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?

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.

Those are not set. So unfortunately no clue here :(. So far my only hope is to run older Ubuntu versions. – user19725 Apr 07 '10 at 06:29

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.

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.

ha I didn't read your last entry ;-) in Ubuntu 10.4 the pcspkr mod is blacklisted per default and in my case it's not even installed – grub Jun 14 '10 at 19:51

Thanks, I thought I had pcspkr disabled already, but probably wasn't. Also you pointed out pcsprk being blacklisted in the latest ubuntu. – user19725 Jun 16 '10 at 05:27
