the display backlight on those models with Nvidia graphics adapter is always at its maximum brightness after resuming from suspend, but the chip, and thus the driver, still reports the last recently set value. This updated driver fixes this issue, by re-sending the value upon suspend. Can anyone please confirm that it actually works?
Instructions:
1. Install the attached deb package and reload the module:
Code:
sudo dpkg -i mbp-nvidia-bl-dkms_0.11_all.deb
sudo rmmod mbp_nvidia_bl
sudo modprobe mbp_nvidia_bl
2. MacBookPro 3 and 4 users: Set display brightness to some low value, e.g.:
Code:
sudo echo 1 > /sys/class/backlight/mbp_backlight/brightness
, suspend, resume and report whether it works.
3. MacBook 5 and MacBookPro 5 users: This might also work for the new 5th generation models. I don't have these machines and thus cannot test it. Please check out this driver and report whether it works at all.
4. If it didn't work, remove the package:
Code:
sudo apt-get remove --purge mbp-nvidia-bl-dkms
If you want to have a look, the sources are attached as well.
thanks & ciao,
Mario
