HDMI support in Linux

raj010 · 11-10-2010, 01:14 AM

Hi,

I want to know whether by default Linux supports HDMI???

If yes, where can I find HDMI support in Linux driver code??

Hello,

if your looking for the support for your graphicsadapter you'll have look into the kernelconfiguration in devicedrivers->graphics support. There you can chose the support for your card. If you have a very new card, be sure to look also in the section devicedrivers->staging drivers.

Thanks for your reply.

I'm planning to use Intel QM57 chipset. In the data sheet, it is saying like chipset is having integrated graphics support. So I want to confirm whether Linux support is available for HDMI in QM57.

Well, The only thing I found was this: http://www.thinkwiki.org/wiki/Intel_QM57
The chipset is supported by Linux. But there's no hint if HDMI is supported or not. Otherwise one finds documentation about hdmi in the kerneldocumentation. In the Documentation directory of your kernelsources execute:

Code:

grep -Ri hdmi

maybe that helps.

I booted to my Q150 on a number of distros.

I'd assume a video card that in only hooked up to a hdmi would have better luck on a boot. Other issues are if the monitor/tv report correctly.

Basically hdmi is the pin for pin of dvi.

Please be aware that your chipset has no integrated graphics chip. The graphics-chip for this chipset is integrated into the CPU, so you have to choose the right CPU to get integrated graphics. The QM-57 is a mobile chipset, so laptop-manufacturers can build it with mobile graphics from nVidia or ATI, too.

Thanks for the Information. I will be using Intel i5-520m CPU, which is having Integrated Graphics Media Accelerator(GMA HD). Does Linux supports GMA-HD??

According to this site it should work, but will get better performance in future, or with newer kernels.
