Thanks kamal for your work on this. I had this issue on Dell 1558 on ubuntu 11.04. I updated to your patch. I thought this was fixed on 11.10, I updated my system to 11.10 yesterday and now my brightness doesn't work anymore :(. The applet shows the bar but notthing happens on the screen. When I grep the "dmesg" I see following errors:
[ 15.312411] [Firmware Bug]: ACPI: No _BQC method, cannot determine initial brightness Can you please let me know if you can release a patch for this or if there is other workaround.
