Hi everyone. Ever since upgrading to Ubuntu 12.04 I had the issues listed in the original bug description (heavy flickering for prolonged time, eventually stopping at lowest brightness, whenever the brightness was changed automatically or manually).

I just installed
linux-image-3.2.0-29-generic_3.2.0-29.46~lp1028151v2_amd64.deb
from comment #49 above and ever since the problems are gone and I can use FN+F2 FN+F3 to change brighness. No other ill side effects / regressions are known. The Laptop is a Samsung 90X3A:

sudo dmidecode|grep -i "base board information" -A3
Base Board Information
 Manufacturer: SAMSUNG ELECTRONICS CO., LTD.
 Product Name: 90X3A
 Version: FAB1

Best Regards
Michael

PS: anything else I can help with?
