Hi to all!
I've just installed Slackware 14.2 on a new HP Probook 450 G5; it has onboard a "hybrid" video card, with an Intel chip and a "3d nvidia graphic"; as I know, the plan is to use the Intel one as powersave system and the other nvidia on other task requiring 3D acceleration.

But the second monitor connected through the VGA port is not recognised by the system and I obtain no output on this.

I tried to install nvidia drivers or the BombleBee packages but nothing! I still have no output...

Did someone bump in the same problem? There is any solution?
I read that somebody run out this problem (on Archlinux) installing new drivers Intel e Nouveau... May be the right way? Is somewhere a Slackbuild to compile and install this drivers? I saw that they are part of X11 layer...

Thanks in advance fore any reply...

did you check the system BIOS ?
you may have to enable it in the BIOS
look for svga or display in the bios

Thanks for the answer, but this was the first thing I cheched. I disabled the 3D nvidia chip, add more memory to the intel card... but nothing! The VGA output seems to be inactive, with no output on it...

ok did you try setting it up in Xor config

google for "Xorg configuration for dual head"

one thing I can tell you that you will need 2 device
sections and 2 monitor sections

it's Rob NOT Bob

I'm sorry but I don't think thax X could see a VGA not identified by RandR...
If I try to identify the secondary VGA output in randr I see only the laptop screen.
I think it's necessary to config via driver first the VGA output. And, yes, I tried to configure manually X server yet...

@xja

Try playing with xrandr :

Query the available outputs with:
And this should activate all outputs:

when I installed the NVIDA driver on my computer as part of the install it black listed the intel driver in udev
SO did you ever get the nvida driver installed ?
is the intel driver black listed

tip I couldn't get the nvida driver installed in run level 4
I had to go to run level 3 to get it installed
