Hello, I am also experiencing this problem.
During boot, the screen goes black and the display shows a "No signal detected" message. Additionally, the machine stopped responding to pings, so may have kernel panicked - but could not find any evidence of this in any logs.
I am using the machine as a server, so do not need graphics/X11. So my solution was also to disable the gma500_gfx module by blacklisting it.
