comment Ubuntu sometimes starts swapping like crazy for no reason
I'm seeing this right now on precise. The consistent standout on iotop is compiz. Other standout is Chrome GPU process. Killing GPU process doesn't help. Background: I run lots of browser tabs (so frustrating how every web page demands app-level memory and cpu resources now!). But only rarely does compiz seem to thrash like this. Frustrating.

comment How to network two Ubuntu computers using ethernet (without a router)?
The answer using the "shared" method in NetworkManager at askubuntu.com/a/3117/6130 is much simpler, requires no configuration on one of the computers, and allows one of the computers to share an internet connection. It is the same as what @Robert Ancell is saying in his answer here.

comment How to add metadata to images using Shotwell
Thanks! But as the OP found, this Edit Title menu item is not visible when shotwell is run from the file manager or the command line (i.e. in some sort of "viewer" mode). Sad. See my bug report at bugs.launchpad.net/ubuntu/+source/shotwell/+bug/1393463

comment How to add metadata to images using Shotwell
Thanks for clarifying this! But this functionality should be provided in the viewer also. As described by the Library of Congress at blogs.loc.gov/digitalpreservation/2011/10/… it is an important, basic feature to see and add a description to a photo. At the least, the menu item should be grayed out, and this should be explained in the documentation. It is very confusing to have the documentation list an option which isn't there. See more at my bug report: bugs.launchpad.net/ubuntu/+source/shotwell/+bug/1393463

comment How do I remove or hide old kernel versions to clean up the boot menu?
I second the question from @spacediver - this is a crazy-slow process when you have 38 unneeded kernels, since as each one is uninstalled it goes thru all the remaining ones while generating a new grub.cfg. That is what we call an N^2 operation - it processes a kernel about (38^2 / 2) = 722 times, and is very slow. Surely Ubuntu can come up with something better....

This has changed to just System -> Startup Applications, in Precise 12.04 at least.

comment Is there a VRML2 (VRML97 / WRL) viewer?
As of Ubuntu Trusty 14.04, view3dscene is also packaged, as discussed at this (duplicate) question: (VRML) Files, How to Render - Ask Ubuntu. It has a much more intuitive interface than whitedune for simple viewing.

comment (VRML) Files, How to Render
view3dscene is packaged in the standard ubuntu archive for safe, convenient installation via your choice of package management tools as of Trusty 14.04 LTS. As noted in Is there a VRML2 (VRML97 / WRL) viewer? - Ask Ubuntu‌​, whitedune is an option in earlier versions of Ubuntu, back to lucid 11.10, but the interface in view3dscene is much more intuitive.

Odd. The /etc/default/keyboard approach works fine for me on Ubuntu trusty.

comment Are there any fax sending applications?
Do you have a fax modem and a phone line? E.g. a Class 1, Class 2, or class 2.0 fax modem? Or are you looking for something that would use VOIP (FOIP)? Or perhaps a web service like metrofax?

comment How to install Django 1.6?
sudo pip install is a bad practice, which may work for django but can really screw up someone's system in other situations. Don't undermine the advantages of having Ubuntu manage your packages. The clean way to do it is with virtualenvwrapper.

I agree with @AndersonGreen that the question of finding duplicate folders / directories needs an answer. See one option at Find all folders in a directory with the same content - Unix & Linux Stack Exchange

comment How to use Rhythmbox python console
Note that at least as of Ubuntu Trusty tahr 14.04, rhythmbox embeds python 3.4.0. So the command 'print "hello world"' is a syntax error ;) Instead, use the new Python 3 print function: 'print("hello world")'

comment Installing Java 7 Update 25 on 12.04 LTS?
PPAs can indeed be dangerous. But they can also be smart and more secure than a direct download, in the sense that they automate the process of upgrading. If the people running the ppa are trustworthy, and they sign their packages etc, then they are a good alternative to having people check the checksums of the tar.gz themselves, do the intstalls, and then constantly watch for notice of the need for a security update, and do it all over again. Note also that the ppa package does a number of other "update-alternatives" calls, for various installed programs that use java.

comment Can I control brightness on second monitor?
This is not in the normal repos, but is in the software center at least for 12.04. It does not change the backlight brighness, but does change the overall brightness, though I'm not sure how. It says it uses a proprietary license, but also says it is "gpl-3". Very odd. And I'd like a command-line interface that I can script to gradually lower brightness in the evening. But I'm still glad to have it - thanks!
