Bug Description
With LMDE installed on a SAMSUNG NC10 PLUS athe graphical desktop begins to flicker, as soon as the system seems to be ready for the user.
Switching to the console area shows: ACPI: Failed to switch the brightness.
After returning back to the graphical screen, the brightness is stable (of course darker than before), but can be manually adjusted.
Switching to the console (CTRL+F2) and back again results in a darker graphical screen again (altough manually adjustment still possible).
uname - a: Linux mint 2.6.39-486 / Gnome / 32-bit
When does it appear: As soon as the system has been started.
Reproducable: yes

Thank you for taking the time to report this bug and helping to make Mint better. This particular bug has already been reported and is a duplicate of bug 810093, so it is being marked as such. Please look at the other bug report to see if there is any missing information that you can provide, or to see if there is a workaround for the bug. Additionally, any further discussion regarding the bug should occur in the other report. Feel free to continue to report any other bugs you may find.
Ps. Mint is based on Ubuntu so I marked this as a duplicate of the Ubuntu bug which is currently fixed. If you still have flickering issues, then I suggest you to follow bug 919773 and mark that bug as affecting you.
