"EDID Invalid" On Xubuntu 16.04
Display worked at first, but after a few reboots now dmesg reports this error and the display is no longer working.
Code:
[D] evdi_detect (dev=1) Painter is connected [D] evdi_painter_get_edid (dev=1) 54 c4 ff evdi evdi.0: DVI-I-1: EDID invalid. |

The information you provided indicates that the EDID is indeed invalid. The first three bytes that are printed out should be 00 ff ff.
What monitor is it? Does it work without problems if it's connected directly to any PC? Can you dump an EDID from it and attach here? Cheers, Michal |

Monitor is an Acer R240HY which works fine connected directly to the HDMI port on the same computer. FWIW, now dmesg reports 3 different bytes for the EDID: "54 64 52".

This is interesting. Any chance you could send us at least DL logs from /var/log/displaylink?

Thanks, I've raised this internally for analysis.

EDID And SIGSEGV
Today when I booted the driver produced a SIGSEGV ("Cannot access memory at address") error without a monitor plugged into the adapter. So I tried a different monitor of the same model with the adapter and got the following EDID:

DisplayLink version is 1.1.68. I recall trying 1.0.335 first; not sure if that is a factor. |
