I have an AMD A9 CPU with onboard video. First I couldn't install LE because as soon as it got to the USB boot menu it would just start outputting a black screen on the HDMI at 1360x768. I had to use VGA to be able to even install it.
After installing it I can't boot from HDMI either, again just a black screen... If I boot without VGA in and with the HDMI in, then I get no video at all on the VGA, and the black screen on HDMI.
I have booted by VGA to get to the display settings, but the only outputs it shows are "default" or DisplayPort0, when the machine doesn't even have DP? Changing it to DP does nothing. It only shows resolutions up to 1360x768.
There's nothing wrong with the HDMI, it works fine in the bios etc.
I also can't access a tty terminal through CTRL+ALT+F*, as I just get the following error:
