Description Luca Viggiani 2014-07-30 09:54:40 UTC

After upgrading to:

xorg-server        1.16.0
xf86-video-intel   2.99.914

on Arch Linux 64 bit (kernel 3.15.7), every time the computer is started, display brightness is pushed to 100%.

Before this upgrade, brightness level was restored to previous value.

The ddx doesn't change the brightness on startup... If you are convinced this is a ddx bug, please grab a full-debug log (compile with ./configure --enable-debug=full) and attach.

Any debug information? debug=full Xorg.0.log would be very useful, and so woul drm.debug=6 dmesg
