256.35 and Dell e6410 extern Display

[Karl234]

I run an Dell Latitude E6410. The externel Display is connected via a Displayport to HDMI
Adapter.
With driver 195.36.31 everything works. With 256.35 the externel Display doesn't get recognized.

Any hint what is needed to get the external Display on 256.35 working again?

From everything I can see in your log, it looks like the display is getting recognized fine, but it's not activated when you start the X server. You have several metamodes in your xorg.conf:

Option         "metamodes" "DFP-3: null , DFP-0: 1920x1200 +0 +0;DFP-3: 1440x900 +0+0, DFP-0: null;  DFP-3: 1440x900 +0+0, DFP-0: 1920x1080 +0 +0;  DFP-3: 1280x800 +0+0, DFP-0: 1024x768 +0 +0; DFP-3: 1024x768 , DFP-0: 1024x768 +0 +0"

According to Xorg.0.log, it's selecting the first one by default, which has your external display off:

[    13.207] (II) NVIDIA(0): Setting mode "DFP-3:null,DFP-0:1920x1200+0+0"

Does switching to a different metamode work?

Perhaps my first post was not clear.

I run my E6410 in my office with an external Display witch is connected via a DisplayPort to HDMI Adapter. Driver 195.36.31 detect this Display fine. The Metamodes are used to switch by default to the external Display if it is connected. If the external Display is disconnected the notebook display is used. Switching Metamode does work as it should with 195.36.31.

With Driver 256.35 the external Display doesn't get detected at all.

In my first post I attached only the correct log file, which might be a bit misleading.

Here is the relevant Part from 256.35

So with 195.36.31 DFP-0 get detected, with 256.35 DFP-0 its not detected.
