I have a problem with kodi 17. It has always been there since the start of kodi 17 across all versions (including the libreelec variations based on kodi 17). I have an Intel Broadwell 5500 and basically if you set the output to hdmi 1 (instead of default or edp1) the laptop screen goes blank but no picture comes through the hdmi. I have found a workaround to the problem but this involves starting kodi through Ubuntu 16.10 first after setting the display settings in Ubuntu first to use the hdmi 1, then when I log out of Ubuntu and into kodi directly the laptop displays correctly through hdmi 1 with no duplicate on the laptop screen (obviously with blank other displays checked). I didn't mind the workaround but after trying libreelec based on kodi 17 I am having the same problem only with no workaround as there is no other system to set the display settings. Sorry to have only just mentioned this but I thought others would have had this problem and lazily left it to someone else to report. I do apologise but I am staying in a hotel tonight with a TV that looks like it was lifted out of a skip and does not have an hdmi port (it's not even wide-screen loooool) however when I get home tomorrow night I will upload a debug of both kodi (and libreelec if you want?)

I see a similar behaviour. It worked well in 16, but after upgrading to Kodi 17 I see th following. I connect to the display using hdmi.

- Kodi Display settings : choosing "Default" or "eDP1" works. Choosing "hdmi1" = blank screen.
- available refresh rates are 59 and 60hz. With Kodi16 I also had 24 and 50.
- Kodi Audio settings : configured to use hdmi. Works in both decoded and passthrough modes.
- autorefresh rate does not work anymore : DEBUG: Resolution eDP1: 1920x1080 @ 59.93Hz (18) not a very good match for fps 50.000 with 2:3 cadence (weight: 0.521), choosing 60 hertz


Here are some debug log from playing 50hz content :

I think the problem arises in too old kernel and intel driver. Investigating.

Mostly kodi 17 / krypton works well or even better than 16, so I'm not in panic to change things.
Will do it in an orderly fashion.

[fritsch]

What should I make of this cut log?

[lama]

Nothing. As I wrote I was investigating myself. Just sharing.

Anyways, upgrading to kernel 4.4.0-21-generic fixes it, I gathered from some related threads and comments by you actually (fritsch).
Kernel version was 4.1 before, intel driver 1.6

After upgrading kernel to 4.4.0 I could upgrade to intel driver 1.7.1
And inside Kodi -> Settings -> Display, I could then select HDMI1 as display. Et Voila, all the refresh rates was back and working.

Sorry if I wasn't clear on the working on it myself part. You are very keen to help, I understand. Very much appreciated.

After upgrading kernel and driver, I still had a problem with blank display when i toggled my tv off and on.

Solved with a new file "/etc/X11/xorg.conf.d/20-intel.conf" (note that on mint/ubuntu the dir "xorg.conf.d" might need to be created)

Content of file :


Section "Device"
Identifier "Intel Graphics"
Driver "intel"

Option "ConnectedMonitor" "HDMI1"
Option "UseDisplayDevice" "HDMI1"

EndSection
