This bug also affects me with 12.04. I have a Dell E6520 with
Intel+NVidia (optimus). I see different timings than Sparhawk
This happened both with a fresh installation, and after installing
bumblebee. In both cases optimus was ON in the bios, but in the former
case the system was falling back
I have the same problem on a E6520 with an Intel Graphics card

Title:
Adjusting display brightness is very slow
Also, I just thought someone should quantify *how* slow it is. I just
timed it, and it takes 25 seconds for the button presses to register
(for the internal keyboard, as I mentioned previously).

I have this too, with Ubuntu 11.10 on a Dell XPS 17 L702X. I'm running
Bumblebee for the graphics driver.
What is *very* odd is that the brightness keys are very slow if I use the
internal keyboard, but they work immediately if I use my external keyboard (a
wired Apple aluminium keyboard).

Same here, running Ubuntu 11.04 on a Dell XPS 17 (a.k.a. L702x) with a
Nvidia GT555M (without optimus).

Title:
Adjusting
Hi Mathieu,
Thanks for the reply.
I just guess there is a general issue with Dell systems.
There might be an issue with the kernel, or the gnome-power-manager.
The issue never happened on different OSes with lower kernel revisions like
Fedora 13, 14 and Centos AND RHEL 5 and 6.
Also, Solaris
