Comment 118 for bug 644898

I've just attempted to use the 'raring' version of the toshiba-acpi-fix package from https://launchpad.net/~keks9n/+archive/main

I was impressed to find that against one of the kernels in my Ubuntu Gnome Saucy (13.10) the kernel 3.9.0-7 the patched toshiba_acpi does indeed build and function, and although the hardware button doesn't work, I can turn on transflective mode from the command line with...
sudo toshset -trmode on
and back off with...
sudo toshset -trmode off

Sadly, with either of the 3.11 kernels (also installed) the build fails, and below is a typical error from the build process...
