I did a clean install with updates of Gutsy x86_64 on a new Sony Vaio VGN-NR160 laptop. Screen backlight control is non-functional from both the gnome desktop applet and the brightness applet on the launcher panel. "lsmod" show the sony-laptop module is loading. I have only a generic directory "acpi_video0" in /sys/class/backlight, nothing for "sony". Echoing values in to "brightness" does nothing. I do have an empty directory in /proc/acpi/sony if that means anything.
I am compiling kernel 2.6.23.12 now. We'll see if that does anything. Otherwise I think I'll have to drop back to a 32-bit install. I haven't tried the 32-bit live cd yet. I'll try that first. -- [regression] gnome-power-manager laptop backlight not working on VAIO VGN-FSxxx https://bugs.launchpad.net/bugs/152731 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
