I have an Nvidia card. Was using Freya until a few hours ago, installed Loki and now the HDMI is 100% not working. The secondary display (a Hitachi TV) shows no signal at all.
sudo ubuntu-drivers autoinstall as instructed here, but it did nothing. I installed the Nvidia X Server Settings from the App Center, also nothign.
Drivers available originally:
After I upgraded the Nvidia drivers to 340.98:
$ lspci -k | grep -A 3 "VGA" 01:00.0 VGA compatible controller: NVIDIA Corporation G96 [GeForce 9500 GT] (rev a1) Subsystem: ZOTAC International (MCO) Ltd.

What can I do to fix this?
