<pre>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
X/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 or grub bootloader 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.
some logs:
dmesg: <a href="http://paste.ubuntu.com/15074111/">http://paste.ubuntu.com/15074111/</a>
xorg.log: /var/log/Xorg.0.log
I've tried connecting other devices, laptops to the same HDMI ports on the TV
and they all work fine.</pre>
