Again, you have to manually reinstall the ppa version, because 1:0.9.7.8-0ubuntu1.2 is a newer version than 1:0.9.7.8-0ubuntu1vvpreproposed2. Or better said, you have to downgrade the packages by forcing them to the version you want. This is done the way mfwhite5 said (right after my first comment), or here it is with apt-get (very similar):
sudo apt-get install compiz=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz- core=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz- gnome=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz- plugins=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz- plugins=1:0.9.7.8-0ubuntu1vvpreproposed2 compiz-plugins- default=1:0.9.7.8-0ubuntu1vvpreproposed2 libdecoration0=1:0.9.7.8-0ubuntu1vvpreproposed2 Or you can try: sudo aptitude which has a nice ncurses interface, where you can browse the packages and the different package versions. (I don't go into more details, because I don't think this is the place for a debian package management tutorial; this bug report is already way too long) But make sure you have added vanvugt's ppa, because apt-cache show compiz | grep Version: | awk '{ print $2 }' should say: 1:0.9.7.8-0ubuntu1.2 1:0.9.7.8-0ubuntu1vvpreproposed2 1:0.9.7.6-0ubuntu1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/862430 Title: window flicker for a short time after switching workspaces To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/862430/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
