Marc Bevand: "However I discovered that what actually happens is that the moment i915.ko is loaded, the output switches to HDMI. I found this out by connecting a monitor to the laptop's HDMI output while the LCD panel was blank."
I do not think this is correct, rather I think what you are seeing is the HDMI port correctly detect a connection and begin using it. I can plug a VGA connector into my U160 and see the same behavior you describe, however, if you look at "/sys/class/drm/card0-*/enabled" I think you'll see what's actually happening here (At least what I *think* is happening...). To begin with, in my configuration, only "/sys/class/drm/card0-LVDS-1/enabled" says 'enabled', however, as I plug in a VGA connector "/sys/class/drm/card0-VGA-1/enabled" transitions from 'disabled' to 'enabled' and I see the expected output on the monitor. It looks very much like everything is working, except the LVDS output. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/608907 Title: [i915] Lenovo U160 Intel i7 620UM blank screen To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/608907/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
