Summary: LCD brightness constantly set back to 100% Product: ACPI Version: 2.5 KernelVersion: 2.6.27 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Other AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Latest working kernel version: 2.6.26.6 Earliest failing kernel version: 2.6.27 Distribution: Arch Linux Hardware Environment: Gateway MX6961 laptop w/ Intel GMA950 graphics Software Environment: Problem Description: Shortly after boot, the LCD's brightness gets set to 100%. I can set it back to the desired level using "echo 62 > /proc/acpi/video/VGA/LCD/brightness". However, there are many actions that will return the brightness to 100%, such as switching to a console with ctrl+alt+fn, or returning from xorg screen blanking. Just about anything that changes the monitor's mode is accompanied by a return to 100% brightness. Steps to reproduce: 1) Boot computer. Brightness will go to 100%. 2) Set brightness back to desired level using either /proc/acpi/video... or /sys/class/backlight... 3) Press ctrl+alt+f1. Brightness will return to 100% every time. 4) Leave xorg idle until screen blanks. When the screen is "woken up", brightness gets set back to 100%. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ acpi-bugzilla mailing list acpi-bugzilla@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/acpi-bugzilla
