If you run into some issues when using Splashtop with Linux, have a look at our most frequently asked questions below to find some answers.
Why do I get a black screen when connecting to a headless Linux server?
A: When connecting to a headless Linux server, it'll cause your GPU to stop producing an image, which will result in a black screen as there is nothing for Splashtop to capture. Possible solutions are:
Make sure you're running Splashtop Streamer v188.8.131.52 or later (download link) and with LightDm or gdm3 installed as Display manager. Splashtop streamer will automatically detect it as a virtual display.
⚠️ Splashtop don't support Display manager that's not Lightdm / gdm3, please refer to this article on How to Change the Default Display Manager in Ubuntu 20.04 (The default display manager of Ubuntu16.04 is “LightDm”).
- Change it to the recommended resolution as other resolutions might result in display issues
a) Open the Business app
b) Click/tap on the edit icon next to the computer, normally a gear shaped icon
c) On the Resolution setting, choose "Native resolution of remote computer".
A: Although the system account might have the admin privilege, it's possible that it's not under the group admin, resulting in the login error.
For CentOS / RedHat / Fedora: Users should be under group “adm” or “wheel”
For Ubuntu: Users should be under group “adm” or “sudo”
You can verify the sudo privilege with the command $ sudo -v.
