It works with Macbook 5,1 and Lucid Lynx, but the adjustment is very slow if I install pommed too.

Well, I uninstalled nvidia-bl-dkms, rebooted, and reinstalled mbp- nvidia-bl-dkms, and... surprise, it worked indeed!

[Bug 516354] Re: nvidia-bl-dkms 0.15.1 update breaks backlight
@WindPower: This isn't relevant, since you installed both drivers nvidia-bl-dkms and mbp-nvidia-bl-dkms. (If you didn't install the latter from the mactel repo, the version provided by the linux kernel should also have been sufficient.) However, until nvidia-bl 0.15.0 nvidia-bl didn't auto-load. mbp-nvidia-bl always does. So, if you added a line to /etc/modules for nvidia-bl, you ended up loading both drivers providing two interfaces in /sys/class/backlight. Furthermore, if the brightness keys didn't work, HAL has just used the wrong interface. As of nvidia-bl version 0.15.1, I got auto-loading to work. That also means the package now installs a file in /etc/modprobe.d, that blacklists mbp-nvidia-bl. That's why your scripting approach doesn't work anymore - the driver you used is just missing. Finally, for some strange reason nvidia-bl doesn't work on some MacBook Pro 5 models. Probably those incorporating two graphics adapters. But due to a lack of information, I don't really know. That means, if you can confirm that nvidia-bl doesn't work (as you did), just deinstall it. There's no reason to have both drivers installed. Unfortunately, mbp-nvidia-bl is also known to not work on some Apple machines. That's why there are both in the repos. Btw: They aren't completely redundant. While nvidia-bl (in theory) should support a wide range of machine incorporating Nvidia graphics adapters (not just from Apple), does mbp-nvidia-bl only work on Apple machines. In contrast to his name, not just MacBook Pros with Nvidia graphics, but all models incorporating Intel processors. -- nvidia-bl-dkms 0.15.1 update breaks backlight https://bugs.launchpad.net/bugs/516354 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I am experiencing this bug, both with the 2.6.31-19-generic and 2.6.31-17-generic kernels. I am, however, able to adjust the screen brightness using the F1 and F2 brightness buttons (pushing them without holding down the fn key). The problem however is that the brightness increments or decrements very, very slowly and in tiny amounts. Earlier releases had much larger increment and decrement amounts, and were much more usable. Can we please get back these old values for the brightness increment/decrement? -- nvidia-bl-dkms 0.15.1 update breaks backlight https://bugs.launchpad.net/bugs/516354 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hello, seen the same problem in Karmic with nvdia-bl-dkms 0.15.2 The install procedure (via synaptic or aptitude) fails when building the module, when searching for : /usr/src/nvidia_bl-0.15.2.dkms.tar.gz The package seems correctly installed to synaptic though it doesn't work anymore (no OSD slider, no effect on screen backlight). It seems that it's just a matter of packaging : like the source file has been forgotten at ship time or some stupid reason like this :-) -- nvidia-bl-dkms 0.15.1 update breaks backlight https://bugs.launchpad.net/bugs/516354 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
