I have additional information concerning this bug : At work I easely connect and get an output trough HDMI on an Asus monitor. At home I used to get the same on my LG plasma TV. Now the TV actually shows that it is connecting but the PC never sends an actual output signal to the TV.
So it has to be some sort of driver issue in this case -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1313071 Title: No hdmi video output in 13.10 Status in “xserver-xorg-video-intel” package in Ubuntu: New Bug description: I have a Lenovo thinkpad t440s I run Ubuntu 13.10 on it and routinely connect it to my LG plasma TV using hdmi. Up to this morning it has always worked well. This morning when I connect the HDMI, Ubuntu shows me two connected monitors in the display setting, but the TV receives no signal. I have recently upgrade my kernel to 3.11.0.20-generic.
