    external monitor (screen) 22' suddenly rests black

    Hi,
    after xubuntu 12.04 on my lenovo B560 (intel graphics) worked fine for some months now the external monitor/ screen rests black! BIOS and Grub are shown but with the apperance of the graphical login of XFCE the monitor claims: "no input signal". Windows7 on same laptop works fine. Please help, I need the external monitor 22' urgently because of video recordings with LibreOffice impress.

    Last time I worked with my laptop and external monitor / screen I started the laptop with power button and closed the lid directly after. The the external monitor displayed 1024x768px. I set in settings -> display the mode to 1650x1050 like xubuntu suggested and all worked fine a whole day. Next day I can't get the external monitor worked like described! Please help! Last months I didn't close the lid an all worked fine. Xubuntu seem to be very sensitive once the lid is closed while booting. I didn't expect that behaviour, I will never close the lid again ....! I hope I have not to install Xubuntu again ....

    @ I installed xubuntu 12.04 on another partition completely new. And the external monitor NOT works either!! Same behaviour! I installed all offered update. But no success. I have two 22' and one 17' monitor with serveral cables.Win7 on this laptop work fine with 22' external monitor, I tested it again just 1 minute ago! Even extendet Deskop. So it's a xubuntu problem. The resolution must be some configuration I lost in xubuntu. Xubuntu seems not be able to run a external monitor out of the box. Have you ideas?
