I've got the same problem on the chinese notebook Haier A61, running Ubuntu 8.04.
The brightness-up-key (Fn+F7) does not produce an event - none of the methods described in https://wiki.ubuntu.com/LaptopTestingTeam/HotkeyResearch work. However, the brightness-down-key (Fn+F8) produces an event and causes the OSD to appear. The brightness level doesn't change, though. All other Fn-Keys work (sleep, switch to ext.display, volume up/down). When switching to an external display and switching back to the internal LCD, the brightness OSD indicates full brightness again. The brightness doesn't change. When the backlight should dim according to power management settings, the screen actually just fades to black but stays lit. The actual brightness of the display is pretty bright. I've noticed that the output of cat /proc/acpi/video/VGA/LCD/brightness just yields "<not supported>". I think I've had no problems in earlier versions of ubuntu. -- Fn keys on VAIO VGN-NR230 don't produce ACPI events https://bugs.launchpad.net/bugs/251665 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
