Mina Michael's questions

Following this guide to install mongodb but mongo just doesn't want to start.

When running sudo systemctl status mongodb It just shows Active: failed (Result: exit-code). There's no useful output in this. How do I find out why is it not starting?

Edit:

output of ls -al /etc/systemd/system/mongodb.service

Hp x360 Laptops have a "hinge screen". The screen can be opened and flipped till 360 degrees.

I want to do some scripting with some commands that activate when the screen is flipped beyond a certain angle. How can I detect the angle?

...I'm imagining it's a function that returns some value (within a range of values)? Does it work that way? Or maybe is's a "flag" set to true or false?

How can I check?

Will the applications I install through ubuntu-make update themselves automatically? Like when I install something with apt-get or like when I add a repository.

I want to know what version of gstreamer I have installed.

If it turns out that I have multiple versions I want to know which is being used.

Edit:

It turns out that things are a bit messy. There are multiple versions of gstreamer (mainly 0.1 and 1.0) and they're being used in parallel (they should be treated as separate) (Source). As for the packages there's plenty of them. Here are the packages that came out from the dpkg -l | grep gstreamer command:

Are there any Realtek audio drivers for Ubuntu? If yes where do I get them and how do I install them correctly? (for Ubuntu 14.04 64bit) Also with jack work okay after I install them?

Curious about the reason? The ALSA drivers don't support microphones for my soundcard (Creative Sound Blaster 5.1 VX). Also, It does not handle audio output quite well. I have issues. Also, I'd really like some software like the windows-only "Realtek Audio Manager" that does effects to the audio such as echoes and so on.

Cheese just doesn't detect the webcam .. nor other software. This is an MSI GT70 2PC. I cannot even find someone having the problem. The webcam even works fine on windows 8.1 .

I also tried adding the user to the video group and I even tried this:

sudo chmod 777 /dev/video*

following this question but ubuntu can't find the directory in the first place!

I'm having trouble getting sound out of Ubuntu. Some article advised to enable the "speech dispatcher" from /etc/default/speech-dispatcher. What is it? What does it do? Any ideas?

Sometimes my network manager indicator (applet) shows as if I'm not connected to wifi (no bars) and when I right click it it says "networking disabled" although I am connected to the internet. Maybe it's a bug or something.

Running sudo service network-manager restart fixes this applet. It restarts the whole network. Does anyone know a simple way to restart just the applet? (nm-applet)

The xfce "indicator plugin" keeps crashing with almost all apps. However I need it. I just want it to keep trying to restart itself automatically (preferably every 10 seconds) instead of displaying this annoying message Plugin "Indicator Plugin" unexpectedly left the panel, do you want to restart it? Does anyone have an idea about how to do this?

I followed normal steps to assign Alt+Ctrl+T to open a terminal window. (Menu → Settings Manager → Keyboard → Application Shortcuts → Add and follow steps) but it just doesn't seem to work. I was following this: How to open terminal on Xubuntu and some other sources.

Why isn't it working? How do I make it work?

After I installed "kubuntu-desktop" my loading screen was changed:

to this:

How do I change it back?

I'm new to compilation. I'm installing FFmpeg and there's a make distclean (or once there was make clean) after every step. What does it do?

I right-clicked the title bar of Rhythmbox and then clicked Un/Decorate. Now the title bar is gone. I want it back and I can't figure out how.

I tried hitting D, but nothing happens.

I want to install Ubuntu Studio and I'm aware that it uses a different Linux kernel than normal Ubuntu. Is it possible to install both kernels and chose which one to use on every startup? And if yes, how do I do that?

I'm not very experienced. Also tell me if there are other more differences between Ubuntu and Ubuntu Studio other than the Linux kernel and the preinstalled software they have. Thanks in advance :)

The "File browser panel" plugin says "Easy file access from the side panel". What side panel? The launcher maybe?

I was watching 4 Tricks to Speed Up Ubuntu - YouTube and it said to turn off this plugin. I just want to understand what I'm dealing with.

I was reading about swappiness in various forums and I saw some videos. Many stated that it's a good thing for desktop users to decrease the swappiness value below 60 (which is the default). Some stated that 60 is good for servers. Exactly why would it be better for me to lower it and why is 60 good for servers? I tried to search for an answer (I looked here for example) but couldn't understand. ...Please use easy terms :D

I used badblocks to scan a partition on my hdd for bad sectors and it gave me the following output

...from what I understand it looks like "one scratch on the hdd" ... anyways I can't partition with gparted because of this bad sector (my previous question: I need help with increasing the size of the file-system partition. Partitioning-o-phobia!) gparted still gives me "a red exclamation mark" on the drive after the badblocks test. ...now what?

I have also tried chkdsk on windows but still gparted gives the red mark

How do I mark this bad sector so that gparted can do its work? :) ...plz exclude answers about "replacing the hdd" I know I can do that.

I'm trying to download winamp's website in case they shut it down. I need to download literally everything.

I tried once with wget and I managed to download the website itself, but when I try to download any file from it it gives a file without an extension or name. How can I fix that?

Sometimes, when installing things its says "dependencies" are missing.

What are dependencies?

It's NTFS. It's USB2. I'm using Ubuntu 13.04. It works perfectly fine on Windows (which excludes cable and hardware problems). I have two Ubuntu computers and it's not detected on either. It's about 500 GB.

Bottomline: video explaining the solution

Edits:

Following the first link, I input sudo lsusb in a terminal; before and after connecting the HDD. The difference was Bus 001 Device 012: ID 14cd:6116 Super Top M6116 SATA Bridge. There it is! ("sata bridge" used to appear in a windows notification when I plugged in the HDD in!). ...This means that Ubuntu detects it but is it not mounting it?

I tried this:

sudo mount /dev/sdb1 /mnt

But gives this:

mount: special device /dev/sdb1 does not exist

I also tried:

sudo mount /dev/sdc1 /mnt

but it stays with no output forever. I left it in background for about 30 min.s.

sudo fdisk -l gives out this:

Partition table entries are not in disk order

The part below "Partition table entries are not in disk order" takes about 5 minutes to appear.

The outputs of ls /dev/ | grep sd before and after connecting the HDD:

before:

sda
sda1
sda2
sda3
sda4
sda5
sda6

,after:

sda
sda1
sda2
sda3
sda4
sda5
sda6
sdd
sdd1

The second output has the lines sdd and sdd1 different from the first one.

IT SHOWED THE FILES!!

The command sudo mount /dev/sdd1 /mnt worked after I typed in sudo fdisk -l!!! Thanks a million!! :) :)
