Bug 306701 – "The X Server Configuration HOWTO" doesn't tell you when to set USE="hal"

• Product: [OLD] Docs on www.gentoo.org
• Status: RESOLVED INVALID

[Description Adam 2010-02-24 19:25:56 UTC]

When I followed The X Server Configuration HOWTO:
 
http://www.gentoo.org/doc/en/xorg-config.xml

X wouldn't work because I didn't have hal installed and running.  It seems the default USE variable doesn't include hal.

Is hal really needed to run X?  Or is it always needed on some machines?  I don't mind that it isn't installed by default, but the documentation should be clearer about whether you need to set USE="hal" and/or emerge hal before doing emerge xorg-server.

Also, perhaps the section on hal should go before the section telling you to emerge xorg-server?

The guide says "By default, Xorg uses HAL", which is definitely wrong.  I installed Gentoo from stage3-i686-20100126.tar.bz2.


Reproducible: Didn't try

AFAIK you only need this when using evdev.

[Comment 2 nm (RETIRED) 2010-02-25 07:01:41 UTC]

HAL is enabled by default, as it's what upstream preferred with this version, and what the Gentoo maintainers prefer.

So unless you change your USE flags, you'll get a HAL-enabled xorg-server, given that the desktop profile is set for HAL.

The doc already says to have HAL enabled:

[ebuild   R   ] x11-base/xorg-server-1.6.3.901-r2  USE="hal nptl xorg -debug

. . . you just missed it. The rest of the instructions refer to a HAL-enabled X, so it's not hard to guess when to do it.
