Can you confirm that a "git revert 38f940dfea494d3093236f065392c431be06ae6e" fixes the problem? commit 273d34fbc43e54a8539fbe7efc1dca66bbb4e6dc Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Tue Sep 7 12:57:04 2010 +0100 display: Query current level after finding max value. The current backlight value is clamped to the valid range [0, max] and so as we queried the value before setting the max, we forced the current backlight to 0 and so set it to be zero on initialising the display. Fixes: Bug 30063 - start X will modify brightness value to zero https://bugs.freedesktop.org/show_bug.cgi?id=30063 which is a regression due to 38f940dfea494d3093236f065392c431be06ae6e. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> It works fine with the fixed commit. Thanks Chris. |
