Bug 134087 – Information missing from the DRI howto documentation

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

[Description krudyard 2006-05-23 01:16:26 UTC]

Using gentoo-sources-2.6.16-r7 kernel.
http://www.gentoo.org/doc/en/dri-howto.xml
Seems at least one thing is missing from the guide: in order to emerge
x11-drm one must first set something like
VIDEO_CARDS="video_cards_radeon"
in the /etc/make.conf file.
Furthermore, when I simply set
VIDEO_CARDS="radeon"
as per the output of the emerge without any VIDEO_CARDS set, the x11-drm package did not compile. However it compiled successfully with
VIDEO_CARDS="video_cards_radeon"
None of these complications are hinted at in the guide.

Still, even after the installation of the x11-drm package using VIDEO_CARDS="video_cards_radeon"
the module was missing. No further hints as to what may be wrong are given in the howto.

What version of Portage are you using, what version/arch of x11-drm are you trying to emerge, and for what version of X11?

I am trying to emerge 

x11-base/x11-drm 20050502

for 

xorg-x11 6.8.2-r7

using 

portage 2.0.54-r2

Any progress on this? The new portage and X11 fully support the proper syntax now. Still a problem, or can this be closed?

I spoke to the guru of all things drm and X11 and modular X and video card checking (dberkholz++) on IRC, and he confirmed that you really shouldn't be setting the things you did.

Before emerging, you should have checked with "emerge -pvt" to see what variables the ebuild looks for in /etc/make.conf; that would tell you whether to do it by USE flags or by VIDEO_CARDS.

Next time, try emerge -pvt <package> ; it's quite a lifesaver.
