Oh absolutely. You're a capable and confident hacker. But the fun thing about this community is that it contains people like you, who know exactly what you're doing, and people like me who never heard of 'x-term' before they landed here.

I think the trick with responding to a basic question like this one "Can I turn off the vibration on alarms?" is to offer an answer at both levels, and let the user decide which is suitable for him/her.

Basic answer: no, I can either have alarms on or off (though if people would be so good as to provide feedback on tweakr, I believe there [will be] an app for that).

Advanced answer: yes, by using this command line in x-term.

The user can choose.
