I have a problem that occurs roughly once every 90 minutes on a VM guest running Ubuntu 22.04.3 LTS.

  • System stops responding to any keyboard keypress or mouse click
  • Mouse movement still recognized
  • SSH and VNC still connect
  • The system can be interacted with normally via SSH
  • VNC Mouse clicks and keyboard keypresses are not recognized, but mouse movement is recognized
  • Virtual keypresses through VNC and VMware host controls eg. send ctrl+alt+del are not recognized
  • vmtools seems to be working properly, eg. changing the size of the guest window causes the windows inside the guest operating system to re-size

There isn't anything obviously using a lot of resources and apart from not being able to click or type, the system seems to be running without problem.

I've tried:

So far the only thing that re-enables keypresses and mouse-clicks is rebooting the guest VM.

The host is running Windows 11, with VMWare Workstation 17

 

Is there a way to recover mouse & keyboard control without restarting Ubuntu, or a way to prevent the issue from re-occurring?

It just sounds that the guest os doesn't have much memory allocation size. If possible, raise the RAM size it provided.
