    Was able to launch a Debian instance fine, but today when I launched it cursor disappeared, I'm not able to control the window, I'm not able to use keyboard.

    it just says to press ^ alt or something to reenable cursor. When I press it, it gives me cursor to control host OS, but there is no way to control the virtual machine anymore.

    What happened? Everything was working fine and I made no changes or updates to the system. I don't want to reinstall since I have valuable data there.

    I'm not going to send sensitive technical data on a public forum.
    I installed a new Debian instance and it works fine.
    I restored default settings in old Debian instance. It still doesn't recognize the mouse.
    I tried "optimize for gaming", no luck.
    I have all the settings and configs on that instance and have to access it and can't.
    How do I copy the contents, settings of Linux OS and run it in a new instance? I don't want to reconfigurate everything

    For some reason the virtual machine "captures" the mouse yet doesn't display it. I don't understand why it started doing it. The other (newly created) virtual machine works fine without "capturing anything". So when Debian "captures" mouse and keyboard I have to click ctrl + alt to "release" it.

    Hello,

    Thank you for your feedback.

    As a workaround, you can also try the steps below:

    It requires modifying a GRUB system boot file, so it's highly recommended to back up your virtual machine or creating a snapshot before proceeding.To apply the workaround, please perform the following steps:

    1. Start your virtual machine.

    2. Create a Snapshot of the virtual machine before proceeding by clicking on Actions -> Take a Snapshot.

    3. Open Terminal, and execute the following command:
    Note: You will have to input your administrator password to execute it.

    sudo nano /etc/default/grub

    4. Scroll down and locate the line:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet"

    5. Replace that line with the following line:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet xhci_hcd.quirks=0x40"

    6. Take screenshot before saving.

    7. Press "Control+X" -> press "Y" -> press "Enter".

    8. Next, execute the following command:

    sudo update-grub

    9. Check if the mouse issue persists.

    If the issue persists, please provide us with the following data:

    1. Please collect an additional technical report (click on the Parallels Desktop icon > Help > Send technical data > check "Attach screenshots..." > press Send Report) and send the report's 9-digit ID in a reply to this e-mail.

    2. A screenshot of the modified grub file from step 6.
