Comment 242 for bug 568611

Hi Kamal,

Thanks for your work on the backlight issue.

It was working fine for me with your PPA, until I upgraded to 11.10 (Oneiric). Now it's back to the broken behavior - stuck at maximum, responds to the hotkeys (but only moves up or down a notch then jumps back).

I've tried various combinations of: acpi_backlight=vendor and dell_laptop.backlight=0 in 'grub' to no avail, including not putting them in there (rebooting after each attempt of course).

Here's my info:

Dell XPS 17 L701X (64 bit)

$ cat /etc/issue
Ubuntu 11.10

$ ls /sys/class/backlight/
