Comment 78 for bug 644898

Thank you Solnyshok for the information, and also keks-n for the pre-compiled module. It also works for me.

Actually I found it is not necessary (at least in my case) to create the "extra" folder and copy the toshiba_acpi module into it. All I had to do was copy the modified toshiba_acpi.ko to /lib64/modules/2.6.38-*-generic/kernel/drivers/platform/x86. Then remove the old module (rmmod) and start the new one (modprobe). All done!

To Alex:
Once you have toshset working (see above), to use the trans-reflective mode just use the following command:

To turn trans-reflective on:
sudo toshset -trmode on

And to turn it off again:
sudo toshset -trmode off

There might also be a way to activate the special button above the keyboard. You might find that once toshset is working your script might work again :)
