Ever tried to get rid of the annoying PC Speaker sound (e.g. when using auto-completion in a shell)? Under Ubuntu (and probably other distributions as well) do the following to bring silence to the masses:
For the running system:
rmmod pcspkr
Forever (aka after a reboot) edit /etc/modprobe.d/blacklist and add the following line to the bottom
blacklist pcspkr

Since upgrading to Ubuntu Hardy (what was I thinking when I did that…) I had the weird issue of my external screen (connected via VGA out) going black after a non-specific amount of time (e.g. sometimes after an hour, sometimes after 6 hours). xrandr still showed the external screen as connected and the monitor also received enough signal to actually not go into standby mode but whatever I tried, nothing made the black screen show my desktop again. So here is the workaround if you inhibit a similar type of issue (additionally the external screen lost sync for a tiny amount of time creating some kind of funny disturbed images from time to time - flickering if you will or maybe the matrix just tried fight it’s way to the surface):
Edit your xorg.conf to include the following Option in the Device Section of “Configured Video Device”:
Section "Device"
Identifier "Configured Video Device"
Option “FramebufferCompression” “off”
EndSection
Interesting: With the latest Ubuntu release the goal seems to be to actually have X guess all the configuration settings automagically so the xorg.conf was pretty empty after a fresh installation.
