[Bug 1133168] Re: can't adjust brightness via hotkeys(Fn+F6/F6)
We probably need this patch to fix the issue. I have submitted this patch for SRU ago, but it will bring a pre-existing bug to light, so the kernel team reject it. I'll re-verify this patch now and re-send the SRU request. commit d627b62ff8d4d36761adbcd90ff143d79c94ab22 Author: Lekensteyn lekenst...@gmail.com Date: Tue Jun 26 00:36:24 2012 +0200 i915: initialize CADL in opregion This is rather a hack to fix brightness hotkeys on a Clevo laptop. CADL is not used anywhere in the driver code at the moment, but it could be used in BIOS as is the case with the Clevo laptop. The Clevo B7130 requires the CADL field to contain at least the ID of the LCD device. If this field is empty, the ACPI methods that are called on pressing brightness / display switching hotkeys will not trigger a notification. As a result, it appears as no hotkey has been pressed.

We need this patch to fix the pre-existing bug that will make the screen become black. But, this commit based on many other changes. commit 3739850b46f560a2be29287c3e5c2d1a7e0e Author: Daniel Vetter daniel.vet...@ffwll.ch Date: Thu Sep 6 22:15:44 2012 +0200 drm/i915: disable the cpu edp port after the cpu pipe See bspec, Vol3 Part2, Section 1.1.3 Display Mode Set Sequence. This applies to all platforms where we currently support eDP on, i.e. ilk, snb ivb. Without this change we fail to light up the eDP port on previously unused crtcs (likely because something is stuck on the old pipe), and we also fail to properly disable the old pipe (i.e. bit 30 in the PIPECONF register is stuck as set until the next reboot). v2: Rebased on top of the edp panel off sequence changes in 3.6-rc2.
