Install Xubuntu Desktop in Ubuntuĭuring the installation, you will be required to select a display manager. The installation size, in my case, came to about 357 MB. The command also installs the XFCE environment and additional software packages that will be required by Xubuntu. Once the repositories are refreshed, install the Xubuntu desktop environment from the xubuntu-desktop meta-package as shown. Let’s get started by updating the package lists of your system.
In this guide, we focus on how you can install Xubuntu 20.04 desktop on Ubuntu. Xubuntu is, therefore, an ideal environment to turn to if you want to speed up your PC particularly if you are running a system with low computing specifications. It’s highly customizable and is kind on the computing resources such as CPU and RAM. Xubuntu is stable and relatively lightweight compared to the GNOME desktop environment which ships with Ubuntu 18.04 and later versions. One of the desktop environments that you can use to add some oomph and improve your user experience is the Xubuntu desktop environment. The choice is usually entirely up to you.
You can have multiple Desktop environments installed on your Linux system or you can decide to remove others and remain with one. If you are using a system with a graphical user interface, you can tweak almost anything – the desktop background, wallpaper, icons, and even installing a different desktop environment to have a change in the look-and-feel. To produce this information, compile the program with -g (along with the -pg option explained earlier) and run the gprof command with the -A command line option.One of the wonderful things about the Linux operating system is its vast array of customization options. Using gprof, you can also produce an annotated source listing that gives an idea about the number of times each line of the program was executed.An external tool by the name of gprof2dot can be used to convert the call graph from gprof into graphical form.So, make sure that your program has sufficient privileges to create a file in the current directory. The "gmon.out" file is always created in the current working directory.The file is not produced when the program either exits by calling the _exit() function or abnormally terminates due to an un-handled signal. To write the gmon.out file properly, your program must exit normally.To turn off the details, use the -b command line option with the gprof command. Note that the detailed explanation of these fields is present in the file containing profiling information (prof_output in this case) and is generated each time the profiler is run.
