Guest issues

This section covers issues you might have running NixOS as a guest VM in VMware Workstation or similar.

Display issues

Cannot change resolution in KDE Plasma ISO

If you are unable to change resolution in a guest VM while booted into the NixOS Plasma graphical installer ISO...

This appears to be an issue where if KScreen is running as a service it will instantly revert to the default resolution [1].

Disabling the KScreen 2 Service under Background Services allows resolution settings to apply properly.

If you continue to have issues, running journalctl should print a system log with debug info which might help in resolving the issue.

Mouse issues

Mouse buttons above 5 do not work

If your mouse's thumb buttons or other additional buttons do not work, set guest to use advanced mouse. For your NixOS-based guest VM, add the below lines to its .vmx configuration file:

 mouse.vusb.enable = "TRUE"
 mouse.vusb.useBasicMouse = "FALSE"
