I can confirm this on Thinkpad T410 with ubuntu 11.10. The way it's happening with me is:
1. Set manually the preferred brightness. 2. Wait some time (usually about 3 secs). 3. press a key or move mouse. 4. Screen goes to full brightness. I have the power plugged in. This is naturally very annoying. I disabled "Dim screen to save power" checkbox in "Screen settings" to avoid any possible "automatic adjustments" (that was the only related adjustment I found) and it still brings up the brightness to max. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/842459 Title: screen brightness is inverted To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/842459/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
