I see a lot of chatter that is likely confusion related to the leak manifestations, and the false belief that eliminating X or Y memory consumer "fixed" the problem. The proper test is probably to leave a computer running, idle for 24-48 hours; if you begin swapping and running out of RAM while taking no action, you are still afflicted. Anyone who has not done that will not know if the issue is fixed.
As this leads to swap thrashing for anyone who leaves their computer running (which is many people), this software bug is leading to real- dollar hardware damage (as write spam kills flash memory drives). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1572801 Title: Ubuntu 16.04 Unity desktop uses much more ram than Ubuntu 15.10 Status in linux package in Ubuntu: Incomplete Status in linux source package in Xenial: Confirmed Bug description: Ubuntu 16.04 64bit ISO number 20160420.1 unity version 7.4.0+16.04.20160415-0ubuntu1 Ubuntu 16.04 64bit ram usage has increase dramatically over Ubuntu 15.10 Ubuntu 16.04 ram roughly 1 GB Ubuntu15.10 can be tuned to 420, 450 MB Ubuntu 16.04 with unity uses 1GB whereas Kubuntu 16.04 is using 420MB live usb ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: unity 7.4.0+16.04.20160415-0ubuntu1 ProcVersionSignature: Ubuntu 4.4.0-21.37-generic 4.4.6 Uname: Linux 4.4.0-21-generic x86_64 .tmp.unity_support_test.0: ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 CasperVersion: 1.376 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Thu Apr 21 01:44:22 2016 DistUpgraded: Fresh install DistroCodename: xenial DistroVariant: ubuntu GraphicsCard: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06) (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc.
