I've just updated on Oneiric 14R N4010. The brightness keys are now working without any kernel boot options:
bcbc@ubuntu:~$ uname -a Linux ubuntu 3.0.0-8-generic #11+kamal~mjgbacklight5-Ubuntu SMP Fri Aug 12 23:53:11 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux bcbc@ubuntu:~$ ls /sys/class/backlight dell_backlight intel_backlight bcbc@ubuntu:~$ The only thing is that when the function keys are pressed, the popup display show a computer with a solid bar underneath that doesn't change, however, if I go to System settings, Screen, the slider works appropriately. As far as I am concerned, this is working great. Thank you for your effort to get this fixed and also providing the ppa's. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/568611 Title: Screen brightness control fails on Dell Studio 1558 To manage notifications about this bug go to: https://bugs.launchpad.net/null/+bug/568611/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
