Summary: Asus UL30VT backlight control only works with acpi_osi="Linux" acpi_osi="!Windows 2009" Product: ACPI Version: 2.5 Kernel Version: 2.6.38 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other AssignedTo: acpi_ot...@kernel-bugs.osdl.org ReportedBy: alex.william...@redhat.com Regression: No Created an attachment (id=53362) --> (https://bugzilla.kernel.org/attachment.cgi?id=53362) Asus UL30VT Bios 211 DSDT Asus UL30VT backlight control only works with acpi_osi="Linux" acpi_osi="!Windows 2009". Without these options, I get a desktop notification for the brightness when using the Fn brightness up/down keys, but no change in display brightness. Likewise the sysfs brightness control thinks it's doing it's job when I read and write the file, but there's no change in the display state. Either method causes the display brightness to change when the system is rebooted, as if Linux setup the change, but didn't actually flush it out to hardware. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Create and publish websites with WebMatrix Use the most popular FREE web apps or write code yourself; WebMatrix provides all the features you need to develop and publish your website. http://p.sf.net/sfu/ms-webmatrix-sf _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
