to connect to the wireless network and install the ssh server, and then temporarily use it from SSH.

Although it can be used normally after entering the desktop and manually changing the primary/secondary output, it then returns to the same situation after restarting, so I simply turned off the IGD output.

  • Check out How to Disable Internal Display from BIOS

  • The official site says:

BIOS->”Chipset”->”North Bridge”->”IGD-LCD Control”->”Force Lid Status”->”Off”

  • did not work, so I finally had to resort to the last reference:
  • K3dAR’s reply to the solution:
  • add kernel parameter: video=DSI-1:d

This becomes effective after restarting. If you want to enable IGD, follow the same steps as above and delete the sentence you added.

–

If we want to generate an image with IGD disabled by default, refer to the introduction of isorespin.sh, add grub content, and generate iso image parameters

as isorespin.sh -i xxx.iso –atom -g “video=DSI-1:d“
“

We did not go through all the steps here of the instruction in detail, but according to the developer of the instruction, it is possible with the LattePanda V1 running Lubuntu to set the the Default Output to HDMI. But to we have an image to download Lubuntu for LattePanda V1? Is this not an instruction for coders?

But all the same, if this problem can be solved, we are asking the question: who uses the LattePanda V1 with Lubuntu? Does it not take a lot of time to get everything running? Is there a demo available how to do it in a view easy steps which can easily be unterstood also by non-coders? And even if it should be possible to use the HDMI out with the LattePanda V1 and Lubuntu, is this a reason to increase the price for this device? Again, are these instructions in a state that it is suitable for the average user? Does it not take a lot of time to test it all and to check if we can get it all running?
