@mieserwicht fabulous… thanks… i did NOT check if already set…

try it again, should not double it now and should say already disabled in the log file

@sdetweil
Get an error message now:

pi@magicmirror:~ $ bash -c "$(curl -sL  https://www.dropbox.com/s/ah7wtk30101xx4t/test_screensaver.sh?dl=0)"
grep: ungültiges Argument „pms“ für „--directories“
Gültige Argumente sind:
  - „read“
  - „recurse“
  - „skip“
Usage: grep [OPTION]... PATTERNS [FILE]...
„grep --help“ liefert weitere Informationen.

Edit: And it still adds the configs to the autostart file, even if they already exist

@mieserwicht yeh, had to escape the - on -dpms… try again

adding again, yes, it got an empty result due to the error
