I must correct my comment#14, because with downgrading only the xorg-server-core package, the problem persists. You have to downgrade all xorg* relevant packages to a version before the security updates of the last weeks, as Francis Brown mentioned.
Furthermore I have tested the open-source driver nouevau. There is no memory leak, all is normal. But with this driver the KDE effects are very slow and window moving is terribly slow, etc. So I have to stick with the nvidia driver. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1402551 Title: High memory usage of Xorg and kwin after Xorg security updates [nvidia] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-304-updates/+bug/1402551/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
