I recently hooked-up a second monitor to an Nvidia GEFORCE GTX 1060. When I am using my primary monitor, the secondary monitor shows the cursor as well.
My monitor setup:
- Left monitor portrait _____ 1200x1920 (secondary)
- Right monitor landscape __ 1920x1200 (primary)
with the Ubuntu desktop.
In particular, when my cursor is in the top-left 1/6th of the primary landscape monitor, I see the cursor in the bottom-left 1/6th of my secondary portrait monitor. But, if I am in that same bottom-left 1/6th of the secondary portrait monitor, I do not see it in the primary landscape monitor.
Note: I have already tried using the proprietary and Nouveau open-source driver, and this unfortunately did not solve the issue.
