After downgrading the package xserver-xorg-core to version 1.11.4-0-ubuntu10.14, the problem is gone.
It is definitely a issue with the security updates (1.11.4-0-ubuntu10.15 and 1.11.4-0-ubuntu10.16 and trusty xstack versions 1.15.1-0ubuntu2~precise3 and 1.15.1-0ubuntu2~precise4). It seems this memory leak is only with the nvidia binary driver (and kde?). Has anyone tested this fglrx? With the open source drivers radeon and intel there is no problem. Nouveau? I will test Unity for the occurrence of the memory leak and I will post the results. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
