Recently I bought an iBook G4 and installed Linux on it. I am using linux-2.4.23-ben1 and have the following problem: When configured with CONFIG_PMAC_BACKLIGHT=y, on startup the screen switches completely off (it took me some time to notice that the kernel does not crash but only the screen turns dark and the system keeps booting). To get in control of the keys at the top of the keyboard (for adjusting sound, the lcd backlight and ejecting the cd drive), I installed pbbuttonsd so I now can influence the lcd backlight and tune it up again. But the minimum and maximum brightness does not seem correct. The screen switches off to early when darkening or lightening the screen. The direction (up and down) seems to be inversed. When pressing the up key, brightness goes down. I am sure the correct keys are configured in /etc/pbbuttonsd.conf. Is it possible that someone looks into this? I am not a kernel hacker, but I can help with testing and answering any questions you should have. Thank you! Roland ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
