I have a laptop in a cloned setup with an attached external monitor. Screen goes black for a second on the external monitor whenever opening a new program. I have an Intel 945GM video card.

For some reason, it does DDC detection every time a new application is open (so every time a new app connects to the X server).The following lines are printed in the /var/log/Xorg.0.log EVERY TIME an application is launched:

imi@orcl:~$ tail /var/log/Xorg.0.log -n 30

This seems dup with bug#16224. It's not driver bug, but GTK issue.
