With the new Ubuntu 11.04, the scrollbars in almost all applications and windows look radically different than those we grew accustomed with. Here’s how to revert them to the old looks:
sudo apt-get remove overlay-scrollbar
echo "export LIBOVERLAY_SCROLLBAR=0" > /etc/X11/Xsession.d/80overlayscrollbars
This simple tutorial will explain how to disable or change the Alt+left mouse from moving windows in Ubuntu 12.04 gnome-shell and unity desktop.
There used to be a built-in utility for switching this movement key to an other in Gnome 2.
I don’t know why ‘Move Window’ plugin in CCSM doesn’t work in Ubuntu 12.04.
