I'm running Oneiric, Dell 14R N4010 Since applying the patch, the brightness keys work, but only to toggle the screen off and on.
I tried adding the boot option "dell_laptop.backlight=0" but it didn't make a difference. Before I added that boot option I had a dell_backlight entry in /sys/class/backlight along with intel_backlight, but it's now I only see the intel_backlight entry. 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 intel_backlight bcbc@ubuntu:~$ Here is the line from my grub.cfg: linux /boot/vmlinuz-3.0.0-8-generic root=UUID=18B4B7BBB4B799A8 loop=/ubuntu/disks/root.disk ro crashkernel=384M-2G:64M,2G-:128M quiet splash dell_laptop.backlight=0 vt.handoff=7 PS your Natty patch worked great on this computer. -- 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
