i followed your instructions, but it did not solve the problem. attached you can find the generated xorg.conf with the extra >>Option "ForceEnablePipeA" "true"<< line.
what i noticed in xorg.0.log is this: (II) intel(0): Output configuration: (II) intel(0): Pipe A is on (II) intel(0): Display plane A is now enabled and connected to pipe A. (II) intel(0): Pipe B is on (II) intel(0): Display plane B is now enabled and connected to pipe B. (II) intel(0): Output VGA is connected to pipe A (II) intel(0): Output LVDS is connected to pipe B (II) intel(0): Output TV is connected to pipe none is that the way it is supposed to be? ** Attachment added: "generated xorg.conf with the modification" http://launchpadlibrarian.net/16148961/xorg.conf -- laptop backlight is turning off https://bugs.launchpad.net/bugs/247315 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
