Hi, I couldn't find the shell variable that will give me the user who is currently logged on to display :0.0. My problem: I need to display a pop-up message every .5 hours on a computer no matter who is logged in. I have a script using zenity that will do the pop-up and if I log in as myself and automate this script with cron, the pop-up works fine, but only while I'm logged. If I try to add the same scipt to root's crontab then I get errors. This is the cron entry (set to run every minute for testing): * * * * * DISPLAY=:0.0 /path_to_my_script This is the error: X-Cron-Env: <SHELL=/bin/sh> X-Cron-Env: <HOME=/root> X-Cron-Env: <PATH=/usr/bin:/bin> X-Cron-Env: <LOGNAME=root> X-Cron-Env: <USER=root> Xlib: connection to ":0.0" refused by server Xlib: No protocol specified (zenity:7245): Gtk-WARNING **: cannot open display: So I need perhaps one of the following sollutions: -a way to give root access to :0.0 regardless of who is loggeg in? -a way to add an entry to all user's personal crontab -a way to determine (in my script) who is using display :0.0 and then run the script as that user. Any help is greatly appreciated. --Paul --- Oliver Leitner <shadow333@xxxxxxxxx> wrote: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: RIPEMD160 > > yes, theres a shell variable that you may just read > out, have a look > with "set". > > also theres who, finger, w > > and prolly others.... > > Paul Keyes wrote: > > | Is there a way to determine who is loggeg in > (maybe with 'who' > | command) and sitting at the terminal, so that I > can run the script > | as them? > | > | --Paul --- Oliver Leitner <shadow333@xxxxxxxxx> > wrote: > | > > | easy answer: > | > | try to run your script as non root user, eg try > sudo to run it. > | > | Greetings Oliver > | > | Paul Keyes wrote: > | > | | Thanks.
