colorado_chris Google Chrome's RDP app is perfect but it's a .deb package only.
I'm trying to get a Win 10 and RT (!) tablet used as external VNC displays and maybe even touchpads plus a Windows phone camera as a 'external webcam' OBS source in Solus and. A tough match. Didn't realize that the Chrome RDP needed a .deb install also before reading your post. I have shared desktop and windows in Hangouts before so that may be workaround?
Tried Teamviewer but was kicked out quickly ('this was a free session, bye') when connecting to a Win VM inside Solus and couldn't connect at all to the Linux app (that's probably a Win 10 Mobile app issue that they'll hardly fix now). The latency of the camera feed to the VM was surprisingly low but they're charging at least 27.90EUR/mo now so...
Someone on reddit suggested Steam in-home streaming (!) which actually almost worked out of the box here between tablet and a Kubuntu live boot, will give it another try in Solus. It's inside the LAN only though.
Staudey There are also Teamviewer and Anydesk in the 3rd party repository,
AnyDesk isn't in my software center but their appimage works fine, only remote mirroring though AFAICT.
