Hi,
I am new to nixos. I managed to install and run nixos (latest) as vmware guest. However, my mouse integration doesn’t seem to be working, i.e. I need to press ‘Ctrl+Alt’ to release mouse if I want to move out.
More importantly, ‘Fit guest now’ option is greyed out. I have enabled `virtualisation.vmware.guest.enable = true;` in my configuration.nix however that doesn’t seem to solve the issue. Any pointers?
Warm regards
Bikal

I import this into my VMs and it works without any further configuration:
```auto
{
virtualisation.vmware.guest.enable = true;
}
```
Unless I am missing something, that is exactly what you have already.
Which DE/WM are you using? How complicated is your configuration.nix, is it possible there is something strange going on in there? Can we see it?

I’m having the same issue with auto-fitting/resizing as @bikallem and @megapro17. Guest tools (aka open-vm-tools) are installed and running, as confirmed by `systemctl status vmware.service`, and I did make sure to add enough video memory to my VM as per [open-vm-tools does not resize the display on Ubuntu 15.04 · Issue #54 · vmware/open-vm-tools · GitHub](https://github.com/vmware/open-vm-tools/issues/54#issuecomment-233053305) . However “Fit guest now” remains grayed out and the screen resolution does not adjust automatically.
What I noticed, though, is that `xrandr` will output a different “preferred” resolution (marked with the plus +), depending on the VM’s window size. It just doesn’t switch to that resolution automatically. Running `xrandr --output
