Chaud changed: What |Removed |Added ---------------------------------------------------------------------------- Attachment #125562|0 |1 is obsolete| | --- Comment #15 from A. Chaud --- Created attachment 125642 --> https://bugs.freedesktop.org/attachment.cgi?id=125642&action=edit backlight control w/ gpio check Thank you for the comments. This version removes the powerpc ifdef and exposes the full range of brightness values. I also fixed the formatting. Let me know if I missed any of it. Regarding the 0x535. It's a workaround for bug 31120. The lower half of the register gets set to 0x7fff upon waking from suspend which disables the backlight. This changes it back to a working value. -- You are receiving this mail because: You are the assignee for the bug.
