From: r0man <roman@burningswell.com> * gnu/services/xorg.scm (xorg-wrapper): Support xorg server input rewriting. This patch adds support for proper xorg server input rewriting. It uses the lookup-package-direct-input procedure to configure the X server paths dynamically, instead of always using the hard coded package. Something like this is now possible: (define other-mesa (package-input-rewriting/spec `(("mesa" . ,(const other-mesa))))) (xorg-configuration (xorg-configuration (server (other-mesa xorg-server)))) Without this patch the X server would still be configured with mesa (causing version issues), and not with other-mesa (as per the input rewrite). --- gnu/services/xorg.scm | 23 ++++++++++++++++++++--- 1 file changed, 20 insertions(+), 3 deletions(-)
