I updated the BIOS of this laptop from 1.33 to 1.37, no change. I then installed precise alpha 2 and upgraded, also no change. Still freezes.
Finally, I reinstalled precise alpha 2 but 32bits, not 64 as I had before, and now it works. I can dimm the backlight without having the laptop freeze. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/922037 Title: "reduce brightness" key freezes system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/922037/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
