comment Preparing Ubuntu to be turned off unexpectedly?
This is for if they unplug it. If they're actually turning off a power switch, you can replace the power switch with one that just tells the computer to shutdown. I don't know how to do that, but it should be fairly easy.

comment Preparing Ubuntu to be turned off unexpectedly?
@Fabby - That gives me an idea. If you add a smart battery backup instead of a plain UPS, it can sense when power has been removed and send message to your system which can be used to initiate a normal shutdown. The battery will provide the power while the shutdown is being performed. I had an old APC which talked over a serial port. I'm sure all the new ones use USB.

comment Is it possible to put a GUI to more than just TTY7?
Although it's not exactly what you asked for, KDE has a feature called Activities. When you switch activities, you get a whole new set of desktops, possibly setup quite differently from your default. This sort of does the same thing as what you're asking for, but, AFAIK, does stay within one X session.

comment How can I see the amount of data I am Downloading / Uploading per day?
That's a really cool command I have not seen before! You could also get a much less accurate answer using ifconfig etho, but that will show everything sent and received - including control information, not just uploads and downloads. Also, if your router has a web interface like most do, it may display similar information on one of its status pages. Again, this is for everything, not just a particular type of data/traffic.

comment ln -s vs mount --bind
I haven't used mount --bind, but I doubt it can replicate the behavior of a symlink like ln -s ../../myfile .. If you move that to another directory, it will point somewhere else because it's a relative link. This can be useful if you need to backup a sub-tree and still have the links work in the backup.

comment Replace windows with ubuntu: What should I check in Ubuntu live
Along the same lines, if you have a backlit keyboard on a notebook, be sure to check that too. I finally go mine to work after almost 3 years. All I had to do was boot Windows (dual boot) and then turn the power off! This is way less than elegant, but is indicative of what can happen with special hardware.

comment Kde : How to minimize windows from the task bar
Don't know, but: What happens if you right click on an icon? Do you get a context menu with a Minimize option and does it work? (I'm using Kubuntu 14.04 and it already works the way you expect it to.) Do you have the taskbar set to show all windows or just the ones on the current desktop? I ask these primarily to get more info so someone may get a clue as to what's wrong with your setup. Also, what did you upgrade from - or was it a clean install?

comment Add column from one .csv to another .csv file
Thanks for the reply. I'm not sure what I want. I have to play with the actual data, but it would be things like subtotals per week of credits and debits. I also had some call center utilization data where I wanted to sum and average calls per minute. Nothing Fancy. I barely got a C in statistics for social sciences and I've forgotten most of that. I also would like to select columns without pre-filtering it in awk, etc.. I can code all of it in a programming language like awk, but for such a common task, there should be something that already knows how to do it.

+1 for showing me another tool for CSV data. Separate question, but do you know of a standalone report writer for CSV data files?

comment How to block specific apps from opening in specific accounts
I don't know enough to actually do it, but maybe you could setup all the critical applications to be accessible only by a group. Then, you could add advanced users to that group for full access. For the restricted users, you could use sudo (not to root) along with appropriate entries in sudoers to give them password protected access to the other commands on a case by case basis.

comment Printing footers using enscript
Thanks for the great information. It wasn't clear to me that your solution works without the patch. I use .enscriptrc. I didn't notice that .enscript is also available for the use you suggest. The enscript man page lists all those variables, but I didn't make the connection that you had to use them in custom header files.

comment Printing footers using enscript
+1 for finding a report that old! I guess enscript isn't used much any more or someone would have fixed something as basic as this. I'll study the report and your code a bit before accepting your answer. Unfortunately, my script is part of a project, so I won't be able to ask other users to implement a patch like this as well.

comment Headphone hiss after upgrade to 14.10
Do you get the hiss on the notebook speakers or just on the headphones? It won't solve anything, but installing alsamixer and running it from the command line will allow you to look at and change all your audio levels which may help to isolate where the noise is coming from.
