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.
Hope this information is useful.
