I use gnome with auto login and it runs my vdr-sxfe.sh script as well.

Me too. In that case everything works fine, even if I kill the vdr-sxfe
process and the script restarts it.

In my case vdr-sxfe doesn't crash, but it freezes on startup a lot.
Restarting it generally helps.

How did you implement the wait? With a flag-file that is set in suspend
script and deleted after resume?

Good idea. I planned to kill both vdr-sxfe and vdr-sxfe.sh to use the
desktop. I could also swtich to another desktop and leave the frontend
running as is. Now we came to the real problem: when I kill the script, how
do I restart it so it will run in foreground.

Do you restart vdr-sxfe or the script? I need the script to be restarted and
run in foreground.
I didn't try using irexec yet, will try it later today. I hope it doesn't
run the commands in background since it will not work for vdr-sxfe.

Please send the script, I might learn something from it.
Thanks.

Agree.
