[Intel-gfx] [i915] monitor is not detected unless it was active during boot

Mon Sep 19 18:56:29 UTC 2016

Hi Maarten,

Is this the Debug message when you are connected to the external DP Port or the HDMI port? I want to know if the problem is with the native DP connector or LSPCON?
Also could you send the log that has the Video Bios Table information (VBT) information?

Subject: [Intel-gfx] [i915] monitor is not detected unless it was active during boot

Hi,

I have a monitor, that when connected a skylake system, doesn't ever come up when hotplugging or after resume. The "bios" seems to not have problems bringing it up, even at the native 3840x2160 resolution, and when it works, all modes are correctly read (checked via xrandr).

I tried both the HMDI 1.4 port, as well as the DP 1.2 -> HDMI 2.0 built in conversion chip.

This is the dmesg output I have when plugging in this monitor, the DP-2 connector is the one that should be detected.

Any advice on how to proceed?

Please be aware I am not subscribed to this mailing list, so please reply to me directly as well.

Maarten.
