Greetings, it's been a looong, long time since the last time I did this, so I need a bit of help to refresh my memory. In a sense, what I'm unable to remember right now is what docs I should read... I have a cron shell script that, if some event happens, must: 1) check if a *local* user A is currently logged in, and in which session/display 2) if yes, pop up a window in the session of user A, showing the content of a text file I know how to do (1) with "who": [marco@polaris ~]$ who bill :2 2013-09-10 19:56 this tells me that "bill" (i.e. NOT me, another user!!!) **is** currently logged in on display :0 and I also know how to do (2) with kdialog, zenity, xmessage... but of course, if I launch kdialog I get nothing but the "Error: can't open display" message. Setting DISPLAY to ":2", "ip.address:2", ":2.0"... doesn't change anything. (many) years ago this was solved with xhost +, but not now. So, what is the current way to make (2) happen? Possibly one that is distribution-agnostic?
