[Alex]

Binary package hint: toshset

The whole problem is that my birghtnes keys don't work on my laptop! Its a toshiba t135. They worked fine on 10.04 with "nomodeset acpi_backlight=vendor", but this now drops me to a terminal with the following error:
/etc/rc2.d/S99acpi-support: line 7: /usr/share/acpi-support/power-funcs: No such file or directory

launching toshset (Toshset is a command-line tool to allow access to much of the Toshiba laptop hardware ) outputs:
required kernel toshiba support not enabled.
