Xorg uses a configuration file called nf and files ending in the suffix. Note: Arch supplies default configuration files in /usr/share/X11//, and no extra configuration is necessary for most setups. Instead, the X server is started with either a display manager or xinit. The Xorg(1) command is usually not run directly. RDNA 2), see wikipedia:List of AMD graphics processing units. Radeon RX 6800) to GPU architectures (e.g. The exceptions to this rule are recent GPUs (especially NVIDIA GPUs) not supported by open source drivers.įor a translation of model names (e.g. Xorg should run smoothly without closed source drivers, which are typically needed only for advanced features such as fast 3D-accelerated rendering for games.

#AC COMPOSITOR DRIVERS#
Other video drivers can be found in the xorg-drivers group.
#AC COMPOSITOR DRIVER#
In order for video acceleration to work, and often to expose all the modes that the GPU can set, a proper video driver is required: If vesa is not found, Xorg will fall back to kernel mode setting, which includes GLAMOR acceleration (see modesetting(4)).If that is not found, it searches for vesa ( xf86-video-vesa), the generic driver, which handles a large number of chipsets but does not include any 2D or 3D acceleration.If it cannot find the specific driver installed for the hardware (listed below), it first searches for fbdev ( xf86-video-fbdev), which does not include any 2D or 3D acceleration.Xorg searches for installed drivers automatically: You can search the package database for a complete list of open-source video drivers: However, userland support is required for OpenGL and 2D acceleration in X11.įirst, identify the graphics card (the Subsystem output shows the specific model): The Linux kernel includes open-source video drivers and support for hardware accelerated framebuffers. They are pointed out in the relevant sections.įinally, an xorg group is also available, which includes Xorg server packages, packages from the xorg-apps group and fonts. Xorg can be installed with the xorg-server package.Īdditionally, some packages from the xorg-apps group are necessary for certain configuration tasks. 8.12 Xorg-server Fatal server error: (EE) AddScreen/ScreenInit.8.11 Invalid MIT-MAGIC-COOKIE-1 key when trying to run a program as root.8.9 A green screen whenever trying to watch a video.8.8 X failed to start: Keyboard initialization failed.8.6 Recovery: disabling Xorg before GUI login.
