##changelog Add Signal disconnect Fix coding error in v2 @mengzhuo Concerning Util.spawn: According to https://mail.gnome.org/archives/commits-list/2011-January/msg04210.html Util.spawn will handle errors on its own and report them via messagetray notification. This works just fine if I set the wrong command on purpose. from js.misc.util : // spawn: // @argv: an argv array // // Runs @argv in the background, handling any errors that occur // when trying to start the program. function spawn(argv) { try { trySpawn(argv); } catch (err) { _handleSpawnError(argv[0], err); } } If this is not what you meant, please let me know

For issue 2: I mean what if your program is not existed on some Linux distributions? Surly the worst case is that your extension crashed and user have no idea what is going on. >> Util.spawn will handle errors on its own and report them via messagetray notification. This works just fine if I set the wrong command on purpose. I can't confirm that on ALL gnome-shell versions, but it's OK for your code to go, so I gonna approve it.

This is what I get for messing with the code, stupid me: My purposely changed command 'xfrset' ended up in the extension.
