Problems with HDMI output and Bumblebee

[Nebucatnetzer]

The problem, I'm experiencing is that the built in display rotates by
90 degrees when I'm connecting an HDMI cable but the second display
remains blank. Sometimes just nothing happens.

The notebook is a HP Pavilion 15-bc060nr with an Intel i7 and a NVIDIA
GeForce GTX 960M

The operating system I'm running is Debian Stretch.

What I've tried so far is:

• - Install bumblebee and the proprietary nvidia drivers

• - disable the nvidia card to only use the Intel GPU

• - booted both a Debian and an Ubuntu live USB stick
  it worked on Ubuntu but didn't with the Debian stick

• - various solutions I've found while searching on web
  especially this ones I found here:

• - https://wiki.debian.org/Bumblebee
  - http://forums.debian.net/viewtopic.php?t=115315
  - https://wiki.archlinux.org/index.php/Bu ... l.2FNVIDIA

The message I get when I run something with optirun is:

Code: Select all

[andreas@capricorn ~]$ optirun glxgears
[ 1821.044880] [ERROR]Cannot access secondary GPU - error: Could not enable discrete graphics card

[ 1821.044943] [ERROR]Aborting because fallback start is disabled.

However the fix in the Debian wiki which mentions this message didn't.


The message from the bumblebeed status message:

I'm really quite lost what I should try next. I know that it must be
possible to get it running because it works with the Ubuntu live
stick. However I would rather stay on Debian if I can help it.

I still wasn't able to solve this problem.

Among other things I tried today a live ISO of Debian Stretch which didn't work with an external monitor.
So I reckon I can sort of rule out my installation.

One thing which came to my mind is that the Ubuntu version I've tried was 17.04 which runs the 4.10 kernel.
Could this be the reason why it's not working on Stretch which runs 4.9?
