HDMI not detected in Bunsenlabs Lithium

Hi there,

Hello dear members of Bunsenlabs community. I am a nooby who need your help and knowledge...

I've got trouble on my laptop HP pavilion 17-cd0077nf, regarding my HDMI.
When I use xrandr under BL Lithium, I obtain this:

installed@bunsenlabs-lithium:~$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 382mm x 215mm
   1920x1080     60.02*+  40.02 

no mention of my HDMI.

But when I use a live session of ubuntu studio and make xrandr in a terminal, I obtain this:

live-session@ubuntu-studio:~$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 382mm x 215mm

So, I think that the problem is not with my laptop, but with my bunsenlabs installation or kernel.
What do you think about this ???
Is there a way to use my HDMI with Lithium ???

Re: HDMI not detected in Bunsenlabs Lithium

Is your nvidia graphics card in use? Is this an optimus laptop, and do you have the correct settings in your BIOS?

Ubuntu deals with nvidia graphics much better OOTB than a bare-bones BL install, where you may have to do some configuration yourself.

You may also need specific kernel parameters for your hardware - I know I do with my nvidia laptop.

glxinfo can give some information. For example:

glxinfo -B | grep renderer

Re: HDMI not detected in Bunsenlabs Lithium

Hi Damo,
thanks a lot for your quick reply.

Is your nvidia graphics card in use?

Well, how can I know if it is in use or not ? Is there a command line ?


Is this an optimus laptop

I don't know. I don't think.
Here my laptop caracteristics: https://support.hp.com/fr-fr/document/c06545442
see nothing regarding optimus tech.


do you have the correct settings in your BIOS?

Well the bios is in fact a bios simulator, here a documentation: http://h10032.www1.hp.com/ctg/Manual/c06525446
I find nothing regarding hdmi in it.


And: why an unbuntu-studio live session detect my HDMI, and not my Lithium ??? Make myself configurations why not... but I don't know wich ones...

installed@bunsenlabs-lithium:~$ glxinfo -B | grep renderer
Extended renderer info (GLX_MESA_query_renderer):
OpenGL renderer string: Mesa DRI Intel(R) UHD Graphics 630 (Coffeelake 3x8 GT2)

Re: HDMI not detected in Bunsenlabs Lithium

As I pointed out, Lithium is a lot lighter than Ubuntu, so it doesn't include the extra utilities required to detect and configure all your graphics capability. It probably also uses a newer kernel, and therefore newer hardware drivers.

My BIOS has a switch to choose either discrete or integrated graphics ie a separate card or onboard Intel.

The glxinfo command shows you are using Intel graphics, not the nvidia. You can get hardware and graphics infomation by running hardinfo, or

inxi -G

It may be that Debian Buster is too old for your hardware, so you could try installing a new kernel from backports.

Re: HDMI not detected in Bunsenlabs Lithium

Don't know if this helps or not, but the new nVidia Riva/Geforce driver is not enabled in the latest linux-image-4.19.0-10-amd64 as installed during bl-welcome
nVidia Framebuffer Support is also disabled.

Re: HDMI not detected in Bunsenlabs Lithium

ok Damo, I made inxi -G, and you're right: I use intel graphics.

Graphics:
  Device-1: Intel UHD Graphics 630 driver: i915 v: kernel 
  Device-2: NVIDIA driver: N/A 
  Display: x11 server: X.Org 1.20.4 driver: modesetting unloaded: fbdev,vesa 
  resolution: 1920x1080~60Hz 
  OpenGL: renderer: Mesa DRI Intel UHD Graphics 630 (Coffeelake 3x8 GT2) 
  v: 4.5 Mesa 18.3.6 

Lithium is a lot lighter than Ubuntu, so it doesn't include the extra utilities required to detect and configure all your graphics capability

Is there a way to install those utilities, and which are those missing utilities ?

I will try to install kernel from backports. First I have to search on the web how to do it.

Let you know if it change something.

Many thanks  smile

Why search whole internet when it's in the forumthread: How to install a newer kernel version in BunsenLabs under Getting Started

Really ? so I have to take a look before installing new kernel. thanks for the tip smile

I follow the post to install new kernel, and i do it with buster-backports.
No difference: no HDMI detected xhan i make xrandr.

regarding driver nvidia to install, i install:
  nvidia-detect
  nvidia-legacy-390xx-driver
  nvidia-modprobe
  xserver-xorg-video-nouveau
it make no difference...


aaaarrrggggg sad

any ideas ????
