I was using Ubuntu 11.10 (32 bit) on a ThinkPad W510, and having this problem. Fn+Down decreased brightness by 2 steps, and Fn+Up increased it by 3 steps.
I just changed my installation to Xubuntu 11.10 64 bit, and am having the same issue, thus it's not specific to Gnome nor KDE. I don't have HAL installed. The two commands below have no effect: /etc/init.d/acpid stop /etc/init.d/hal stop (No such file or directory) The temporary workaround is described in the comment by Kuba Górski. I can also overwrite the brightness file to set the desired level (0-15). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/207473 Title: Screen brightness double level changes on Dell laptops To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/207473/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
