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

2016-09-19 Thread Maarten Maathuis 
I checked both monitors, on displayport they work, on HDMI they share the
same trouble.

An interesting observation is that when plug the monitor into another
system which has an older nvidia card using nouveau (only HDMI is
available, card is too old for displayport).
It seems that the i2c connection is unreliable, sometimes more or less data
is retrieved, but never all of it seems, and sometimes none.

I wonder if there is some sensitivity to i2c speed.

My general observation of these monitors is that they are slow to turn on
on displayport (locking in a mode takes some time), but on hdmi it is
faster, is there some kind of throttling going on the displayport side that
is being ignored on the HDMI side?

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.

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

2016-09-19 Thread Maarten Maathuis 
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.
