(I am currently using Ubuntu 14.04 LTS, GNOME environment)tl;dr How can I force more memory swapping (swappiness already at 100)?I have recently been experiencing a lot of system freezes/crashes. Often when accessing busy websites. It has been happening so much I have htop loaded on my tty, so I can switch to it and terminate my browser (as GUI does not respond). However, sometimes I need to use REISUB.I thought GNOME might work better than Unity, as my Debian system has no problems, and it did to a point, but I am still running high on memory, and getting freezes.I looked at my free -m today, and noticed my swap was showing 0 used. Output:             total       used       free     shared    buffers     cachedMem:          1821       1673        148        221         40        643-/+ buffers/cache:        989        832Swap:         1933          0       1933I did a temporary swappiness to 100 (sudo sysctl vm.swappiness=100). The results were still the same (0 being used even after running to near max system memory usage). I looked at this answer: How do I see if system is swapping?unfortunately as I am writing this, my system went into updates, and my packages are locked, so I cannot install this (sar) nor am I sure what package this is part of, in order to give another Output.I have looked in the fstab, and my swap partition is being used correctly. # swap was on /dev/sda3 during installation UUID=10fdfed2-1fde-4d9f-a8f1-3d2376b0ffcc none            swap    sw              0       0I am using a shared swap partition with my Debian OS (dual boot, separate partition, shared swap). But the partition is not locked, and I did a quick swapoff ..., swapon ..., and swapon -s to see if it would possibly recognize my swap and start swapping. It appears to still be at low swapping (84 hooray), but my memory usage is at 90%+ usage. With around 13% memory usage by Chromium, 17% by GNOME.I don't care if I am forced into slowness, but I can't be forced into full system freeze (can't access TTY, can't do Ctrl+Alt+Backspace, only Alt+SysReq R,E,I,S,U,B)I had the same issue with 12.04 LTS (pre-packaged), but have recently gone to 14.04 LTS. Bottom Line: How can I force swapping further, and/or control processes before they cause system stability issues? (Side Note: Debian works fine, except for mouse touchpad issue)Output of dmesg | grep error:[   26.646691] EXT4-fs (sda2): re-mounted. Opts: errors=remount-roThis is Ubuntu Partition.Same error on Debian Partition except sda7.
Swap appears to not be in use
memory;swap
