Bug not present if I boot with last 10.04 kernel, which was left as an option in my Grub menu. Reassigning to Linux as a kernel issue.
** Package changed: acpi-support (Ubuntu) => linux (Ubuntu) ** Tags added: apport-collected ** Description changed: Binary package hint: acpi-support After an upgrade to Ubuntu 10.10 the previously natively-supported Fn key control of backlight brightness is gone. I can control backlight with xbacklight, as before. This seems to be a regression, related to bug #173652.
