** Description changed: After resuming from suspend, on average one in five times excessive swapping starts. This often continues for several minutes, but sometimes even for ten minutes or more (I'm not always patient enough to sit it out). During this phase, it is not possible to log into the screenlock, because the password dialog is not (yet) showing. I can log in to the text console, but repsonse is slow and sluggish. atop registers massive disk IO (duh) and equally massive memory allocation and de-allocation. Often, I see processes like firefox, thunderbird, Xorg, ooffice (and others) deallocating 100's of MBs, to reallocate them shortly after. WORKAROUND: Run the following in a terminal: gksudo gedit /etc/sysctl.conf - Change: - vm.swappiness=60 - - to: + Add to the end of the file: vm.swappiness=10 - Save and close, reboot your computer. + Save and close. Then reboot your computer, or execute: + echo 10 | sudo dd of=/proc/sys/vm/swappiness ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-32-generic 3.2.0-32.51 ProcVersionSignature: Ubuntu 3.2.0-32.51-generic 3.2.30 Uname: Linux 3.2.0-32-generic x86_64 NonfreeKernelModules: fglrx AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
