@jsalisbury #72 Samsung laptop NP300E5A-S07EE with double boot via wubi: Ubuntu 12.04 (32) W7 (64) I was getting flickering when I was trying to reduce screen brightness from max value (initial after installation) either via System Settings/Brightness and Lock, either via functional keys Fn+F2/F3. Either way I was unable to reduce brightness value below than ~80%. If brightness is left at max value, then I was able to use laptop until suspend. After returning from suspend flickering starts right away and indicator showed not max value that was set but ~80% brightness value. After kernel with commit reverted 9a2e71ce177a1602a0502fbcbb3f11e4bae584e4 installation, flickering effect not repeated so far, however: * with Fn+F2/F3 keys I still can't reduce brightness lower than ~80%; * I can reduce brightness trough Settings/Brightness and Lock but: * if I do anything with Fn+F2/F3 it goes back to max value; * if I again go to Settings/Brightness and Lock it switches to max brightness value right away; * if you return from dim screen it switches to max brightness value right away; * if I return from suspend it switches to max brightness value right away.

Again, I originally posted under Bug # 1028723, and was asked to test the latest v3.5 kernel, although the link http://kernel.ubuntu.com /~kernel-ppa/mainline/v3.6-rc1-quantal/ was to the latest v3.6 kernel. Since installing the mainline build, my issue has not returned. I am eager to report a successful test, but I am going to hold off for a bit and just leave my samsung laptop on for a little while. If the bug has not returned tomorrow, I will update this another report. Any idea on when this fix/patch/kernel update will become a part of a mainstream ubuntu update?
