Public bug reported: Apple PowerBook G4 (5,4) Ubuntu 7.04 (PPC) updated as of 06/02/07
This is a regression in performance Edgy --> Feisty. Brightness controls (on F1 & F2) behave extremely erratically. One press of the brightness down key turns off the display even when at maximum brightness instead of stepping it down by one. The brightness up key only works if it is held down - it does not step up brightness when pressed once. None of the brightness controls register properly in GNOME - although the brightness indicator overlay appears, the brightness bar is empty and is not used at all. Both of these things worked fine in Edgy - they have been broken in the transition to Feisty. In addition, there is no smoothness of brightness change at all, when turning off the display or changing of brightness levels. ** Affects: Ubuntu Importance: Undecided Status: Unconfirmed -- LCD brightness control very poor https://launchpad.net/bugs/83577 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
