I have a Dell Inspiron 660s with an HDMI monitor. I'm trying to install Ubuntu 12.04 LTS, and after I choose "Install Ubuntu" from the boot menu, the screen shuts off and I can't see anything. How do I get the Ubuntu installer to work with an HDMI monitor?
I ended up just using the Mythbuntu installer, which seems to use a slightly different image and boot settings and works fine with HDMI. By default, it only installs a stripped down XFCE desktop, but installing the ubuntu-desktop and gnome-shell packages installs the normal Unity/Gnome desktop.
