Operation (Compaq Tru64 UNIX)

3.Find the line containing PowerStorm 300/350 X server command-line arguments. Search for the text “ PowerStorm 300/350 Server args start” and proceed to the next line where the arguments reside.

4.Append the –screenargument and optionally the –vsyncargument to the arguments already present. The screen argument specifies the width and height of the screen in pixels, and the vsync argument specifies the refresh rate in Hz. For example, to set the resolution to 1280x1024 at 85 Hz, alter the arguments to appear as below:

! PowerStorm 300/350 Server args start

-pn –su –bs –nice –2 –screen 1280x1024 –vsync 85

! PowerStorm 300/350 Server args end

5.Save your changes to the /var/X11/Xserver.conf file.

6.Restart the server:

> /sbin/init.d/xlogin restart

7.2.2Synchronizing Buffer Swaps

Double-buffer swaps may be synchronized with vertical retrace to avoid visual “tearing” effects. For improved performance, the default behavior is not to synchronize the buffer swaps to the vertical retrace.

Tearing and flickering can occur for a combination of reasons:

∙Many large triangles are being processed.

∙A large window is being used.

∙High resolution and refresh rate values are defined.

Most applications do not experience visual tearing and could take advantage of the higher frame rates and better performance available when no synchronization is used. Therefore, you should try using this mode.

If unwanted visual effects do occur, however, use the tear-free double-buffering mode, and choose the highest vertical refresh rate supported by your monitor at your chosen resolution (see Section 7.2.1).

To enable double-buffer swap synchronization, follow these steps:

1.Login to the system as root. Ensure that no other user is currently working locally at the X console or connected remotely to the X server. You may choose to reboot the system in single-user mode before continuing.

2.Edit the file /var/X11/Xserver.conf. Save a backup copy.

300 specifications

The Compaq 300, introduced in the early 1990s, marked a pivotal moment in personal computing, combining cutting-edge technology with user-centric design. This desktop system was targeted at both business professionals and home users, reflecting the growing demand for powerful yet affordable computing solutions.

One of the main features of the Compaq 300 was its robust Intel processor. It originally shipped with various configurations of Intel's 80486 microprocessor, which provided a significant performance boost over its predecessors. The 486 architecture enabled users to run more complex applications, enhancing productivity and making it suitable for tasks ranging from word processing to graphics editing.

In terms of memory, the Compaq 300 supported up to 16MB of RAM, which was substantial for its time, allowing seamless multitasking of programs. The system typically included a 120MB IDE hard drive, which facilitated ample storage for documents and software, a critical aspect for users who needed to manage large volumes of data.

The Compaq 300 featured an integrated graphics card based on the popular VGA standard, enabling clear display quality for applications and gaming. Notably, its 14-inch CRT monitor that accompanied the system offered crisp visuals and an optimal viewing experience for users.

Another characteristic of the Compaq 300 was its expandability. The desktop came equipped with several expansion slots, allowing users to easily add components such as sound cards, network cards, or additional storage drives. This feature provided users with the flexibility to upgrade their systems as technology evolved, ensuring longevity in a rapidly changing landscape.

The Compaq 300 also showcased advanced connectivity options for its time. It included multiple serial and parallel ports, providing versatile connectivity with peripherals like printers, scanners, and modems. This adaptability was crucial, especially as businesses began to integrate more technology into their operations.

Durability and reliability were hallmarks of Compaq's design philosophy, and the Compaq 300 was no exception. Its solid construction and dependable components appealed to users who required a trustworthy system for daily tasks.

Overall, the Compaq 300 epitomized the intersection of performance, expandability, and reliability in desktop computing. Its innovative features and thoughtful design paved the way for future developments in the personal computer industry, making it a noteworthy entry in the history of computing technology.
