Hre is my boot log from my current session. The HDMI cable is plugged in during boot and the HDMI TV displays "No signal". Around ~12:59, I've switched from the current "Split-screen" setting to "Single screen" (selecting my HDMI TV) with gnome-control-center, and the DVI screen went black with a "no signal" message, whereas the TV displays "Unsupported resolution" for a while, then goes back to "No signal". I've then pressed the Power button of my computer in order to suspend it, then pressed the Enter touch of my keyboard in order to wake it up. The two screens then displayed the correct image according to the "Split-screen" initial setting. Switching to others settings in gnome-control-center works fine.
