--- Comment #8 from Lan Tianyu <tianyu....@intel.com> 2013-05-06 07:33:54 --- So changing backlight via "/sys/class/backlight/acpi_video0/brightness" will not cause freeze. This prove ACPI backlight control is ok. Using functional keys will involve hotkey producing. Could you test with a terminal running "acpi_listen" to check whether the brightness changing hotkey is sent to user space before being freezing? -- Configure bugmail: https://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching the assignee of the bug. ------------------------------------------------------------------------------ Introducing AppDynamics Lite, a free troubleshooting tool for Java/.NET Get 100% visibility into your production application - at no cost.
