Summary: HP EliteBook 8460p - Screen brightness not working Product: ACPI Version: 2.5 Platform: All OS/Version: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Power-Video AssignedTo: acpi_power-vi...@kernel-bugs.osdl.org ReportedBy: pali.ro...@gmail.com Regression: No Setting brightness level on HP EliteBook 8460p is not working. I tried these commans: # cat /sys/class/backlight/acpi_video0/max_brightness 20 # cat /sys/class/backlight/acpi_video0/brightness 20 # echo 0 > /sys/class/backlight/acpi_video0/brightness # cat /sys/class/backlight/acpi_video0/brightness 0 # echo 20 > /sys/class/backlight/acpi_video0/brightness # cat /sys/class/backlight/acpi_video0/brightness 20 It did not show me any error, but screen brightness was not changed. And setting brightness with Fn keys does not working (xev see scancodes, but nothing happened). When I disabled ACPI (with acpi=off in grub) brightness keys started working, but xev does not see scancodes. And all other Fn keys does not working (when acpi is disabled). And it is possible to change brightness (with Fn keys) in Grub. But when linux kernel is loaded (with enabled acpi) brightness keys stop working. -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ FREE DOWNLOAD - uberSVN with Social Coding for Subversion.
