Connecting a TV on HDMI output

Hi,

I'd like to watch movies on my TV through the HDMI output. I tried :

$ xrandr --output HDMI --mode 1920x1080
warning: output HDMI not found; ignoring
xrandr --output HDMI1 --mode 1920x1080
warning: output HDMI1 not found; ignoring

My cards are :

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev a1)

I though the problem was that my nvidia card (which has the HDMI output) was not used as I installed bumblebee (with the nvidia driver) and bbswitch, which cut the card. But even if I do "optirun xrandr [blabla]" it does not work.

Thanks

Re: Connecting a TV on HDMI output

What is the output of xrandr (with no arguments)?

Re: Connecting a TV on HDMI output

I don't see any mention of HDMI in your xrandr output. It needs to be there. I suppose it's a problem with your nvidia drivers, but I'm not sure as I don't use nvidia. For comparison, consider my own outputs:

$ lspci -nnmvk | awk '/VGA/,/Driver/'
Class:	VGA compatible controller [0300]
Vendor:	Intel Corporation [8086]
Device:	2nd Generation Core Processor Family Integrated Graphics Controller [0116]
SVendor:	Acer Incorporated [ALI] [1025]
SDevice:	Device [0504]
Rev:	09
Driver:	i915

$ xrandr 
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
   1366x768       60.0*+
   1024x768       60.0  
   800x600        60.3     56.2  
   640x480        59.9  
VGA1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)

And when I want to switch to hdmi:

xrandr --output HDMI1 --auto

Re: Connecting a TV on HDMI output

Ok... So I guess I have a problem with my nvidia driver or bumblebee. I'll have a look to the wiki again I may have missed something (but tomorrow, it's time to sleep now !).

Thanks a lot for your help

Re: Connecting a TV on HDMI output

You've got an Optimus setup. The HDMI is connected to the nvidia card, which makes it a bit of a hassle.

Did you read https://wiki.archlinux.org/index.php/Bu … e_monitors ?

Yes I read it. But I don't understand it well enough to adapt it myself to my case...

Up, I'd really appreciate some help to adapt this file (or even just a link to some good doc).

Re: Connecting a TV on HDMI output

I have the same problem, I dont't know the HDMI port is connected to my intel video card or nvidia card.
