Christopher, thanks for your support, but I believe that this is a very well documented issue with remedies like typing "echo 0 > /sys/class/backlight/intel_backlight/brightness" on the command line solves.
The big issue is that after the computer resumes from suspend, the brightness go 100% and the keyboard commands for brightness can't change the brightness until the command I stated above is executed on terminal. As I said, it was fixed in the kernels 3.8.0 - 3.13.7 and the bug was reintroduced on the kernel 3.14.0 and I can also inform that it is on kernel 3.14.1 and 3.15.rc1. I will wait until Apr 17th to upgrade my Ubuntu 14.04 and see how it behaves. I will report the issues/success here. As for now, I am back to kernel 3.13. -- 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: 8086:0166 [Dell XPS 13 L322X] 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
