Adam, thanks for the follow up. Let this report focus on 1), and 2) can be pursued via separate report targeted to lightdm.
Despite this, when you boot up with the computer in the docking station, are there any crash files in /var/crash? ** Description changed: Laptop works perfectly when not docked. If I boot when in the dock, the logon screen is highly corrupted. I can enter my username and password anyway and then it logs me in, I can see the screen on the external display, and everything works EXCEPT my mouse pointer is invisible! I can move the mouse around and if I get it in the right place (for example, I can get to a corner) and click it works, so the OS "knows" where the mouse pointer is but I just can't see it. + If I boot up and log in with the laptop undocked, and then place in the + dock, everything works perfectly. - If I boot up and log in with the laptop undocked, and then place in the dock, everything works perfectly. + The display corruption issue was resolved by swapping in an HDMI cable + for the VGA cable.
