i have found a possible fix or workaround to the problem! i installed Ubuntu gnome 16.04 and to my surprise the ram usage was at 1.2gb idle and after just opening my browser and a youtube video it shot up to about 2.3gb which was alarming to say the least, so not one to give up i went in search for a solution and found nothing to help until a came across a very old post that had nothing to do with this particular problem but was taking about evolution services leaking ram, which at that point got me thinking ........ so i fired up the system monitor and proceeded to investigate which processes were consuming the most ram and to my surprise two processes in particular were at the top of the processes food chain 1- gnome-software 2-evolution and disable its processes, so i then proceeded to
uninstall gnome-software; > ( sudo apt remove gnome-software ) < then i removed evolution and its services > ( sudo apt remove evolution ) < disable processes -- type each command below in the terminal -- cd /usr/share/dbus-1/services sudo ln -snf /dev/null org.gnome.evolution.dataserver.AddressBook.service sudo ln -snf /dev/null org.gnome.evolution.dataserver.Calendar.service sudo ln -snf /dev/null org.gnome.evolution.dataserver.Sources.service sudo ln -snf /dev/null org.gnome.evolution.dataserver.UserPrompter.service and after doing this and rebooting my computer my ram was between 870MB and 950MB idle and about 1.2gb to 1.8gb with everything open eg browser youtube apps etc as many as i could open at the same time to test. also this workaround is assuming that you don't need to use evolution or gnome software but an alternative software center i use is Ubuntu mate welcome app and if i need any other particular piece of software i use command line or add a repo. hope this workaround can help someone until the problem is found and fixed. kind regards -- 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.
