Ubuntu 13.10 para LG TV via HDMI

1

Não consigo conectar uma caixa Ubuntu 13.10 a uma TV inteligente LG LED 1080p 240 HZ com 55 (modelo # 55LAS400) via HDMI. Às vezes, eu só pego uma tela verde na TV ou, outras vezes, ela não reconhece a TV.

Conectar a um monitor ASUS via HDMI ou VGA não tem problema, então eu sei que o cabo está OK. Estou usando uma placa gráfica ATI Radeon 5450 HD e esse problema ocorre com os drivers de código aberto X.Org e fglrx.

A página HDMI no wiki do Ubuntu discute que as modelines da TV HDMI estão com defeito. Eu tentei a abordagem DVI:

If your television has a separate DVI port, you can try connecting to that (try replacing the HDMI->HDMI cable with an HDMI->DVI cable, with the DVI end hooked to the TV, and HDMI on the computer). If you're able to get a valid signal there, take note of its modeline and try that with the HDMI->HDMI connection. Over DVI, the TV sometimes will report a non-interlaced native resolution the video driver can handle.

Esta é a saída de '' xrandr --verbose '' quando ambos HDMI (HDMI-0) e VGA (VGA-0) estão conectados à TV LG, mas a TV usa a entrada VGA. Nesta configuração, a TV nem reconhece a entrada HDMI, no entanto, o Ubuntu reconhece que o HDMI-0 está conectado.
