I am running lubuntu:
lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.5 LTS
Release: 18.04
Codename: bionic
as Guest OS under VirtualBox
VirtualBox Graphical User Interface Version 6.1.16_Ubuntu r140961
with guest addition installed.
And within this VM I have the same problem both with VICE (x64, the C64 emulator) and FS-UAE, the Amiga emulator.
In both cases, the mouse is not captured correctly. In VICE (for example, trying out GEOS) the mouse pointer does not move at all (I have tried several solutions found in the internet), in FS-UAE it behaves erratic: Seemingly x and y axis are exchanged and it is far too fast, i.e. it jumps wide distances from tiny mouse movements.
It seems to me that this is either a VirtualBox-Problem or a Lubuntu-Problem. I cannot tell.
I have searched for answers, and found one similar problem under another Distro concerning the DosBox.
that does not provide a solution to me, and a list of mouse problems in Ubuntu, but not exactly this problem, here:

Perhaps relevant (?) in this contex: Currently, this VirtualBOX does not support USB higher than USB 1.1 (i.e. it cannot start the guest OS if one configures, e.g., USB2.0). This will hopefully disappear with the next update, and I do not know whether this failure is connected to this fact.
So here is the question: Does anybody have experience or even a solution with dysfunctional mouse capture unter Lubuntu (especially 18.04) in a VirtualBox (especially 6.1) or any VM environment?
Thanks in advance!
