Xorg is an open source implementation of the X Window System.
There are many ways to get the X server in Gentoo, however a common method is to emerge one of the two packages:
- x11-base/xorg-server - Installs the necessary components for a minimally operational X server.
- x11-base/xorg-x11 - Installs a large Xorg software suite.
As seen from the descriptions above, those who desire a more minimal X server implementation should choose the first package.
USE flags for x11-base/xorg-server X.Org X servers
||Enable extra debug codepaths, like asserts and extra output. If you want to get meaningful backtraces see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces|
||Use elogind to get control over framebuffer when running as regular user|
||Install a very minimal build (disables, for example, plugins, fonts, most drivers, non-critical features)|
||!!internal use only!! Security Enhanced Linux support, this must be set by the selinux profile or breakage will occur|
||Enable setuid root program, with potential security risks|
||Enable use of systemd-specific libraries and features like socket activation or session tracking|
||Enable dependencies and/or preparations necessary to run tests (usually controlled by FEATURES=test but can be toggled independently)|
||Enable virtual/udev integration (device discovery, power and storage device support, etc)|
||Enable libunwind usage for backtraces|
||Build Security extension|
||Build the Xephyr server|
||Build the Xnest server|
||Build the Xorg X server (HIGHLY RECOMMENDED)|
||Build the Xvfb server|
This metapackage does not have any USE flags of its own.
The X USE flag
Just the necessary components:
emerge --ask x11-base/xorg-server
The full Xorg suite via the meta package:
emerge --ask x11-base/xorg-x11
Getting a working graphical environment (including popular desktops like KDE and Gnome) requires additional configuration before emerging one of these packages. See the more extensive Xorg Guide for details.
X server starts and dies unexpectedly with no errors
Problem: Running startx will start the X server, however it will immediately die without any errors (searching "
EE" in /var/log/Xorg.0.log returns no related results).
Cause: an empty .xinitrc file exists for the user who is running the startx command, so the X server is starting, then stopping because there is nothing left for it to do.
Resolution: Either remove the .xinitrc file or define a window manager inside it.
Blockers when updating xorg-server with xorg-drivers
When an update is available for xorg-server, it is possible that a normal -up world command will produce blocker messages with xorg drivers. When this happens, rebuilding x11 modules can help proceed with the update Ex:
emerge -av1 xorg-server @x11-module-rebuild
