Comment 5 for bug 56639

This bug was closed invalid over three years ago due to lack of available information. If you have new information to add, please add it - otherwise, please leave the bug state alone.

Note that the ThinkPad Fn+F7 button has been working reliably via udev + gnome-settings-daemon for a while now, so even if you are experiencing problems currently, it is unlikely to be a bug in acpi-support and you should probably open a new bug report.
