For me, the LED also won't work, but I don't have a dell-
laptop::touchpad/brightness file under /sys/class/leds/.
I'm running Precise with kernel 3.2.0-49.

I submitted the 2 patches mentioned in #6 to stable kernel,
so they will go into precise kernel at next merge.

AceLan;
Are you still planning on providing those as SRU? What is there left to
be done to fix this issue?

Touchpad LED on Dell's laptop
Hi,
In Precise kernel, it already provided an interface to turn on/off the
tourchpad LED
/sys/class/leds/dell-laptop::touchpad/brightness
Other patches are just quirks to add more machines to have this
interface, so I don't think it's so urgent.
The problem is that there is no userspace app
Yes, I'll submit SRU to the kernel team to cherry pick those patches.
But, we still don't have a good way in userspace to cooperate with the kernel
driver.
It just comes to my mind, maybe ubuntu kernel team will accept the way turning
on/off touchpad LED in the driver until we have a better way
Maybe, we could get the following upstream commits into the Ubuntu
kernel?
dell-laptop: touchpad LED should persist its status after S3

Indeed user processes cannot, and should not be able to, change sysctls.
First, they do not have the necessary privileges, and second, if you
have multiple users logged in at the same time, they would all try to
set the value concurrently, possibly to different values.
The usual approach to this

I fixed the problem to persist the LED status after S3 in the driver, but I
still have no idea how to let user space application access the sysfs without
root privilege.
And I don't think it's suitable to change the file mode to 0666, for I can't
find any file with that mode in sysfs.

Hi,
I'm trying to build a patch for this issue, but I encountered some
problems.
1. The permission of the file in sysfs is 0644, so gsd(gnome-settings-daemon)
should have root privilege to access the file.
