Still no luck with the latest nvidia driver 346.47! As soon as I use the driver nouveau, there is no problem, no high memory usage of kwin/xorg processes or graphics memory.
Furthermore I have tested a fresh installation with Kubuntu 14.04.2 Install-DVD with a complete wipe-out of all partitions of the SSD , but the problem occurs there too. -- 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/kde-workspace/+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
