** Description changed: I'm using Ubuntu Intrepid. I recently bought a new monitor to use with my Laptop (Acer Aspire 1642WLMi with Intel graphics card), and I'm using xrandr to switch to two monitors. The commands I use are: xrandr --fb 1280x1824 --output LVDS --mode 1280x800 --output VGA --mode 1280x1024 --below LVDS --verbose to turn the monitor on, and xrandr --fb 1280x800 --output LVDS --mode 1280x800 --output VGA --off --verbose to turn it off. The problem is that when I turn the monitor off, I return to the login screen, I'm assuming because X11 restarts. This doesn't happen all the times, it usually doesn't work when I have been working on a session for some time. Some errors I found in some logs: /var/log/gdm/:0.log.2: (EE) intel(0): underrun on pipe B!
