One of my favorite casual gaming setups is to use a slim laptop on my couch while streaming from my desktop using Steam Remote Play. The downside though is that unless I want to get up, Steam needs to be already running on my desktop. This post describes how I start steam remotely from my couch so that I can stream my games without having to get up and set it up on my desktop first.
|
|
|
|
This requires you to be already logged into a graphical session on the computer you want to stream from.
|
|
|
|
On Linux, there is a DISPLAY environmental variable which tells X11 where to show the application. By default (at least on Ubuntu), the display starts as `:0` and moves up in count. We can make use of this fact, to start steam on a X11 server instance that is already running so that we don't have to do any X11 forwarding.
|
|
|
|
On the client computer,
|
|
|
|
```bash
|
|
ssh desktop "DISPLAY=:0 nohup steam"
|
|
```
|
|
|
|
The `nohup` allows the application to not terminate when you press `CTRL-C` from your client computer.
|
|
|
|
Update: In light of [discovering `systemd-run`](/blog/launchappsthroughterminal/), I recommand you
|
|
do the following instead:
|
|
|
|
```bash
|
|
ssh desktop "DISPLAY=:0 systemd-run --user steam"
|
|
```
