10.6.8 update: screen brightness issues when hooked to external monitor

Maybe it's the "Automatically adjust brightness as ambient light changes" setting in Display Preferences.

On my MacBook, the camera thingy at the top of the screen doubles up as an ambient light sensor.

Same here, after updating from 10.6.7 to 10.6.8 on a macbook pro (model 2008).

Screen is not evenly lit, i.e. alternating rays of light starting at the bottom of the screen.

Please, update patch ?

update:

after repairing permissions (using iTools) and restarting the computer problem was solved !

I'm getting the exact same thing. When I connect my somewhat ancient (mid-2007) MacBook to my Cinema display and turn the MacBook brightness right down it increases and decreases by a small amount apparently at random. No biggy but irritating all the same. There's no ambient light sensor so it can't be that.

Seeing the same issue of un-blacking my MacBook Pro (2009) display after upgrading to 10.6.8.

Since updating to 10.6.8 (using the combo updater rather than the delta) from 10.6.7, my 2009 15.4" MBP's display has shown this symptom in the absence of an external monitor.

After I changed the display sleep setting in the Energy Saver System Preference from 6 minutes to Never, the symptom evidently has gone away.

Hope this helps other users experiencing this symptom.

Same problem here with a MacBook Pro. I have the notebook connected to a Cinema Display and thus manually dimmed down completely my MacBook Screen. Now after updating to 10.6.8 my MacBook screen dimms up at the time when it would normally dimm it down if the screen was "enabled".

I tried several steps to fix that:

- Dis- and reconnected my external Cinema Display.

- Changed display and energy safer settings in system preferences.

- Fixed file permissions.

- Did a PRAM-reset.

Nothing helped. 😟

Please help us!

Same issue !!! 10.6.8 is crap !!!

i wish i had never upgraded !!! 10.6.7 was working perfectly fine !!!

and the fuc**** Apple people don't even reply to forums .. atleast read our problems and update a patch...

Same thing happens to my 2010 i7 MacBook Pro.

I usually have the laptop monitor on complete darkness - but if I leave the computer untouched for several minutes, when the laptop monitor would usually begin to dim (if it was on), it will instead turn on -even though I left it turned off (brightness all the way down).

This started after 10.6.8.

Same here on a 2010 MBP.

Seems like laptop screen brightness buttons control was broken in this update. I have the same issue and brightness doesn't change if I press F5 or F6. The indicator shows up, it's value is changed but brightness stays the same.

Although if you go to System Preferences ->Displays you can change screen brightness manually by the "Brightness" slider. In my case it was closer to the left side, so the brightness of my laptop screen was very low. Now, when I moved to the right I can see my screen in normal colors 🙂.

I hope it help you all for the time being.
