I'm using Gnome now and want to install XFCE. Nothing complicated but just curious - do all applications, installed previously on Gnome will be also removed or they would work on XFCE properly after installing XFCE and removing Gnome ?
OS: Linux Mint 7
Don't uninstall Gnome, just select XFCE in the graphical login screen
You might lose functionality in any desktop widgets that were using Gnome, but in general, all of your application using GTK should not in any way be affected by what desktop environment you are using.
At least under Ubuntu, I am fairly sure that uninstalling Gnome should only affect the desktop environment, it should not remove any applications that are not explicitly tied to the Gnome desktop.
Installing XFCE is easy : as root, run:
yum groupinstall XFCE
In my experience, all gnome applications will work with XFCE. However, you should make sure that XFCE launches the appropriate services for these at startup. Navigate to Menu –> Settings –> Sessions & Startup. On the “Advanced” tab, select the appropriate checkbox.
There is no need to uninstall GNOME. The login screen will allow you to select one or the other.

I am new to PopOS! I have customized my desktop appearance except TOP BAR. I want to change this top bar panel. Is there any solution?
I have found the the solution with the installation of gnome tweak tools and extentions application. These makes the customization easier as it is on Ubuntu. I have also install plasma-desktop and from there I have installed all the themes I need. Without plasma desktop you can make the same but a bit difficult.
You can install gnome-tweak-tools from your shop where you get all the application.
Again most of the case extensions application could be installed in your system. Other than you can install this from shop also like gnome-tweak-tools.
In order to install plasma-desktop run this command on your terminal sudo apt-get install plasma-desktop
Then restart your system and select plasma desktop while sign in with your account. You will see a gear button at bottom right of you sign in screen. From there you have to select them.
In plasma desktop you have to go to settings and there you will get all the settings. For more customization you can follow YouTube tutorial.
Then logout from plasma desktop and in you PopOS desktop open tweak application to select the theme from appearance section.
Here is my customization:

As I wanted to learn Linux better, after using Fedora for a while I installed Arch Linux. Install was ok and working fine. But while I was installing KDE desktop environment, I didn't choose default(all) option, rather I choose randomnly a number for every step. KDE got installed and working. However I didn't used KDE before. I'm suspecting everything didn't installed. Did I made mistake choosing a random option instead choosing default? Can I install those packages for KDE?
It's recommended to choose "all" from the group plasma under Pacman to have a full working desktop environment.
But, not choosing "all" is not a mistake at all.
You can at any time install the package you want one by one with:
pacman -S nameOfPackage
or install all non-installed packages from plasma with:
pacman -S plasma

What's the difference between
1.installing Ubuntu and changing its desktop to KDE or direct installing kubuntu
2.installing Ubuntu and changing its desktop to XFCE or direct installing xubuntu
3.installing Ubuntu and changing its desktop to LXDE or direct installing lubuntu
4.installing Ubuntu and changing its desktop to mate or direct installing Ubuntu mate
5.installing Ubuntu and changing its desktop to gnome or direct installing gubuntu
Please help... I am confused..
They're all Ubuntu-based distros with different tweaks. Each distro runs on the same Linux kernel, so they're the really same for most intents and purposes. The obvious difference, as you have stated, is the desktop manager installed on each one, so a different look and feel. However, each of them also comes with different packages pre-installed. Each distro may ship with different video viewers, photo viewers, email clients, photo editors, and so on.
Each one will also consume different amounts of RAM, CPU, and power.
For more information, this post has very good tables and graphs to compare the distros: http://mylinuxexplore.blogspot.com/2014/11/ubuntu-1410-vs-kubuntu-1410-vs-xubuntu.html
This question should probably be asked on https://askubuntu.com/ but i'll answer it anyway. When installing Ubuntu you are greeted with a unity desktop meaning that all the unity package dependencies have been installed. If you were to install KDE on ubuntu (which is totally fine) you would still be left with unity desktop installed on your system. This is not ideal for computers with low storage or resources which is why different flavours of ubuntu have been released, aka kubuntu, ubuntu MATE. When installed these operating systems will only include the packages needed to run their own desktop (among other things like apt)

I need to make use of Firefox for web scraping. I am using WWW::Mechanize::Firefox. So I will need to install Firefox and Mozrepl however I am installing on a vps that does not have a GUI desktop environment and I am running into problems that Firefox requires a GUI/graphics driver.
The perl script will be run with a cronjob.
How can I do this?
From the documentation (WWW::Mechanize::Firefox::FAQ):
Do I Need An X Session To Run Firefox?
Yes.
If you run a unixish operating system, like OSX or Ubuntu or some
other Linux distribution, then Firefox will connect to your X server
and display a window there. If you do not want Firefox to actually
display on your monitor, many people have had success by running
Firefox on another X server separate from the main X server, like
Xvfb.
Personally, I would prefer to have a "headless Firefox" that does not
need a windowing environment. So far, I am unaware of this actually
existing.
So yes, you need to have an X session available.
Enable XForwarding, with ssh, so you can view the remote GUI desktop on your local machine. Then install Firefox via package management, then install MozRepel within Firefox. Once this is done ensure the MozRepel plugin is enabeled. Then use cpan to install the rest:
cpan WWW::Mechanize::Firefox

I've just installed Arch Linux and installed the gnome package (Note: Not gnome-extra)
I open Gnome using the xinit gnome-session command, as I have already installed X Window.
When I run that command, Gnome opens up and I'm presented with a white terminal titled "login". However, nothing I do in this terminal actually does anything. No commands work, nothing.
Could someone help me figure out what I'm doing wrong? There have been a few questions around similar to this, however none that have been properly answered.
Thank you!
After installing gnome session you need to append
exec gnome-sssion
at the end of your .xinitrc file located at your home.
when you get the login: prompt enter your username and then your password.
Once you're logged in type startx to start gnome session
Solved! I hadn't set Gnome to startup automatically, so when you login to Arch Linux using your standard root login. Check that gnome is installed and works (Use: xinit gnome-session).
Create an account by going to Settings, Users, Create the account as Administrator. Logout of Gnome Log back in as root to your Arch Linux CLI Use the command: systemctl enable gdm The next time you reboot, you should be presented with the Gnome Login screen.
