Hello everyone,
i've looked almost everywhere for a solution but all posts/discussions i found were about get completely rid of it... not what i want!
I'd really like to reduce it to about 8-10s that are more than enough for a not-braindamaged person to change his mind and click some other option...
Seems there is no option to change it (quite surprised about this) so i'm asking if what i want can be achieved manipulating some config file.
Another reason for my request is that i've wrists problems so every click on the mouse/keayboard button press i can avoid is pure bless.

Thanks to everyone and sorry for my bad english

I'm not sure if it is currently possible to change the default 30 seconds logout, you can de-select boxes in Settings > Startup & Shutdown > Desktop Session and leave the boxes blank but this will shut your PC down immediately and not offer you any chance to change your mind?:

I hope it helps.
