On my XPS L322X, BIOS Version A08 both in 3.8.0-22-generic and 3.8.0-23-generic the backlight control works. After boot, the backlight level is normal, and I am able to adjust it up anddown.
On my system, I did have issues on 3.8.0-21-generic, as described in the original post. I've also tried 3.8.0-20-generic, and this one works as well for me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1169376 Title: XPS13 backlight stopped working after update 3.8.0-18.28 To manage notifications about this bug go to: https://bugs.launchpad.net/dell-sputnik/+bug/1169376/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
