The X server, a fundamental component of the Linux graphics stack, has seen a new implementation in Assembly language. Frame, developed by Geir Isene, is a lightweight X11 server written in pure x86_64 Assembly [1]. This new server is part of Isene's quest to own his software, with the goal of achieving better battery life and a more efficient system [2]. Frame's design philosophy emphasizes simplicity and minimalism, with a codebase of approximately 20 thousand lines, significantly smaller than the 4 million lines of code in X11 [3].
The server is still in its early stages, with a long list of X protocol features left to implement, but it already runs a full desktop environment, including Firefox and GIMP [4]. Isene's approach to software development is centered around the idea of controlling and owning the software, with all his projects released into the Public Domain [5]. The development of Frame is not an isolated effort, as Isene collaborates with his buddy Claude to resolve issues and implement new features [6]. Frame's performance has been measured, with idle power consumption comparable to Xorg, but with significantly lower CPU usage [7].
The project's success can be attributed to Isene's dedication to simplicity and his willingness to learn and adapt, as evident in his exploration of hardware layers, cursor painting, and GPU handoffs [8]. Frame is an example of how a focused approach to software development can lead to innovative and efficient solutions.
