===== Jittery Mouse in VMWare for Linux Guest =====
This was driving me crazy.  My mouse was constantly flickering as I'd move it around the screen in my Linux (Ubuntu 20.04) guest.  The VMWware help for this was also utterly useless:  Install vmware-tools (really ''open-vm-tools'').  I finally came across some older posts on Linux forums saying that turning off "HWCursor" in ''xorg.conf'' did the trick and, spoiler alert, that worked.

==== The xorg.conf File ====
All you need to do is drop this file in ''/etc/X11/'' and reboot (or restart X) and you should be good to go.  If your distro ships with an xorg.conf (Ubuntu 20.04 does //not//), you can just add the ''"HWCursor" "Off"'' lines to your existing file.:

<file xorg.conf xorg.conf>
Section "Device"
        Identifier      "Configured Video Device"
        Option          "HWCursor" "Off"
EndSection

Section "Monitor"
        Identifier      "Configured Monitor"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        Device          "Configured Video Device"
        Option          "HWCursor" "Off"
EndSection
</file>
