Re: [gentoo-dev] New eselect news item for X11 on alphas

Hi!
See below. For a little more background:
http://blog.i-no.de/archives/2009/06/28/index.html#e2009-06-28T13_54_50.txt
Also note the glibc part of the same post. Maybe that'd warrant a news
item, too? What do the toolchain guys think?
As for my news item, what I'm not entirely sure about are the Displa-If-
headers (What I'm aiming for is to reach people who have installed *either*
xorg-x11 (and thus -server) or just xorg-server on any alpha profile)
Also, the last paragraph might reek a bit of politics, but I'm quite
comfortable with placing pressure on the Xorg guys via users.

Recent versions of xorg's X11 require kernel support to access PCI and
AGP graphic cards. This support has only recently been added to the
Linux kernel (vanilla-sources-2.6.30 and gentoo-sources-2.6.29-r5).
Thus, you will need to run a recent enough kernel to use recent versions
of X11 on an alpha. If you only start programs on your alpha, but the
display is on another machine, no upgrade is necessary.
Furthermore, not all graphics card drivers have been updated to work
with the newer X server API. One example is the glint driver used for
Permedia cards. The upstream developers have been informed about this,
but nothing has happened so far.

According to GLEP 42:
"The algorithm used to determine whether a news item is 'relevant' is as
follows:
* For each Display-If- header type which occurs at least once:
** The news item is not relevant if none of the headers of this type
are successfully matched.
* Otherwise the news item is relevant."
I understand it like a OR match for every type, which are linked by
AND.

There is also Display-If-Keyword (for the sake of completeness
in this post).

Add sys-kernel/ categories, please.

"...but no fixes are available yet, please see ."
Maybe you could mention the 1.5 upgrade guide again.

I think it is correct: All Display-If headers of the same type are
combined by logical OR.
The "Display-If-Installed: x11-base/xorg-x11" may be redundant though,
since xorg-server is a dependency of xorg-x11.

Hi!

Imagine a trembling lower lip with that :)
Fixed both, new version below. Thanks again.

Yeah, redundant.
