Hi, > changing the brightness on my Thinkpad X230 with Intel HD4000 > graphics, stopped working after commit 886129a8eebe (ACPI / video: > change acpi-video brightness_switch_enabled default to 0). Changing > it back to 1, fixes the problem, if "acpi_osi=!Windows 2012" is also > set. Before that commit just setting "acpi_osi=!Windows 2012" was > enough to get changing the brightness working. small correction: It setting "acpi_osi=!Windows 2012" does only help when using a kernel with commit 886129a8eebe as HEAD, with v3.16-rc4 setting video.brightness_switch_enabled=1 and acpi_osi=!Windows 2012 or just one of them, does not make changing the brightness work again. > > > With best regards, > Julian Wollrath -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
