With last upgrade to Ubuntu 14.10, (kernel 3.16.0-23-generic + fglrx 14.2), this bug is now solved with acpi_osi=Linux on linux boot command line.
So, I would propose to close the bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1074960 Title: [Toshiba L850D-11Z] Backlight keys don't work with fglrx-installer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/1074960/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
