In my newly installed ubuntu 18.04 I have all the icons and fonts for all applications are extremely small. For example, below is a screenshot from my pinta application, tools section I can hardly see whats in there. How can I make it normal for all applications.
I am using ubuntu 18.04 on Dell xps 13. Recently I bought a bluetooth headphone. It automatically connects to laptop bluetooth. It worked 3-4 days perfectly okay. Then I started to have problem that, every now and then my wifi would disconnect automatically while using the headphone. For last couple of days, if I turn on my headphone then my laptop wifi gets disconnected within 3-5 minutes. Even restarting laptop does not work. I have to turn off the headphones and then restart my laptop then it works. Is there any solution for this weird problem.
I use Terminator terminal. As you can see from the screenshot below, everywhere it shows the directory names. Instead of showing whole directory names, I want it to show only the last directory name i.e ecommerce in this case. Is there a way to do this?
Whenever I login to skype I get this keyring message. I don't remember setting any keyring or don't even know what it is. I can login to my kubuntu with my password but to unlock keyring same password does not work. So how can I unlock this keyring or completely remove/disable this keyring option?
None of the existing solutions work for Kubuntu, either those solutions are old or the menu doesn't exist in Kubuntu.
How can I create a shortcut to open kde konsole at current location? For example, if I am in Download directory, I want the konsole to start from that location. Is it possible using a shortcut? I am using KDE 18.04
I have installed and customized my KDE desktop in one of my laptop. Now I have another laptop where I also installed KDE. Since I have already did the customization in one laptop already, I want to copy the system settings from there to the newly installed desktop so that I don't have to do the customizations again.
Is there any way I can copy the system settings from one laptop to another?
When I run this command
sudo tasksel install kubuntu-desktop
My terminal gives following line and exit kde install although I have xserver-xorg already installed
xserver-xorg install
How can I install KDE desktop on my ubuntu 18.04. Currently I have gnome desktop.
I have a 5.1 home theater with the ports as the figure shows. How can I connect it to my laptop? 
I just installed ubuntu and installed all the necessary softwares that I normally use, for example browsers, editors etc. Also I did all the customizations that I like and so on.
Now I want to make an image/backup(I don't know what its called) of my current system. Next time, if I want to to install ubuntu on a new pc, I want to use my current image/backup so that all the software installation, customization are already there. So I don't want to do the installation of the softwares, customizations everytime I install ubuntu.
Finally, it would be like taking a snapshot of my current state of the system and when I install another one from this snapshot, new one should be exactly like the same as the current one. Hope I explained properly. Anyway, is there any way to do this?

I can not access certain sites like youtube, facebook etc. I tried to ping www.youtube.com but it gives me ping: www.youtube.com: Name or service not known. When I try to ping without www it works ping youtube.com,
PING youtube.com (216.58.206.14) 56(84) bytes of data.
64 bytes from fra16s20-in-f14.1e100.net (216.58.206.14): icmp_seq=1 ttl=52 time=62.7 ms
Same happens for facebook. I tried both browser firefox and chrome, same problem. So what is wrong here and how to solve it?
As you can see in the image below, there are 3 instances of Firefox and file manager is open and all of them are grouped together. But I do not want them to be grouped. I looked into unity tweak tool and Ubuntu system settings but I could not find how to ungroup this.
Is there any way I can do this? I am using Unity 7.5 and Ubuntu 17.

I have installed apache using following command
sudo apt-get install apache2
After that I start the server with this command
sudo systemctl restart apache2
This did run the server and everything worked perfectly. But after the first time, I restart the server using the same command and this time localhost keeps loading forever. No page or anything is shown in localhost. It just keeps loading. Why this is happening and whats the solution?
I just installed xampp in my ubuntu 16.04 and now my server is not running. If I run this command to start apache sudo systemctl start apache2 I get this error Failed to start apache2.service: Unit apache2.service not found. Another problem is when I run php -v I get this message
