## VNC: shadow `shadow` allows for simplified VNC Screensharing between Thinlinc sessions and flips. - Start "Shadow Screenshare" from the applications menu, a system tray icon will appear. (Bottom right on Thinlinc, top right on laptops & flips.) [![shadow_icon_screenshot.png](https://wiki.math.uzh.ch/public/uploads/images/gallery/2026-06/shadow-icon-screenshot.png)](https://wiki.math.uzh.ch/public/uploads/images/gallery/2026-06/shadow-icon-screenshot.png) - Left click on the icon and choose either 'View' or 'Share with', a text box will appear where you can enter an ID. Real world examples: - Click 'View', enter `crose` to shadow a colleague with that username. They get a popup asking for permission. - Click 'Share', enter 'enured' to share your screen with a colleague with that username. They'll get a popup asking if they want to see your screen. If they accept, it'll *again* ask you if you actually want to share your screen with them. - Click 'Share', enter a room number like `k11` or `k30` to *project* your screen to a flip nuc. These are configured to accept shares by default, so you'll get a view request right back. - A list of all your recent actions is kept, so you don't have to type your colleagues name each time. Simply select an action from the tray icon's menu. - To disconnect all connected clients, there's a button above the `Quit` menu in the tray icon's menu.
