The Fedora fix seems much more elegant and less invasive by simply finding
and eliminating a software keymapping duplicate of hardware/bios activated
keys, if it's the same issue! Maybe it's part of the fix, because the

Adam, I think you issue with pause/next/prev buttons is something
different. Because everyone in this thread has problem with brightness

I have such a model and I keep seeing double changes in brightness when

increments,
Sounds like this can be considered fixed on the Dell laptops now, for

Users of non-Dell laptops who are experiencing similar symptoms should
file separate bug reports (preferably, after checking whether the
problem still affects them with Ubuntu 9.04).
