  • 1.  WS 17.6.1 keyboard lag with Ubuntu guest

    Posted Oct 22, 2024 05:31 PM

    Upgrading to WS 17.6 and then 17.6.1 from 16, I had a noticeable keyboard lag in the VMs on W11 23H2 in a Ubuntu 20.04 guest with open-vm-tools installed under XFCE4. The keyboard lag could also be multiple seconds with excessive repeats.

    Adding only this single line to the VM's .vmx file resolved the topic for me:

    keyboard.vusb.enable = "TRUE"

    Now the keyboard response is as snappy as before.

    Update: It appears to be *MUCH* better to not use the vusb option, but to enable “Virtualize IOMMU (IO memory management unit)” in the Processors settings of the VM, per feedback from other users.

    Hello, 
    I think I'm experiencing the keyboard lag and I'm trying to fix this. The 1st thing you said to do is not working for me. I'm looking for where to enable "Virtualize IOMMU" but I can not find this in the processor settings. The only settings I see are "Virtualize Intel VT-x/EPT or AMD-V/RVI" or "Virtualize CPU performance counters".

    Works! Thanks so much! I have been using the keyboard.vusb.enable = "TRUE" fix for a while now (Windows 11 host, VMWare Workstation 17.6.x, Ubuntu Server 24.04 guest) but it was imperfect. Instead of the massive buffering and repeating letters, runaway cursor, etc. that it did without it, it would still occasionally require double key presses, and had random stutters. Definitely better than without it, but still not that great.

    I implemented your suggested fix (after removing the line mentioned above from the .vmx file) and, so far, typing into the guest is exactly like it was installed on bare metal, no keyboard problems whatsoever. Thanks again!

    Unfortunately, enabling "Virtualize IOMMU" didn't do the trick for me.

    `keyboard.vusb.enable = "TRUE"` kinda works but it's still not great. The delay seems to be mostly gone but typing still feels... off for a lack of a better word.
