Emulate 3 Button Mouse not working on Satellite laptop The Emulate 3 Button Mouse feature doesn't work as described. ALT+LMB causes the entire Blender window to resize and then move in tandem with the motion applied to the mouse-pad. Is there any additional setting beyond clicking the Emulate 3 Button Mouse box that must be set correctly in order for this feature to work?

A. When you say, "conflicting keyboard shortcut," do you mean a shortcut in Blender itself, or something universal I may have done with my laptop? I have not intentionally set up ANY shortcuts yet in Blender.

B. If I understand you correctly, the Blender window does indeed resize itself and move whenever I use ALT+LMB, regardless whether Emulate 3 Button Mouse is checked or unchecked. There is another checkbox directly below Emulate 3 Button Mouse named, Continuous Grab. The problem also remains the same regardless whether Continuous Grab is checked or unchecked.

C. I don't know what ALT-Drag is. I am running Ubuntu on a Satellite laptop.
The reason this is happening is because Alt+LMB is the Ubuntu/Linux shortcut to move a window around. You may be able to circumvent this by using super+alt+LMB depending on your version of Ubuntu.
