theapache64's questions

I turned on the recorder, and said "Hello..Hellloo...Hello", and the output is this. I tried various sound recorders, and the output is same. I am using Ubuntu 16.04.

How do I fix this issue ?

I've been upgrading my ubuntu 14.04 to 16.04 through this guide.

This is what i did,

First, I did sudo apt-get update and it updated successfully.

Then, I did sudo apt-get upgrade and it downloaded packages around 300MB or something.

After than, I did sudo apt-get dist-upgrade which downloaded about 800MB of data.

Then the system restarted. Now it's not booting up. As of now, It just shows a blank screen and my CAPS-LOCK INDICATOR is blinking infinitely.

How can i solve this problem ? Please help. If you need more clarification, ask me in the comments.

Edit:

Now I've ENABLED Secure Boot from BIOS, and now am getting some errors on the screen.

Simply, the GUI windows are breaking down.

As you can see in the above image, the text in the launched windows is unreadable.There's also some black shade around the corners of the active window. I don't know why this occurs, and most of the time it happens to every window (Not only for the window in the screenshot).

Here's my system configuration

Memory : 2.9 GiB
Processor : Pentium(R) Dual-Core CPU E5200 @ 2.50GHz × 2 
Graphics : Intel® G33 x86/MMX/SSE2
OS Type: 32-bit
Disk : 75.5 GB

Linux John 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:18:00 UTC 2015 i686 i686 i686 GNU/Linux

So here are my questions:

1) Is this happening,because of the low system configuration? If yes, which would be the most suitable linux distribution for the above configuration ? (I just want to run Android Studio in the OS).

2) If it's not a system configuration problem, How can I fix this?

If you have any questions, ask me in the comments please.

I am trying to install Dbeaver 3.5.6 on Ubuntu 14.04, but it shows some Java run-time missing error even though I've Java7 installed on my system.

Here's how I tried to install

1. user@Demo:~/Downloads$ wget http://dbeaver.jkiss.org/files/3.5.6/dbeaver-ce_3.5.6_i386.deb

2. user@Demo:~/Downloads$ sudo dpkg -i dbeaver-ce_3.5.6_i386.deb

and it throws an error like this

(Reading database ... 170900 files and directories currently installed.)

I am sure that the java installed on my system.

user@Demo:~/Downloads$ java -version

I think DBeaver need openjdk instead of normal oracle_jdk, isn't ?

How can I fix this problem ?

1. Should I install openjdk too ?
2. Can openjdk and normal oracle jdk work simultaneously in one system ?
3. Is there any alternative tool for DBeaver in Ubuntu. (I mean, which is the best one? ) ?

PS: am new in Ubuntu.

I was a Windows user and am new in Linux environment. I just installed Ubuntu two days ago and I am confused about the directories such as lib, etc, var, tmp, mnt, etc. I've few questions.

1. What is the purpose of these directories?

Currently I keep my project files in /home/shifar/Public/Projects, but that sounds too long...

2. Is there any way to shorten the file path?

3. Is it good to keep my project files in the above mentioned directory? Or is there any convention? Like Personal files must be stored there. and Software is better stored in there..
