Nothing new with kernels in 13.10. Last kernel which is able to control backlight (after a suspend/resume cycle only) is 3.8.0-22.
Something strange is that I filed bug #1240005, which has been confirmed, and which is able to fade the screen, with any kernels I tried. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1190341 Title: Backlight stopped working after update of linux-image To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1190341/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
