Unfortunately, Samsung has recently announced the end of Linux on Dex support. The last time I mentioned LoD was when Samsung mentioned it was coming to more devices. A close associate recently acquired one of those devices to which support was coming. When I tried to get her sign up for the Beta I had found that there was no way to get her signed up. That was about two weeks before the Samsung announcement.
To summarize, Samsung stated what as one upgrades to Android 10 they would loose the Linux on DeX functionality; if someone wants to run a full Linux setup on their computer they will have to avoid upgrading. There was no statement on whether or not there will be anything to replace this functionality.
Personally I will miss this functionality. When I was finally able to access it I was able to leave my computer behind when I went on trips. While it wasn’t as fully ccapable as my laptop it supported enough functionality to be a secondary developerment solution; I could do enough things to respond to some unanticipated requests. I had access to GIT, Node, and various other development and command line tools include Visual Studio Code. Unless Google or Samsung plan to release a replacement this will be functionality lost with the next OS update.
In the mean time I’ll be looking back to the Chromebook. The Chromebook has some limited linux support that may be helpful. Though the last time I used it there was no where near as much functionality as LoD.
It will be missed. 😦
