I am using a Raspberry Pi 2 running raspbian.This little guy is going to basically be a media server.I would like to be able to push messages when I ssh into the thing, but when I try to echo message |write, it doesn't show up on startx.Is there away to create a popup that will flash in the corner on the television when its being used?
pushing messages as root to user using startx
command line;raspberry pi
Plenty of ways. Like this simple one:echo message | DISPLAY=:0.0 xmessage -geometry -0+0 -timeout 5 -file -Any solution requires you have access to the X server, though.  So perhaps switch to the user owning the display first?
