The link @zabadabadoo posted relates to the same issue that was previously present in the non-Lite (Gnome Shell) editions of Zorin OS, and was fixed in a software update soon afterwards. However, it doesn’t have any effect on Zorin OS Lite.
Based on our preliminary research, it looks like the way XFCE handles the Super (logo) key shortcut (which is mapped to the Zorin Menu by default in Zorin OS Lite) can interfere with other keyboard shortcuts that begin with the Super key on some systems. We’ve added it to our roadmap to fix this issue in Zorin OS Lite, so this shouldn’t be an issue in the future.
In the meantime, the easiest workaround would be to disable the Super key shortcut to open the Zorin Menu by following these steps:
- Open the Zorin menu > Settings > Keyboard > Application Shortcuts
- Scroll down the list to select the “xfce4-popup-zorinmenulite” item
- Press the “Edit” button to change the keyboard shortcut, or the “Remove” button to delete it entirely
This should have enabled the other Super+ keyboard shortcuts. These shortcuts include Super+Left/Right to tile the active window to the left/right of the screen and Super+number to open the numbered app from the taskbar.
Alternatively, if you’re a more advanced user and wish to keep the Super key shortcut for the Zorin menu as well as the other Super+ shortcuts, one of the following tools might help you with this:
- GitHub - hanschen/ksuperkey: Linux utility that allows you to use the Super key both to open the start menu and as a modifier key in keyboard shortcuts
- GitHub - alols/xcape: Linux utility to configure modifier keys to act as other keys when pressed and released on their own.
- GitHub - jixunmoe/xfce-superkey: Linux utility that allows you to use the Super key both to open the start menu and as a modifier key in keyboard shortcuts
The default keyboard shortcut to show the desktop in Zorin OS Lite is Ctrl+Alt+D. If you wish to set Super+D to show the desktop, please follow these steps:
- Open the Zorin menu > Settings > Window manager > Keyboard
- Scroll down the list to select the “Show desktop” item
- Press the “Edit” button below the list
- Press Super+D to set this as the keyboard shortcut
