Re: Strange problem with VGA signal

Have the very same machine but utilise a low profile gpu with HDMI output.
Are the LCD screens connected and powered on when you initially power the
machine on? I've got the same machine and unless I've got the display
connected and powered on, I won't get any GUI when it boots but can still
connect via ssh.
