Comment 17 for bug 295251

I installed Hardy (8.04.1) using the Alternate installer and I had to use acpci=off as a boot option to install Ubuntu. I noticed that when I used this boot option the brightness keys such as the up and down arrow, but also the FN+F5 key worked as expected. Perhaps this info can help us further determine the issue and solve it? Feel free to contact me for more info if this is needed. I'm willing to test and check things.
