Q When I delete a file in Dropbox, is it really gone forever, everywhere?
A No! Jens (FCM Mobile Edition) pointed out that if you log on to the Dropbox web interface, and open the folder where the file used to reside, you can click on an icon labelled “Show deleted files.” If you right-click on a deleted file, you get the option to restore it. I have yet to figure out how long it remains there.
Q When I open Home Folder from the Unity Launcher, the left side panel (Devices, Computer, Network) is missing. How do I get this to display again?
A (Thanks to DuckHook in the Ubuntu Forums) Press <F9> to toggle the sidebar.
Q What does “long term support” mean to the average user?
A (Thanks to cortman in the Ubuntu Forums) As far as Ubuntu/Canonical is concerned, it means they'll provide security updates and bug fixes for that version for an extended period. Beginning with 12.04, that period is five years for Ubuntu Desktop. Also note that beginning with 13.04, “standard” releases will be supported for nine months.
Q What is Mir?

Q I just tried hardinfo, and while it provides lots of information, it doesn't have the level of detail that I want.
A If you want a detailed description of your hardware, open Terminal and paste this command:
sudo lshw -html > Desktop/myconfig.htm
If you double-click on myconfig.htm, it should open in your browser, and give you a nicely formatted report about your hardware.
Q Is there a way to enable automatic login when I didn't select it at installation?
A If you click on the dash and type login, do you see “login window” as something you can run? If so, select the Security tab, and “Enable Automatic Login” is a checkbox item.
Or, it might be under “User Accounts”, where you click on “Unlock”, provide your password, then flip the “automatic logon” switch.
Q Is there an equivalent program to Sysprep for Windows? I want to set up systems which are ready to use, then when each end-user powers up the computer for the first time, he would be asked to provide a username, password, etc.
A (Thanks to Cheesemill in the Ubuntu Forums) When you boot the installation media, hit SHIFT to get to the installation menu, then hit F4 and select 'OEM Install'. When Ubuntu has finished booting, install the system as usual, you will be prompted for a temporary username and password.
When installation has finished, boot the system and log on with the temporary username and password you created earlier; you can now make any other alterations to the system that you want, for example getting updates and installing extra software. (Corporate wallpaper!) When you're all done, just double-click on the 'Prepare for shipping to end user' icon on the desktop and then shut down the machine. You can take an image of the drive, and install that on as many computers as you want.
Q I recently installed Xubuntu, but I like Nautilus better than Thunar, so I installed Nautilus. Now what?
A (Thanks to LewisTM in the Ubuntu Forums) Go to Settings → Preferred Applications → Utilities, and set the File Manager to Nautilus.
Q I received an email which caused Evolution version 3.2.3 to go into a CPU loop. I can't even delete it!
A You can fix the email. Set your file manager to show hidden folders, and navigate to .local/share/evolution/mail/local/cur
Each email message is a file. The time and date on the file will not match the email's time and date exactly, but it should get you close. Open the file in Gedit, and find the first thing which is not simple text. Delete from there to the end, restart Evolution, and you should be able to delete the message.
Q I have Ubuntu 12.04 installed on a Panasonic Toughbook CF-29 with a built-in GPS device. The GPS device does not show up in lshw.
A (Thanks to xraynetcontrol in the Ubuntu Forums) (Gord says: The GPS appears to be a serial device attached to what MS-DOS calls a COM port.) I needed to add myself to the “dialout” group. I did that by entering this into the terminal, and then rebooting the box:
sudo adduser (name) dialout
sudo dpkg-reconfigure gpsd
Since my laptop has an actual serial port on the back, I guessed that the GPS receiver was in serial slot 2, so I entered ttyS2, and kept everything else as a default.
So, enter:
stty -F /dev/ttyS2 ispeed 4800 && cat </dev/ttys2 xgps cgps
It took about 5 minutes to get a 2D lock on me, as I was inside. I closed out the terminals and launched a variety of GPS programs like GPSDrive, FoxTrot and Viking. All worked as expected.
Tips and Techniques You want to run a web server?
I frequently see questions from people who want to set up a website running on a home computer, typically stated as, “I set up a website on my computer, but it doesn't work. Please help.”
Instead of saying, “it doesn't work,” tell us exactly what you have done and what happens as a result. For example:
I have confirmed that my ISP allows customers to run a web server. (Many don't, so that's the end of it!)
I have purchased the static IP address 1.2.3.4 from my ISP. (It's possible to run a web site without a static IP address, but you're getting into “how to build a pocket watch in 394 easy steps” territory. Hint: dyndns.)
I have purchased the domain iamtank.com from the registrar Somereg, and have pointed it to 1.2.3.4 (probably the easiest step).
My server is set up with a static IP address on my LAN, and it is 192.168.1.32 (See last month's Q&A for setting up a static IP address on your LAN.)
I have set up my router to forward port 80 to 192.168.1.32 (The router's manual will tell you how.)
I am running Apache on my server, and other computers on the LAN get the web page when I enter 192.168.1.32 into a browser address bar.
Actually, if you have done all those things, it should work.
Be specific! Don't say mydomain.com, tell us your actual domain name, tell us your IP address.
