![[solved] raspberry pi: A window manager is already running on screen](https://techblog.willshouse.com/wp-content/uploads/2013/06/solved-raspberry-pi-a-window-manager-is-already-running-on-screen.png)
A while ago I did a post about [using remote desktop with raspberry pi](https://techblog.willshouse.com/2012/07/18/remote-desktop-to-raspberry-pi-from-os-x/) – that was a fun, successful project. Now it’s been a while since I had to do the setup on a new raspberry pi machine and when I tried to remote desktop to my new pi I got this error:
> A window manager is already running on screen
Well that’s no good!
The problem turned out to be fairy easy to resolve:
I was `ssh`ing into the `pi` as the root user `ssh [email protected] -X` but I should have been connecting as the `pi` user (`ssh [email protected] -X`) – once I got that straightened out and ssh’ed in and ran `lxsession` the GUI / remote desktop for pi fired right up!
