Not recognising new TV connected via HDMI

[PMora4]

Hardware:

Intel Skylake i3 6100

ASRock B150M mainboard.

Samsung 55JS7200 TV.

Software:

Ubuntu Server 15.10, Kernel 4.4.1.

Description:

Trying to connect my HTPC box to a new television. If I disconnect HDMI from existing TV and plug it into the new TV then I get a picture. If I restart Ubuntu/Xorg server/Kodi after doing so, then it's no signal. Likewise, xrandr says it can't open the display.

If I reboot, I don't even see the BIOS screen on the new TV. If I connect back to my old LG TV, then unplug, I can see the screen again.

I've tried connecting using three different HDMI cables and every port on the new TV with the same result. I also tried a DVI to HDMI adaptor and got the same result.

I've tried connecting other devices, laptops to the same HDMI ports on the TV and they all work fine.

As I can't see the BIOS screen on the new TV I am thinking this is something quite low level, probably. If anyone has any ideas then I would be very appreciative!

Hi grantonstar,

Try with this open source graphics driver.

Hi Mike,

I replied in the bugzilla I raised for this. Can the drivers be installed via the command line? I'm running a limited Xorg (for Kodi) not a full desktop environment. Also, how do these differ from those in the kernel?

Thanks for replying,
