Display brightness on Macbook Pro 5,4 …

Postby Linux Mind » Fri Jan 25, 2013 9:38 am

… under Linux Mint Nadia.

Hello out there, I am a complete Newbie to Linux and this forum, too, so first I wanna greet all of you - you have been really helpful to me in the last days when I fiddled around with my double-boot Linux installation on my 2009 Macbook Pro.

Nearly everything works fine right now, despite that dammed issue with display brightness which seemingly many of you already know quite well - I have been reading a lot ! Using F1 and F2, I can easily adjust the control on the screen - but display brightness itself does not change at all. Only when I flip down the display (susppend), wait a few seconds and then reopen the lid again will the display have the new brightness setting.

This effect came up when I changed to the NVIDIA 304.64 (stable) which I had to do, because I needed dual display support (before, the system used "Gallium something" as a driver) to my Geforce 9400 M card. Since then I am fiddling around with bkms and pommed and whatsoever I could find in the forums - with no change at all. Has anybody fixed that ? How ?

As well, coming from Mac OS, I am used to dragging objects around on the desktop from A to B in several steps with the touchpad. Now, everytime I draw my finger away from the pad (because I reach the boarder of either the pad or my fingers reach), the object sticks (could I describe that in an understandeable way ?) in the place where it is (e.g. a folder on the way between A and B), but where I did not want it to be. Is there a solution to this ?

Thanks in advance and bye,

I installed Linux Mint Olivia on a mid 2009 Macbook Pro (5,5) and I am having the exact same issue with the lcd brightness as Peter is. The fn keys will bring up the applet which will show the brightness slider changing however the changes wont take effect unless I close the lid and reopen it. Has anybody solved this issue, or is there at least a workaround?? I've been searching for a while now but I have yet to find a definite solution. Thanks in advance for the help.

I had the same problem. I just got this to work with a Macbook Pro 5,5. The solution is from another thread: viewtopic.php?f=49&t=136574

Here I just copy and paste what it says:

This will work with you Nvidia driver.
Open the Terminal and type: gksudo gedit /etc/X11/xorg.conf
Go down to the section that says: Section "Device"
Add the following line to this section, just above the last line that says "EndSection".
Option "RegistryDwords" "EnableBrightnessControl=1"
Save the file and reboot.
