#15527 duplicate Mouse Cursor Hidden -> duplicate of #7945. kingbeandip
Description

On my machine the mouse cursor is invisible (clicking, hover events, dragging, etc all work, but I cannot see the cursor) when the VM captures the mouse. This happens both when Mouse Integration is turned off, and when I attempt to assign a second mouse to the VM (in the Devices menu). Mouse integration works normally, but this prevents me from dedicating a mouse to the VM.

I am using an Intel i5 processor, and Linux Guest Additions are fully installed and working. 3D Acceleration is enabled. The problem is extremely finicky when Acceleration is disabled, and I have been able to get the mouse capture to work until I reboot the VM. I have never been able to get it to work with acceleration enabled, though it does depend slightly on the guest.

Host: Windows 10 Pro Guest 1: Ubuntu 16.04 (captured mouse always invisible) Guest 2: Ubuntu 16.04 with Cinnamon 3 GUI (captured mouse always invisible) Guest 3: Kubuntu 16.04 (captured mouse only invisible when mouse integration is turned on)

Other information: This problem is not new to VirtualBox 5.0.22. I have also seen in forums some people comment about this problem in VirtualBox 4.x, but the bug was supposedly resolved.

#15526 duplicate Guest additions newer than 5.0.16 cause X to fail in Ubuntu 15 and 16 -> duplicate of #15860 raynebc
Description

As reported on the forum a couple times, most recently here: https://forums.virtualbox.org/viewtopic.php?p=364318#p364318

In that thread, Michael indicated Oracle can no longer can reproduce the wide spread problems where the newer versions of the guest additions (newer than 5.0.16) caused the video interface to not launch in some versions of Linux, so he asked me to open this ticket.

(Edit (Michael): I am not aware of these "wide spread problems" at all, let alone able to reproduce them.)

My host OS is Windows 7 Pro x64 and the affected guest OSs are Ubuntu 15.x and 16.04 LTS. Originally I just grabbed the generic Ubuntu 15.10 VM image from osboxes.org and installed some various packages mostly just related to building a cross-platform application that I program for. The Ubuntu 16 VM was created by making a clone of the Ubuntu 15 VM within the Virtualbox manager and allowing the OS to upgrade to Ubuntu 16.

I will attach two sets of logs. One of them is a normal boot and shutdown while the version 5.0.16 guest additions are installed. The other set reflects the botched boot up when the 5.0.22 guest additions are installed and me manually opening a virtual terminal to issue the shutdown command.
