Axis transform

I have Blender 2.73 under Ubuntu 14.10, and once i launched it i found that i can’t drag, scale or rotate object around using XYZ arrows (or whatever it becomes when you switch transformer). One mouse button just set cursor (i set it to right one), other just drag it around, like when you press G without XYZ buttons. Same with scale\rotate selected. Yes, it works using G\S\R - X\Y\Z shortcuts, but some times i’d better just drag it with mouse, you know. Changing L\R mouse buttons won’t help.
And less important, but does anybody knows how to place blender icon on ubuntu launcher?
