http://forums.fedoraforum.org – Hi! I'm new in this forum. I have a problem with my laptop lenovo s400u with fedora 19. The system runs almost fine, but when I close the pisplay or when I suspend it (pressing the on/off button) the problem begins. If I want to restore the session, the displays appears black, but the buttons works well; then I have to force shutdown and turn on again. I have another problem with hdmi port. Apparently it doesn't work, I have connect it to a projector and it doesn't recognize it. Can somebody help me? (HowTos)
