I would like to set up my terminal to use a visible bell notification. Konsole is my preferred terminal emulator, but I can't seem to figure this out.

Everything I can find on the web points me towards set bell-style visible in .bashrc, or towards Settings->Configure Notifications. The bash setting seems to have no effect, and under configure notifications, none of the options corresponds to a visible bell. konsole notification settings

P.S. for extra credit, if anyone knows why konsole started ignoring the characters "s" and "v" from either keyboard or clipboard when I tried the following in bashrc, I can add that as a separate question: bind bell-style visible

  • By "visible bell notification" do you mean a popup notification? I have that in place for "Bell in non-visible session". It should work the same for "Bell in visible session".

  • I'd prefer something a little less intrusive, like a brief colour inversion. I really don't want to have to take any action to stop the bell.

  • Hmm. You might get some clues at faqs.org/docs/Linux-mini/Visual-Bell.html#s6 . I'm not aware of anything specific to Konsole.

    @JoeP That's not relevant. Konsole ignores the terminal's visual bell setting that can be set by applications, it always performs the action(s) configured in its preferences, and these don't include a traditional visual bell.

    For the extra credit: it's bind 'set bell-style visible'. Bash does strange things when a readline command is malformed instead of showing a proper error message.

Thanks to @Gilles' hints, I put together something that flashes the command window when there is a bell in a visible session. To do this I wrote a quick bash script:

#!/bin/bash
#flash console as a visible bell
#requires installation of xcalib

xcalib -i -a
sleep 0.01
xcalib -i -a

and entered the full path to this script under "Run command" for "Bell in Visible Session" in the konsole "Configure Notifications" dialog.

I'm not sure if it was the case back when this question was asked, but the main bell settings are separate from those notifications settings.

Open Settings > Configure Konsole > Profiles, select a profile (you may need to create a new one if you have only the read-only default), then click Edit. On the General tab of the subsequent dialogue, there is a setting at the bottom called Terminal bell mode, and there is a Visual Bell option which inverts the colours.
