This thread is created for solutions to all problems related to Ubuntu.
I'm tagging the people who would help #-Link-Snipped-# and #-Link-Snipped-#

First problem I'm facing :

I downloaded adobe flash player, it's downloaded and it's showing a status installed in Ubuntu Software Center, but when my brother wants to run a small online game, it doesn't start saying no flash player found.

Help me in rectifying this.

Between

cd /usr/lib/adobe-flashplugin

and
ls

we have to give space or press enter after first code and then enter second?

Open Terminal & type :

cd(space)/usr/lib/adobe-flashplugin(Press Enter)

Now you are in desired directory :
Now type "ls" then press enter.

For Information : cd = change directory, ls = list directory (shows up all the files present in the directory)

Simpler still, give output of:
```
ls /usr/lib/adobe-flashplugin
```

Alright Screw these!
You might endup banging your head on wall.

Open terminal & type :
```
 sudo apt-get remove flashplugin-installer 
```
This will remove flashplayer.

Now restart the PC, Open Terminal again & type :
```
 sudo apt-get install ubuntu-restricted-extras 
```
This will install audio/video codecs + Flashplayer.

Well still it doesn't work then, open this link : #-Link-Snipped-# & Download the Google Chrome .deb file
(For Information : Like in windows there is .exe executable file for software installation, Ubuntu uses .deb packages)

Now you have to learn how-to install .deb files in Ubuntu:

Method 1 : Lightspeed Method Using Terminal

By default .deb file will be downloaded to "Downloads" Folder in Home directory.so we need to cd to Downloads.

Open Terminal & Type :
```
 cd Downloads 
```
Press <Enter> & then type :
```
 sudo dpkg -i <Name_Of_File.deb> 
```
Press <Enter>

It will be installed.

Method 2 : GUI

We need a software named Gdebi for that.
Open Terminal & Type :
```
 sudo apt-get install gdebi 
```
Press <Enter>. Software will be installed.

Now in Downloads folder, the downloaded google chrome .deb file is there.
Right click on it & Open with Gdebi installer.
It will ask for password, type in password & it will get installed.

Ok, problem is, whenever I switch on my system, it shows, that, my graphics settings are not detected properly, and I've to configure it manually, I press enter and taken to another screen, where there are various options, but nothing works (I can't choose anything, because my keyboard and mouse doesn't work on that screen..)

Then I've to start the system various times.. to get it properly booted..

My graphics card is Nvidia geforce gt 610m optimus...

#-Link-Snipped-# told me to open terminal and execute this command..
```
sudo apt-get install mesa-utils
```
And now it's done, what's next..?

Tell me the driver's version of your Nvidia chipset.

Try this : dpkg -l | grep -i nvidia

After executing the command in terminal, it's showing this

ii  nvidia-common                                1:0.2.44.2                                      Find obsolete NVIDIA drivers

Abhishek Rawal

@abhishek-fg9tRh • Aug 10, 2013

Sanyam KhuranaDriver : Intel® Ivybridge Mobile x86/MMX/SSE2
Which means you're using Intel's Opensource drivers & not nvidia's.
Problem is not with the nvidia graphics drivers.

Install Bumblebee.

Abhishek Rawal

@abhishek-fg9tRh • Aug 10, 2013

But before that do the following :

sudo apt-get remove --purge nvidia-*
sudo apt-get install ubuntu-desktop
sudo rm /etc/X11/xorg.conf
echo 'nouveau' | sudo tee -a /etc/modules

Reboot the system.

Nouveau is Opensource Nvidia drivers.

Also tell me, how to install winzip, I want that for Wine..

Abhishek Rawal

@abhishek-fg9tRh • Aug 10, 2013

Winzip or winrar ?

You don't need winzip as 'archive manager' is already there.
For winrar download winrar.exe from somewhere & install it with wine directly. It will work.

Right click on .exe file, install it like you do in Windows & then run.
Most small softwares don't need any other configuration, they work out of box.

It's installed, but I don't know how to run it..

I browsed the file, and found NiPie.exe but when I try to tun it, nothing happens..

Go to /Home & type Ctrl+H (It will show hidden files)
You will see .wine folder, there will be C drive like you see in Windows, browse it & open with Right click-> wine loader

BDW, how much swap area should I allocate? or if I just don't allocate anything.?

0
Abhishek Rawal

@abhishek-fg9tRh • Aug 11, 2013

Swap Area = 2x RAM size.
But I have noticed that SWAP Area will never be used by Linux. Swap Area works like virtual Ram when system consumes all the physical memory it will use swap area so the system doesn't hang.

Yup I read that, so I'm gonna allocate around 8 GB 😉

You'll never need that many of. Swap Area used to be very useful during old times when 256 MB RAM were treated like 16 GB RAM.
Now a days, it's wastage of memory. 16 GB is just insane amount for SWAP Area.

I have 4 GB of RAM, and I think it's enough, but still if I want to allocate some SWAP memory, how much should I allocate ?

Abhishek Rawal

@abhishek-fg9tRh • Aug 11, 2013

4 partitions, not 3.

/ - 40 GB is like 'whoa! enough!'
/boot - 450 MB
/home - As per your use
SWAP Area - 2x RAM

Sanyam KhuranaI have 4 GB of RAM, and I think it's enough, but still if I want to allocate some SWAP memory, how much should I allocate ?
Go for 6, not a single byte more.

I have 750 GB HDD

So, for root directory, 40 GB, /boot 450 MB, and I want to have one more for all the stuff, like around 250 GB- 300 GB.

For what is /home used for..?
