I'm having the hardest time getting the pointing stick to work on my D620. From what I understand, the pointing stick is supported on some Dell and Lenovo models by the current version of RehabMan's VoodooPS2 driver (2018_05_06 v1.8.34) that I have installed. However, it doesn't seem to support the D620, as neither my pointing stick nor their mouse buttons work at all. The pointing stick seems to respond right as I come to the login screen after I boot up, but only by wildly jumping the cursor all over the screen. After I log in, it stops working altogether.
