@Po-Hsu, Please skip comment #7. Since latest kernel fixes this issue, it should be win8 backlight issue. Backlight control is moved to gfx after win8. video.use_native_backlight=1 is set as default after 3.16-r2.
Utopic release should fix this issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1332437 Title: [Dell Inspiron 5547] Unable to contorl brightness with fglrx driver on AMD Radeon R7 M260 [1002:6900] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1332437/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
