Hello, I just tried Fedora 14 Beta LIVE CD and noticed things are still problematic on my setup: - Laptop with radeon graphics - Attached to a docking station with external (DVI) monitor. The lid of the laptop is closed when the laptop is in the docking station, so only the external monitor is in use. Internal LVDS display should not be used at all in this case. Now what happens when Fedora 14 Beta boots up: - I can see the BIOS, grub and kernel booting up on the external monitor. - when GDM starts the external monitor goes blank/black !! - If I open the (closed) laptop LID I can see the internal LVDS display is enabled and GDM login prompt is there !! I was tracking this down, and it happens probably because the internal LVDS is always reported as 'connected' by the radeon driver, so it gets enabled even when the laptop lid is closed. The radeon/drm driver maintainer (Alex Deucher) confirmed this is not a bug, that's how it's designed to be, and the "policy" of enabling/disabling outputs is left to userspace! So, some component in userspace should check the ACPI lid state and based on that enable/disable the internal LVDS. On my laptop ACPI lid state works just fine: $ cat /proc/acpi/button/lid/LID/state state: open or closed, depending if the lid is actually open or closed. So the question is which userspace component should be taking care of disabling the internal LVDS when the laptop lid is closed? - plymouth - GDM - Xorg - gnome-power-manager - something else? Please let us know what you think of this.. This behaviour is very problematic for laptop users who use docking stations, so it would be very nice to get this resolved.. There are many bug reports about this problem on Fedora bugzilla for various Fedora versions.
