I did a clean install of 13.04 64-bit on my brand new XPS 13 Developer's Edition laptop and let it pull the latest updates. It is now running kernel 3.8.0-23-generic.
The back-light control does not work. When I use the control, the on- screen 'progress bar' pops up and goes up and down per my key presses, but the actual brightness of the display does not change. I also tried the test kernels linked to in post #23 (and updated on May 1st, apparently). The brightness control does not work with it, either. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
