# [Linux only] Black screen

${color}[#676767](**If you are having a black screen when using Drovio on Linux, here is how to fix it.**)


### What to do if there is a black screen when the session's Host is sharing the screen?

###### If only the guests are getting a black screen 

* You are probably trying to share a high resolution screen (>= 4K) and your machine can't handle it. We generally detects that and fall back to voice chat with a notification. There are some cases however where we can't prevent it.


###### If both, the session's host and the guests are getting a black screen 

* This means that the host's desktop environment does not support transparency. Since our application is using on-screen overlays, a compositor is necessary in order to render transparency and prevent the black screen. 
* To solve the issue the host needs to install and run the compositor manually, for example, if the host is using i3 (window manager), they will need to `apt install picom`  and run `picom&`.
* The 3 main free compositors are: **Compton**, **Picom** and **Xcompmgr**.
