Kernel 4.7: Edid length too small
Hello, I'm using a DisplayLink with the kernel 4.7, as soon as I plug the device and try to start my X server it crashes with the folowwing error:

This is odd - the EDID is indeed too short. Could you attach all logs, gathered with our Linux Support Tool?

Thanks,
We can reproduce the issue with your original monitor. We should be able to fix it. As for the other attempt, there are no signs of loading evdi kernel module at all in dmesg? Regards, Michal |

You are right Michal.
I probably had unloaded it for being able to start X server. That's good news. The two displays are from LG, and they are very similar, despite their sizes, maybe the problem is related. I'm sending the files again. Please let me know if you need anything else. Best regards. |

I understand based on the earlier discussion it sounds like this is an EVDI problem? Is there a better place for us to track this(bug report or gitlab issue) so I know when I can look at updating *buntu on my laptop?
