Kernel 4.7: Edid length too small

[davirtavares]

Here it is, hope it helps.

Update: I tested with a different monitor, still not working, the error message appears to be different tho.

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?

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 got the same error about EDID. Attached my edid information. Please note that the external monitor was working before I switched from ubuntu 16.04 to 16.10.
Now my pc crashes if I plug the docking station in. I have the latest driver installed

Update: so far we've narrowed down the problem to be specific to Intel+NVIDIA systems using nouveau, running Ubuntu 16.10.

It was working on ubuntu 16.04 not on 16.10.
I had some problems with my laptop and 16.04 that's why I switched to 16.10 (kernel 4.8.0-26-generic).

I have two monitors: Dell U2415 and Dell P2314H.
And the same problem with both.

Laptop: Acer Aspire VN7-591G, BIOS V1.13 01/08/2015

Thanks Michal!

Is this related to the opensource part of the driver (evdi)? If so, I can spend some time investigating, if there are any "How to contribute" or "How to debug" page, that would be even better
