To disable all bell sounds:
echo "blacklist pcspkr" > /etc/modprobe.d/nobeep.conf
echo "xset -b" >> /etc/xprofile
echo "set bell-style none" >> ~/.inputrc
In Debian, font rendering is not that great by default. It can be
customized using fontconfig
and xrdb
.
xrdb -query # check current config
mkdir -p ~/.config/fontconfig
cp fonts/fonts.conf ~/.config/fontconfig/fonts.conf
cp fonts/Xresources-fonts ~/.Xresources
