Package: src:linux
Version: 4.18.20-2~bpo9+1
Severity: normal
Dear Maintainer,
After upgrading and booting linux 4.18.20 from stretch-backports, I don't get
any output from my TV (samsung smart tv) if set to it's maximum resolution.
It works correctly (with sound as well) if it is set to lower resolutions like
1680x1050, or 720x576, but when set to 1920x1080 the TV says 'No signal', as if
it were not connected. Even during boot.
Cinnamon the desktop environment I'm using seems to believe everything is being
displayed, because I can move windows to the TV but the TV will remain in 'No
signal'. Lightdm seems to believe the same because the login dialog is
displayed on that monitor but it's completely unaccessible unless I unplug the
HDMI offcourse.
It was working correctly with linux 4.18.6, and still does.
