** Description changed:
- As per instructions from Christopher M. Penalver (penalvch) on #391628,
- I'm filing this report.
-
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.
- System details in attached info, I'm sure (as per 'ubuntu-but linux' as
- instructed).
+ WORKAROUND: Run the following in a terminal:
+ gksudo gedit /etc/sysctl.conf
- I'd be very interested in fixes, workarounds, or any tricks that can
- alleviate the symptoms.
+ Change:
+ vm.swappiness=60
+
+ to:
+ vm.swappiness=10
+
+ Save and close, reboot your computer.
