[gentoo-user] Tracing use flags - how to?

[gentoo-user] Tracing use flags - how to?

[Helmut Jarausch]

Hi,

this might well we a FAQ but I couldn't find it.

In the process of upgrading to xorg-server-1.8.2 I'd like to remove
the 'hal' use flag.
I have removed it in /etc/make.conf and added 'udev' instead.
The xorg-server definitely doesn't have this use flag set in 
/etc/portage/package.use

Still, emerge -vp x11-base/xorg-server shows that it is going to use 
the 'hal' but not the 'udev' flag.

How to find out where this comes from.

I haven't found anything in 'use.mask' in my profile
default/linux/amd64/10.0/desktop

Many thanks for a hint,
Helmut.

Apparently, though unproven, at 09:18 on Thursday 28 October 2010, Helmut 
Jarausch did opine thusly:

That will remove it globally from the entire system, which might not be what 
you want. IIRC k3b needs hal for instance to work correctly.

I usually read the ebuilds and grep directly through files to find this kind 
of stuff :-) I find it easier than remembering commands.

The xorg-server ebuild says:
IUSE_SERVERS="dmx kdrive xorg"
IUSE="${IUSE_SERVERS} doc hal ipv6 minimal nptl tslib +udev"

So it uses all those flags, and "udev" is on by default unless you explicitly 
say otherwise somewhere.

Post the USE section from emerge --info, the output from 
emerge -vp x11-base/xorg-server.
the output from 
grep -r udev /etc/portage/*
grep -r hal /etc/portage/*

and let's take it from there.

Finding stuff in profiles is tricky, you have to search upwards through the 
directories, not downwards.

Thanks, I've added it again.

Unfortunately, that's too late now.
Meanwhile I have add 
x11-base/xorg-server -hal
to /etc/portage/package.use

That didn't show any hal entries.

Many thanks, Alan.
Meanwhile, upgrading to xorg-server-1.8.2 went smoothly and 
I've removed  /etc/hal/fdi/policy/x11-input.fdi
where I had some settings for the keyboard and the mouse.

Looks like you hit the sweet spot of success :-)
