That's weird for me. the 3 devices with uninitialized properties stands for CRT/TV/DVI devices that don't support backlight switching. we only need to take care of the LCD device which has backlight support. > [ 154.681803] ACPI: set_brightness with brightness 0 should be called 0 is also a weird value to me. can you please check your backlight values by "cat /sys/class/backlight/acpi_video0/actual_brightness", and check if the video driver wants to restore the same value during resume. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. ------------------------------------------------------------------------------ Throughout its 18-year history, RSA Conference consistently attracts the world's best and brightest in the field, creating opportunities for Conference attendees to learn about information security's most important issues through interactions with peers, luminaries and emerging and established companies. http://p.sf.net/sfu/rsaconf-dev2dev _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
