Q What is the easiest way to get rid of old kernels?

A (Thanks to Bashing-om and morgaes in the Ubuntu Forums) Run these commands:

sudo apt-get update

sudo apt-get dist-upgrade

Reboot.

One more command:

sudo apt-get autoremove

It's a new use for “autoremove.”

Q I went and bought this WNDA3100v2 N600 Wi-Fi adapter; now I need help setting it up.

A If you can follow these instructions, you should be OK: https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper

Generally, it's a good idea to Google “[device name] linux” before buying hardware. Many USB Wi-Fi adapters work as soon as you plug them in and reboot, but printers, webcams, and Wi-Fi adapters, have varying levels of support.

Q I use VLC media player to watch TED Talk videos, but I would like to download them instead.

A (Thanks to mc4man in the Ubuntu Forums) The TED site supports downloading, but it's not obvious. When you select a video in your browser, there is a “download” button. That starts the video playing, but you can pause it, then right-click in the video and select “save video as”.

Q I added a ppa and installed simplescreenrecorder. How can I completely remove it?

A (Thanks to deadflowr in the Ubuntu Forums) Simplescreenrecorder installs two packages, so use these commands:

sudo apt-get purge simplescreenrecorder*

sudo add-apt-repository –remove ppa:maarten-baert/simplescreenrecorder

sudo apt-get update

Q How do you delete Windows software installed in 14.04 using the program's native installer (not through WINE)?

A The uninstaller is also a Windows program, so you may be able to uninstall using an uninstall program UNDER WINE.

Many applications do not include an uninstall program, so all you can do is delete the files.

The general approach is this: in your file manager, set it to display “hidden” files and folders. In your home folder you will find a folder called .wine, and under it is drive_c, which corresponds to a C: drive in Windows. It contains Program Files, among other things.

My own approach is to leave things alone until I do a re-install of a new version, such as Ubuntu 16.04 LTS. Deleting a single movie saves more space than dozens of programs.

Q Today, Xubuntu 14.04 software update installed the same kernel 3.13.0.46 for the third time. Why?

A It was actually 3.13.0-46.75, and there was a regression requiring the updates.

Q Is there any way to synchronize Evolution Mail and my Hotmail account?

A (Thanks to sandyd in the Ubuntu Forums) See this web page for IMAP and SMTP settings that can be added to evolution: http://windows.microsoft.com/en-us/windows/outlook/send-receive-from-app#

Q My system sometimes locks up. I would like to know the exact time my system locks.

A Run conky, and include the time in the conky display.

Q In a text file, once the line containing “Heading” is found, how can I display the next 20 lines?

A (Thanks to Lars Noodén in the Ubuntu Forums) Grep can do this:

grep -A 20 Heading /path/to/somewhere/somefile.txt
