I am getting permission denied too. I'm not running it in root because of the first step in the instructions. I also have not restarted my N810 since I tried this nor have I tried launching gv-notifier yet. I also was not able to edit the conf.xml, although I didn'tg gainroot to do that so I wsas wonderfing if that was tghe issue. That's also why I havedn't tried launching gv-notifier, since I was unable to edit conf.
