From b2e564515a811c75ed9bd30969bc48ac4eadebfb Mon Sep 17 00:00:00 2001 From: Ludovic Courtès Date: Mon, 18 Mar 2019 22:56:13 +0100 Subject: services: xorg: Define an record type. * gnu/services/xorg.scm (): New record type. (xorg-configuration-file): Remove. (xorg-wrapper): Remove #:modules, #:configuration-file, and #:xorg-server; add optional 'config' parameter instead. Adjust accordingly. (xorg-start-command): Likewise. * doc/guix.texi (X Window): Document 'xorg-configuration'. Update 'xorg-start-command' documentation. Remove 'xorg-configuration-file' documentation. --- doc/guix.texi | 118 ++++++++++++++++++---------------------------------------- 1 file changed, 36 insertions(+), 82 deletions(-) (limited to 'doc/guix.texi') diff --git a/doc/guix.texi b/doc/guix.texi index 5789b3b99b..b49f651562 100644 --- a/doc/guix.texi +++ b/doc/guix.texi @@ -13352,99 +13352,53 @@ type @code{}. @end example @end deffn -@deffn {Scheme Procedure} xorg-start-command @ - [#:modules %default-xorg-modules] @ - [#:fonts %default-xorg-fonts] @ - [#:configuration-file (xorg-configuration-file @dots{})] @ - [#:xorg-server @var{xorg-server}] - [#:xserver-arguments '("-nolisten" "tcp")] -Return a @code{startx} script in which @var{modules}, a list of X module -packages, and @var{fonts}, a list of X font directories, are available.
