I have a Lenovo ideapad 310, with an AMD A12 APU and kubuntu 18.10. My graphics driver are the mesa drivers from ppa:Dibaf/graphics-drivers, of which the current version is 19.0~git1811211930.
When I plug an HDMI cable to a TV, there is no image on the TV. In kubuntu's screen settings, only the laptop display appears. But xrandr says it has detected the HDMI TV:
$xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
eDP connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
1920x1080 60.05*+
1680x1050 60.05
1280x1024 60.05
1440x900 60.05
1280x800 60.05
1280x720 60.05
1024x768 60.05
800x600 60.05
640x480 60.05
HDMI-A-0 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 1152mm x 648mm
1920x1080 60.00*+ 50.00 59.94 30.00 25.00 24.00 29.97 23.98
1680x1050 60.00
1280x1024 60.02
1440x900 60.00
1280x960 60.00
1360x768 59.80
1280x800 60.00
1280x720 60.00 60.00 59.94
1024x768 60.00
800x600 60.32
720x576 50.00
720x480 60.00 59.94
640x480 60.00 59.94
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
And in kubuntu's screen configuration, clicking on the (i) button which I presume is for identifying the screens, both screen names appear superimposed on the laptop display:

Also commands such as:
xrandr --output HDMI-A-0 --mode 1920x1080
xrandr --output HDMI-A-0 --auto --same-as eDP
xrandr --output HDMI-A-0 --auto --left-of eDP
do nothing.
Any help? thanks!

UPDATE: It worked on another TV, a common LED TV. It worked almost instantly, only the KDE screen settings do nothing. I only could change from clone to extend desktop, etc., using xrandr. On my TV, a Sanyo smart TV, it still doesn't work. The same laptop on my TV, using Windows, works OK.
