I don't know how to make all that things right, but I've applied Aaron Plattner patch to Michael Vogt compiz 0.7.6 and solve this problem.
I'll now try to add self-made package to my PPA, may be anyone can help me to do it ? ** Attachment added: "Patch for source package compiz 0.7.6 hardy from https://launchpad.net/~compiz/+archive/ppa" http://launchpadlibrarian.net/22831227/compiz-bugfix-149764.patch -- [nvidia] slow gtk popup menus with gtk dual head https://bugs.launchpad.net/bugs/149764 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
