Disable visual system beep on Karmic

Question

Some programs are about to make me epileptic with excessive screen flashing/blinking (terminator etc.). In Ubuntu Hardy Heron I could solve the problem by unchecking System->Preferences->Sound->System Beep->Visual system beep. However on Karmic Koala there is no such option. I googled and found many solutions for turning off visual beep/bell. However nothing seems to work. So my question is that what is the exact alternative to disable Visual system beep on Karmic?

Answer 1

Maybe the problem is the module pcspkr

check if the module is loaded

 lsmod | grep pcspkr

if its loaded you can unload it with

 sudo rmmod pcspkr

if the annoying beeps disappear you have to blacklist the module: Add the line

 blacklist pcspkr

to the file /etc/modprobe.d/blacklist.conf if it exists. I do not know how ubuntu 9.04 or 9.10 do store the blacklisted modules.

Answer 2

Try running:

gconf-editor &

and navigate to:

/apps/compiz/plugins/fade/screen0/options/visual_bell
/apps/compiz/plugins/fade/screen0/options/fullscreen_visual_bell
/apps/metacity/general/visual_bell_type
/apps/metacity/general/visual_bell

and see how they're set.

Also, some apps (e.g. screen) have their own controls for the visual bell.

Answer 3

It might be that my question was obsolete. I could repeat the problem with 9.04 and 9.10. With 8.04 and 10.04 there is no problem.
