--- Comment #5 from Aaron Lu <[email protected]> --- That could be, if the GPU's driver provides such functionality. The firmware claims supporting win8, so ACPI video will not register backlight control interface; if he uses nomodeset, then the GPU driver will not register either, so there is no backlight control interfaces left... Is there a reason why he uses nomodeset? If he doesn't use it, will the GPU interface appear and work? If so, then we can close this bug :-) -- You are receiving this mail because: You are watching the assignee of the bug. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
