[Bug 538326] [NEW] nvidia-bl-dkms 0.16.1 breaks screen brightness (backlight) adjustment on MacBook 5.1 [Karmic]
Public bug reported:
On my MacBook 5.1, upon updating to nvidia-bl-dkms 0.16.1~karmic, the
brightness controls fail to have physical effect on the brightness of
the screen. The screen brightness remains at 100% brightness.
Pressing the brightness keys brings up the brightness indicator in the
notifications area, and cause the brightness bar to move up or down very
slowly (see Bug #357112), however this has no effect on physical
brightness. Similarly, using the slider under System -> Preferences ->
Power Management has no effect on physical brightness.
This is a severe regression. The 0.15 series was annoyingly slow to
respond, but this new series doesn't respond at all.
