Comment 10 for bug 784523

After updating the system to oneiric, the problem still exists -- flickering on the netbook display, but not on external display, but changed:
-- the flickering wouldn't occure anymore spontaneously;
-- the flickering occures, when I click on Display in the System Settings (behaviour similar as described for Bug #775088, worse than described for Bug #844235) or when I use the "encrease/decrease brightness" keys of the keyboard
-- I can't stop the flickering anymore (neither through right-click, Alt+Tab or Alt+Ctrl+Del nor through the Win-key [as described in Bug #844235 comment #5], Alt+Ctrl+F2 Alt+Ctrl+F7 [as described in Bug #775088 -- at least this has a little effect, the flashing is pausing or slowing down for a second])

In /etc/default/grub, I added "acpi_backlight=vendor" to the GRUB_CMDLINE_LINUX_DEFAULT parameters as described in comment #45 of Bug #810093, this didn't change anything.

Using the samsung-backlight package from https://launchpad.net/~voria/+archive/ppa as described in comment #26 of Bug #810093 helped: no flickering anymore, I can use System Settings > Display as well as the brightness keys to change backlight brightness just as I like. Thanks to Voria.
