Updated from Ubuntu 13.10 to 14.04. Keyboard input is sluggish. When typing one letter appears after I type the next one.
While changing brightness using fn + brightness key notification appears but the brightness change after a long time or does not change at all. I am using a Lenovo ThinkPad L430.
Note: I did not have any such problem with Ubuntu 13.10 or previous version in the same laptop.
