Usplash
Usplash is a software project in the Ubuntu community. Historically, scrolling text "verbose mode" has typically appeared on Linux computers during boot. Usplash replaces the scrolling-text screens with a graphical splash screen. It was designed to replace Bootsplash, which did the same thing on the kernel space level. Since usplash operates in user space, it can be updated without recompiling the kernel. Usplash uses the Linux framebuffer interface or, alternatively, direct VESA access to display the splash screen. In Ubuntu 9.10 "Karmic Koala", Usplash is only used in the preliminary stages of booting, after which XSplash takes over. In Ubuntu 10.04 LTS "Lucid Lynx", Usplash has been fully replaced by Plymouth, which uses Direct Rendering Manager (DRM) and KMS driver. See also * Plymouth Plymouth () is a port city and unitary authority in South West England. It is located on the south coast of Devon, approximately south-west of Exeter and south-west of London.

Bootsplash
A bootsplash, also known as a bootscreen, is a graphical representation of the boot process of the operating system. A bootsplash can be a simple visualization of the scrolling boot messages in the console, but it can also present graphics or some combinations of both. Unlike splash screens, a bootsplash is not necessarily designed for marketing purposes; it can be intended to enhance the experience of the user as eye candy, or provide the user with messages (with an added advantage of color-coding facility) to diagnose the state of the system. Microsoft Windows All versions of Microsoft Windows feature a boot screen, which is loaded during the startup process. With extra, third-party utilities, it is possible to replace the default Windows boot screen with custom images, text, and/or animations. Windows Vista In Windows Vista, the default boot screen is represented by a green indeterminate progress indicator. The boot screen can be changed so that it displays a static im ...

Debian
Debian (), also known as Debian GNU/Linux, is a Linux distribution composed of free and open-source software, developed by the community-supported Debian Project, which was established by Ian Murdock on August 16, 1993. The first version of Debian (0.01) was released on September 15, 1993, and its first stable version (1.1) was released on June 17, 1996. The Debian Stable branch is the most popular edition for personal computers and servers. Debian is also the basis for many other distributions, most notably Ubuntu. Debian is one of the oldest operating systems based on the Linux kernel. The project is coordinated over the Internet by a team of volunteers guided by the Debian Project Leader and three foundational documents: the Debian Social Contract, the Debian Constitution, and the Debian Free Software Guidelines. New distributions are updated continually, and the next candidate is released after a time-based freeze. Since its founding, Debian has been developed openly ...

Video Electronics Standards Association
VESA (), formally known as Video Electronics Standards Association, is an American technical standards organization for computer display standards. The organization was incorporated in California in July 1989To retrieve the information, search for Entity Number C1645094. and has its office in San Jose. It claims a membership of over 300 companies. In November 1988, NEC Home Electronics announced its creation of the association to develop and promote a Super VGA computer display standard as a successor to IBM's proprietary Video Graphics Array (VGA) display standard. Super VGA enabled graphics display resolutions up to 800×600 pixels, compared to VGA's maximum resolution of 640×480 pixels—a 56% increase. The organization has since issued several additional standards related to computer video displays. Widely used VESA standards include DisplayHDR, DisplayPort, and Flat Display Mounting Interface.

Booting
In computing, booting is the process of starting a computer as initiated via hardware such as a button or by a software command. After it is switched on, a computer's central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed. This may be done by hardware or firmware in the CPU, or by a separate processor in the computer system. Restarting a computer also is called rebooting, which can be "hard", e.g. after electrical power to the CPU is switched from off to on, or "soft", where the power is not cut. On some systems, a soft boot may optionally clear RAM to zero. Both hard and soft booting can be initiated by hardware such as a button press or by a software command. Booting is complete when the operative runtime system, typically the operating system and some applications,Including daemons. is attained. The process of returning a computer from a state of sleep (suspension) does not involve bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KMS Driver
The Direct Rendering Manager (DRM) is a subsystem of the Linux kernel responsible for interfacing with GPUs of modern video cards. DRM exposes an API that user-space programs can use to send commands and data to the GPU and perform operations such as configuring the mode setting of the display. DRM was first developed as the kernel-space component of the X Server Direct Rendering Infrastructure, but since then it has been used by other graphic stack alternatives such as Wayland. User-space programs can use the DRM API to command the GPU to do hardware-accelerated 3D rendering and video decoding, as well as GPGPU computing. Overview The Linux kernel already had an API called fbdev, used to manage the framebuffer of a graphics adapter, but it couldn't be used to handle the needs of modern 3D-accelerated GPU-based video hardware. These devices usually require setting and managing a command queue in their own memory to dispatch commands to the GPU and also require management ...

Plymouth (software)
Plymouth is a free application which provide bootsplash for Linux, which handles user interaction during the boot process. Plymouth supports animations using Direct Rendering Manager (DRM) and the KMS driver and is bundled into initrd which enables it to be launched before the file system is mounted. The program is named after Plymouth Rock, a name which symbolizes the program's role as a first point of entry for users to interact with a computer system. ''Plymouth'' was first included in Fedora 10 "Cambridge" shipped on November 25, 2008 where it replaced Red Hat Graphical Boot (RHGB). Ubuntu includes it in the Ubuntu 10.04 LTS "Lucid Lynx" release shipped on April 29, 2010. Mandriva switched from Splashy to Plymouth with versioAdélie (2010.0) History The development of Plymouth began in May 2007 and began under the leadership of Ray Strode. However, there was little support for this project until early 2008, when the decision to introduce Plymouth into Fedora 10 gave a bo ...

User Space
A modern computer operating system usually segregates virtual memory into user space and kernel space. Primarily, this separation serves to provide memory protection and hardware protection from malicious or errant software behaviour. Kernel space is strictly reserved for running a privileged operating system kernel, kernel extensions, and most device drivers. In contrast, user space is the memory area where application software and some drivers execute. Overview The term user space (or userland) refers to all code that runs outside the operating system's kernel. User space usually refers to the various programs and libraries that the operating system uses to interact with the kernel: software that performs input/output, manipulates file system objects, application software, etc. Each user space process normally runs in its own virtual memory space, and, unless explicitly allowed, cannot access the memory of other processes. This is the basis for memory protection in today' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Framebuffer
The Linux framebuffer (fbdev) is a linux subsystem used to show graphics on a computer monitor, typically on the system console. It was designed as a hardware-independent API to give user space software access to the framebuffer (the part of a computer's video memory containing a current video frame) using only the Linux kernel's own basic facilities and its device file system interface, avoiding the need for libraries like SVGAlib which effectively implemented video drivers in user space. In most applications, fbdev has been superseded by the linux Direct Rendering Manager subsystem, but as of 2022, several drivers provide both DRM and fbdev APIs for backwards compatibility with software that has not been updated to use the DRM system, and there are still fbdev drivers for older (mostly embedded) hardware that does not have a DRM driver. Applications There are three applications of the Linux framebuffer: * An implementation of text Linux console that doesn't use hardware te ...
