[Kernel-packages] [Bug 1572801] Re: Ubuntu 16.04 Unity desktop uses much more ram than Ubuntu 15.10
Definetly the newer kernels (non-officials) use a lot less ram memory than older one. But the problem comes with WiFi network card. In my case, I am not able to switch to kernel 4.8.6 because I loss WiFi conectivity (BCM4312 like any Dell laptop), I need to be stick to kernel 4.4.0 for now. -- 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.
