Is there any way to adjust the output volume of my speakers with the physical buttons on the keyboard without having to log in ?

If my screen is locked and an annoying song starts to play, I need to stop it quick fast and in a hurry. I'm not talking about doing this with soft controls via point and click. I want to do this with the actual physical (touchable) volume adjustment buttons on my machine. But it seems like I have to go through the tedious process of logging in before I can change the volume.

Any tips most appreciated. -chris

    What DE are you using ? – don_crissti Sep 12 '15 at 0:10
  • Generally this is not possible using the keyboard controls, because the screen locker is intended to lock the screen from all input. I recall seeing wishlist bugs filed against KDE and/or GNOME asking for this, but I think it's unlikely to happen. Perhaps someday, when we're all using Wayland, something like that could be implemented. As an alternative, you might consider using player software like MPD or Clementine, which can be controlled over the network, even with smartphone apps. They both work well for me. – blujay Sep 12 '15 at 0:31
  • One other possibility might be to use a gamepad. I don't know, but I suspect that you could configure a gamepad or other game input device to control the player software, and I suspect that could work when the screen is locked. You might need to have the gamepad software execute a script to control the player rather than sending the player keyboard input. – blujay Sep 12 '15 at 0:35
  • Hi.. thanks for confirming this is not possible, blujay. Do you want to make your comment an answer? I'll be happy to accept. It's not the answer I want.. .but it is cold hard reality it seems ;^) If anyone knows the URL of the bug for the wishlist item, please post.. I will certainly upvote it.. It seems like a really useful feature to have. anyway.. thanx again. – Chris Bedford Sep 12 '15 at 0:41

    @blujay - this is very possible at least in GNOME 3.6 and later (I'm not familiar with other DEs but I can't believe KDE doesn't also support this feature, it's usually more feature-rich than GNOME). When my screen is locked I can adjust the volume via Fn+F11 and Fn+F12 just like I do when I'm logged in (on my notebook those two keys are vol up and vol down when used with Fn) – don_crissti Sep 12 '15 at 1:12
