I can confirm that brightness control still is'nt working on my 12 powerbook with ubunti edgy fully updated as of today. Using Fn+F1/F2 I just get the shiny gtkpbbutons slider to move but with no effect whatsoever on display brightness. Using fblevel I get this error message: ioctl PMU_IOC_SET_BACKLIGHT: No such device
It should be noted that with gentoo linux on the same laptop brightness control works perfectly with gentoo-sources (any version from 2.6.14, the first I tried). If needed I can post my gentoo .config -- brightness controls not working for 12" powerbook https://launchpad.net/bugs/35992 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
