Hi,

I use 5 different screen sessions for various different purposes on my
work computer (linux open suse). When the X server is restarted and I
re-attach the screen sessions I can no longer open programs that use
X. The error I get is "cannot open display :0.0" The xterm without the
screen session running can open an X app just fine.

Does anyone have any ways that I can stop this happening, usually it
isn't a problem but on the occsation it does happen I have to restart
the screen session.

Thanks
David

I use to script to save the x env:

#!/bin/bash
# Copy X env into a file that can be sourced from another shell.
host=$(hostname)
file=~/.ssh.env.$host
echo "set -a" >$file
env | grep -e SSH -e DISPLAY | grep -v TTY | sed -e 's/=\(.\+\)/="\1"/' >>$file
echo "set +a" >>$file

and an alias to reload it:
xenvload='. ~/.ssh.env.$hostname'

So form a new shell with the correct x env you run "xenvsave", then from the screen shells, run xenvload.

I'm sure there's an easier way but this works for me.
