I used Ubuntu gnome. In Ubuntu, I could share the clipboard between
the windows-host and the ubuntu-virtual machine without any issues.
First, restart the Guest machine (this ensures a good starting point for the next installation step). See if the Clipboard copy / paste has returned.
In the VMware Menu, Go to VM, and then select Reinstall VMware Tools.
See this screen shot to help you.

If the option to reinstall is greyed out, then you need to install the Tools manually. This may also be needed in the case for "i3" . Ubuntu Tools install on a modern version is automatic.
Manual Tools Install
Power on the virtual machine.
Verify that the guest operating system is running.
Because the VMware Tools installer is written in Perl, verify that
Perl is installed in the guest operating system.
Select the menu command to mount the VMware Tools virtual disk on the
guest operating system.
In the virtual machine, open a terminal window. Run the mount command
with no arguments to determine whether your Linux distribution
automatically mounted the VMware Tools virtual CD-ROM image.
If the CD-ROM device is mounted, the CD-ROM device and its mount point
are listed in a manner similar to the following output: /dev/cdrom on
/mnt/cdrom type iso9660 (ro,nosuid,nodev)
If the VMware Tools virtual CD-ROM image is not mounted, mount the
CD-ROM drive. If a mount point directory does not already exist,
create it.
mkdir /mnt/cdrom
Some Linux distributions use different mount point names. For example,
on some distributions the mount point is /media/VMware Tools rather
than /mnt/cdrom. Modify the command to reflect the conventions that
your distribution uses. Mount the CD-ROM drive. mount /dev/cdrom
/mnt/cdrom
Some Linux distributions use different device names or organize the
/dev directory differently. If your CD-ROM drive is not /dev/cdrom or
if the mount point for a CD-ROM is not /mnt/cdrom, modify the command
to reflect the conventions that your distribution uses.
Change to a working directory, for example, /tmp. cd /tmp
(Optional) Delete any previous vmware-tools-distrib directory before
you install VMware Tools. The location of this directory depends on
where you placed it during the previous installation. Often this
directory is placed in /tmp/vmware-tools-distrib. List the contents of
the mount point directory and note the file name of the VMware Tools
tar installer. ls mount-point Uncompress the installer. tar zxpf
/mnt/cdrom/VMwareTools-x.x.x-yyyy.tar.gz The value x.x.x is the
product version number, and yyyy is the build number of the product
release.
If necessary, unmount the CD-ROM image. umount /dev/cdrom
If your Linux distribution automatically mounted the CD-ROM, you do
not need to unmount the image.
Run the installer and configure VMware Tools as a root user cd
vmware-tools-distrib sudo ./vmware-install.pl
Usually, the vmware-config-tools.pl configuration file runs after the
installer file finishes running. If you attempt to install a tar
installation over an RPM installation, or the reverse, the installer
detects the previous installation and must convert the installer
database format before continuing.
Note: For newer Linux distributions, users are prompted to choose the
integrated open-vm-tools.
Follow the prompts to accept the default values, if appropriate for
your configuration.
Follow the instructions at the end of the script.
Depending on the features you use, these instructions can include
restarting the X session, restarting networking, logging in again, and
starting the VMware User process. You can alternatively reboot the
guest operating system to accomplish all these tasks.
