If the application works well please create a new issue with the app id and grid image so it can be added to the set of installable default apps. The Flathub app id can be obtained from the last part of the URL of the Flathub page for the application. Just add a PNG or JPEG image of size 460x215 or 920x430 with the Flathub app id as the file name under that directory. The set of available applications will be expanded over time.Ĭhimera also looks in ~/.local/share/chimera/banners/flathub/ for a list of additionally allowed Flathub applications. Many applications on Flathub have compatibility issues with the ChimeraOS compositor and require testing. Only a limited set of applications are available for immediate installation from Flathub.

You can connect to Chimera on ChimeraOS by opening a browser on another computer and entering chimeraos.local.
