Keyboard or mouse do not work in a hosted virtual machine

Posted on Updated on


To troubleshoot a misbehaving mouse or keyboard:
  1. Confirm that the virtual machine guest window currently has focus by clicking into the virtual machine’s console window. Keyboard or mouse input is only directed to the virtual machine when it has focus or is in full-screen mode.
  2. If your mouse is slow to respond or if it is working erratically, change the optimization settings. For more information, see Mouse movement is not smooth in a hosted virtual machine (1033416).
  3. If you are using a wireless mouse or keyboard, ensure that you have not connected it to the virtual machine by removing and re-adding the USB Controller from the virtual machine. For more information, see the Workstation Help topic Add a USB Controller to a Virtual Machine.
  4. Restart your host computer.
  5. For Windows hosts, use the Windows System Configuration (msconfig) utility to eliminate software and processes as possible causes. For more information, see Using the Windows System Configuration utility (1004010).
  6. For Linux hosts, start Linux in a mode that disables start daemons (typically run level 2; if your host lacks this, you may need to start in single-user mode). For more information, see Changing Linux run levels (1004015) or your operating system documentation.
    Note: These next steps require a second mouse/keyboard. For more information, see Connecting a second mouse or keyboard directly to a hosted virtual machine (1033435).
  7. Look for non-Microsoft, non-VMware mouse/keyboard drivers or software installed in the virtual machine, and remove them.
  8. Re-install VMware Tools. For details, see Overview of VMware Tools (340).
