How to fix a Ubuntu blank screen while booting?

Published

on

There are millions of individuals all over the world who use the open-source operating system known as Ubuntu. On the other hand, users may on occasion experience a problem in which the screen goes black while the system is booting, making it more difficult for them to log into the system. In this post, we will investigate some of the most common factors that contribute to this issue, and then present many potential remedies that can assist in resolving it.

  • Problems with the Graphics DriverA problem with the graphics driver is one of the most common reasons why the Ubuntu screen goes black while the operating system is booting. The graphics driver is an integral part of the system because it is what makes still images and moving movies show up on the screen. During the process of booting the computer, if the driver is out of date or faulty, it may cause the screen to become blank. You might be able to fix this problem by making sure the driver for the graphics card is updated to the most recent version. To do this, go to the System Settings menu and choose “Software & Updates” from the drop-down menu. When you get to that screen, go to the option labeled “Additional Drivers,” and then choose the most recent version of the graphics driver.
  • Put the computer into safe mode. Booting Ubuntu into safe mode is another potential solution to the problem of the screen going blank while the operating system is starting up. Safe mode is a way to start up a computer that only loads the drivers and services that are needed. This makes it much simpler to identify and fix problems with the operating system. While the system boots up, holding down the Shift key will allow you to boot into safe mode. This will bring up the GRUB boot menu, where you may choose the “Advanced Options for Ubuntu” option from the list of available options. When you get to that screen, pick the “Recovery Mode” option, and then pick the “Safe Graphics Mode” option.
  • Turning off the protective splash screen. The splash screen is the screen that displays a logo and loading status while the system is booting up. It occurs while the system is starting up. But the splash screen can sometimes cause problems that prevent the system from starting up correctly. If you want to fix this problem, you can try disabling the splash screen by including “nomodeset” in the list of boot options in the GRUB menu. This should do the trick. In order to accomplish this, boot the system while holding down the Shift key and select the “Advanced Options for Ubuntu” option from the menu that appears. After reaching that screen, choose the “Recovery Mode” option, and after that, choose the “Root Console” option. When you are ready, enter the “/etc/default/grub” file and add “nomodeset” to the GRUB CMDLINE LINUX DEFAULT line. Do this after you have logged in. After that, you should execute the command “sudo update-grub” and then restart the machine.
  • Check the settings on your monitor. There is a problem with the display settings, which is another potential reason why the Ubuntu screen goes black while it is booting. Perform these checks to make sure that the monitor is set to the right input and is set up correctly. For example, if you are using a monitor with a fast refresh rate, you should make sure it is set to the right value. If you are using a dual-monitor setup, make sure that both monitors have the right settings and that they don’t interfere with each other in any way.
  • Try to fix the bootloader. During the boot process, if the bootloader has been corrupted in any way, the screen may not display anything. You can try to fix the bootloader by using the Ubuntu installation disc that can be used as a bootable drive. This should solve the problem. After that, when you put the installation DVD into your computer, you will need to restart the system. After getting to that page, choose the “Try Ubuntu” option, and then choose the “Install Ubuntu” option. When you get to that screen, pick the “Reinstall Ubuntu” option, and then click the “Continue” button after that. After the installation process is finished, the bootloader will have been automatically repaired, and you should be able to enter the system normally after it has finished.
  • ConclusionIn conclusion, there are a number of potential causes that could be causing your Ubuntu screen to go blank while it is booting, some of which include problems with the graphics driver or booting into safe mode.

What is Cloud Computing?

Published

on

The advent of cloud computing is widely regarded as one of the most important and game-changing developments in information technology to occur in the 21st century. It provides a platform that is versatile and scalable, meeting the requirements for computation and storage in a way that has transformed the way in which consumers and companies store data and access applications. In this piece, we will discuss what cloud computing is, its benefits, the various kinds of cloud computing services, and the important participants in the market for cloud computing.

What exactly is “computing in the cloud”?

The term “cloud computing” refers to a type of technology that, as opposed to storing, accessing, and processing data and programs on local servers or personal computers, it does so through the usage of the Internet. The transmission of computing services over the Internet is referred to as “the cloud.” This model gives users the ability to access and make use of the services whenever they want to. The use of cloud computing removes the requirement for businesses and individuals to purchase and maintain their own hardware and software infrastructure, which may be a time- and money-consuming process. Users can instead access these resources through the internet using any device that has an internet connection.

Advantages of utilizing cloud computing

The use of cloud computing has a number of advantages over more conventional computer models. The following are some of the most important advantages:

Scalability is a feature of cloud computing that enables businesses and people to adjust the number of computer resources they use based on their current requirements without having to purchase more hardware or software. This is especially helpful for businesses that encounter shifts in demand for the computing resources they possess.

The elimination of the need to make investments in and perform maintenance on a company’s hardware and software infrastructure is one of the primary drivers behind the huge cost reductions that may be provided by cloud computing to businesses and people. Additionally, cloud computing enables customers to only pay for the computing resources that they use, which might be a more cost-effective alternative to owning and maintaining specialized gear and software.

Accessibility: Users of cloud computing are able to access their data and applications from any device that has an internet connection. This accessibility makes it simpler for individuals and companies to operate from any location at any time.

Recovery from Disaster Cloud computing features built-in disaster recovery capabilities, enabling businesses and people to safeguard their data and apps in the case of a catastrophic event such as a natural or man-made catastrophe.

Security: Cloud computing providers make significant investments in the implementation of security measures to protect the data and applications of their customers. These providers are in a better position to implement security best practices than a great number of individual organizations and people.

Different Categories of Cloud-Based Service Types

Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service are the three main categories that can be used to describe cloud computing services in a general sense (SaaS).

Infrastructure as a Service (IaaS) is a model that makes it possible to access virtualized computing resources including virtual machines (VMs), storage, and networking through the use of the internet. By utilizing Infrastructure as a Service (IaaS), businesses and individuals are able to rent computing capabilities on an as-needed basis without having to make an initial investment in and ongoing maintenance of their own hardware.

Providers of “Platform as a Service” (PaaS) is an abbreviation for the platform as a service, and it refers to a service that offers a development platform for building, deploying, and managing applications and services. PaaS gives businesses and individuals access to the tools and resources necessary to build and deploy their own applications and services without requiring them to invest in and maintain their own hardware and software infrastructure. This frees up both time and money for application and service development.

Software as a Service, sometimes known as SaaS, is a model that delivers software to end users via the internet, typically in exchange for a recurring fee. Email, customer relationship management (CRM) systems, and office productivity software are all types of programs that fall under the category of software as a service.

Principal Participants in the Cloud Computing Industry

The market for cloud computing is comprised of a number of important firms, some of which include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud.

A renowned provider of cloud computing services, Amazon Web Services (AWS) offers a comprehensive range of infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS) options.

However, enterprises need to be aware of the issues that come along with using cloud computing because these challenges are linked with cloud computing. When data of a sensitive kind is kept in the cloud, one of the most significant issues is ensuring that the data is secure. This necessitates the establishment of comprehensive data management policies and practices within businesses, as well as comprehensive data security measures to guard against the occurrence of data breaches.

Another obstacle is making sure that the cloud computing services that a corporation relies on are dependable and can be used whenever they are required. This necessitates the implementation of backup strategies within businesses, such as disaster recovery plans, to ensure that mission-critical apps and data can be accessed even in the event that the core cloud computing infrastructure is unavailable.

In conclusion, it is essential for businesses to have a thorough understanding of the costs that are connected with cloud computing, as well as the potential influence that these expenditures may have on their entire budget for information technology. There is a possibility that using cloud computing services will be less expensive than using traditional computing methods; however, businesses still need to be aware of the costs associated with data storage and security.
