comment Mint 17 Cinnamon: suddenly everything looks messed up
You changed nothing about the theme, but then you did change the theme. You've given us incomplete information as to what might have caused the problem. That's forgivable for a newbie. I'd reload the system from scratch and not touch any setting and see if that allows you play rogue (which was a bit too important to me in times past, too :)

comment Mint 17 Cinnamon: suddenly everything looks messed up
"I'm a complete newbie to linux." And with a day of experience, decided to change the visual theme. Don't do that; for reals. I've been using Ubuntu since April 2005 and other unixes for 20 years prior to that, I've never had a plug=in theme behave all 3 times I even bothered. True, I didn't give much effort, because they should need any. Switch back to default and learn about the system before you try to make it look coolz.

See if you can get a Hello world! PHP program to give you output under cron and let that guide you to a more precise question.

comment Weird vertical bar on my desktop
If I understood your exchange with @Anthon restarting the machine (or X) works for a time but it fails again later. That is very diagnostic of a display chip set damaged by overheating. It can easily cost as much to replace the chips as it would to get a new machine. Also, even if the chips were replaced there could be a design defect with the cooling system which can cause the GPU to fail again. Vacuum all the ventilation holes in the laptop and if that doesn't work, consider getting a new one. Sorry.

I second @DavidKohen hypothesis that it is a GPU hardware fault. Swap out the GPU to test the hypothesis.

comment What is my sudo password?
You, user derek, may not have sudo permissions; ask your sysadmin. In your comment you gave a weird error message "hello is not in the sudoers file" I thought our hypothetical user:password was derek:hello; I would expect an error "derek is not in the sudoers file" but sudoers never contains passwords.

comment Why doesn't Ctrl+R do anything in Ubuntu's terminal?
Weird. I'm going with the "demonic possession hypothesis". Be careful if your toaster starts acting up. ;)

comment Why doesn't Ctrl+R do anything in Ubuntu's terminal?
If possible, take gnome-terminal out of the path and try the GUI gvim. If ^R doesn't work there, then xev will show you the KeyPress and KeyRelease events. If xev doesn't show a keysym CONTROL and keysym r, contact an exorcist.

Your internet provider may be redirecting thepiratebay.se to localhost.

comment Avoid mutt sending mail with too many entries in To: or Cc: fields
Handling these test in the MUA may be was the OP was asking for, unfortunately, it's very easy to subvert. I can talk to sendmail directly. I can telnet to port 25 and talk to the MUA through a pipe. If I have a no telnet to the MTA but I have a compiler, I can easily write a program that talks to port 25. All this points to the MTA as being the proper place for filtering.

comment Automatically put an alias into ~/.bashrc or ~/.zshrc
@WillianPaixao not quite. The source command in this answer makes the alias immediately available, which your's does not. That's not an earth-shattering difference, but is is better than "logout and login again".

Do you know if eth2 has traffic on it? ifconfig -i can answer that.

comment Volume too quiet at maximum
I don't know the answer. I do know that manufacturers play pretty fast and loose with their printed specifications and speaker resistance, everything else being equal, should work in direct proportionality to current and voltage. But other things aren't equal and sound equipment manufacturers either a) like to hide these difference or b) don't know how to conveniently characterize these differences or c) like to play the marketing game of a bigger/smaller number is better/worse than another number.

comment How to make user passwords shown as a clear text in Linux?
It may sound like I'm making an argument for security through obscurity. I was trying to argue that it is unwise to give teenage boys whiskey and car-keys with instruction in neither. But I may well have failed in that attempt.

comment How to make user passwords shown as a clear text in Linux?
It is my sense that if one has to ask "Is there a way … to save the password in the /etc/passwd in clear text and such that the root can see them?", then they lack the relevant understanding as to why they oughtn't. Of course, the OP could always implement the holes you enumerate, but it seems unwise to aid someone in bad practice (even if he could find the information elsewhere). The OP will likely never be your sysadmin, and I'm sure you use unique strong passwords religiously, but many people are not so enlightened; I'm sure there are others who are not so rigorous.

comment Locale not being set on initial login on Raspbian/Debian
Please don't use pastebin when you could easily paste the text into the question directly. I fixed it for you. At least you didn't use screenshots as some new users like to do for simple text. ;)

comment Slow Linux machine
The OP doesn't say how long "too long" is, but as others above, I suspect that sshd is trying to inverse resolve the DNS name from the IP address of the ssh client and eventually times out because it fails. If this is what the problem is, none of your diagnostic commands will show anything because the resolver is just waiting for a timer to go off and is using almost no system resources (±0)
