I don't think there is anything we can do in Linux kernel because ACPI video driver runs the AML code exactly as we expected, and exactly the same as it does on other Acer laptops, except that the backlight fails to change on this laptop. I think you need to use xrandr as a workaround for now, and wish there is a new BIOS released by Acer soon which fixes this issue. :) -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ acpi-bugzilla mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
