Full Version: [SOLVED] Black screen when switching to 50Hz

Hey folks,

in the past days I did several major system updates including kernel & profile switch,
now I have some problems with 50Hz-playback in kodi and do not know, where to start to figure them out.

I have "adjust display refresh rate" set to "always" which worked fine for all framerates.
but now when starting a 50Hz-video, the screen goes black. My TV reports 50Hz, screen stays black and nothing happens.
Kodi doesn't crash, and pressing the "Stop"-Button gets me back to the menu as usual.

So I disabled the "adjust framerate"-option and noticed, if I change the kodi system display settings to 50Hz I also get to a black screen.

I do not see any errors in the Xorg.log nor the kodi debug.log, heres a cut of the unsuccessful frame rate change to 50Hz (and falling back to 24)

Code:

debug.log including start and two tries of setting display refresh rate to 50Hz: https://pastebin.com/Nn6M7hqw

may you have one idea where to start locating the issue?

I use

kodi 17.4-r1
libva-1.7.3
libva-intel-driver-1.7.3
mesa-17.0.6
xorg-server-1.19.3


thx all
Can you pastebin the result of the xrandr command on your Intel box? (if that is supported in Gentoo...)
Just wondering which capabilities the TV has. Smile
thx for the quick answer!

here you are: Smile

but let me point out that I didnt change any hardware and it worked before,
so its most likely a software issue.
You use a manual xorg.conf - remove that please.
huh, no idea where it came from.
thanks, 50Hz playback is working again after removing xorg.conf!
