'Twas brillig, and Anssi Hannula at 05/12/11 06:09 did gyre and gimble:
> Hi!
> 1. nouveau
> I propose to move nouveau DRI drivers from libdri-drivers-experimental
> to libdri-drivers.
> Fedora moved them out of -experimental in last January, Ubuntu in last
> June, OpenSUSE in July (though OpenSUSE doesn't have the legacy
> nouveau_vieux DRI driver at all), and Debian a week ago.
> I've been running with it for the last week or so with no problems on my

Seems sensible. I've not got any NV h/w but this seems like the Right
Thing to Do(tm).

> 2. swrastg
> It seems we have both swrast_dri.so and swrastg_dri.so in libdri-drivers
> package.
> swrast_dri.so is the traditional SW rasterizer used when there is no HW
> support.
> swrastg_dri.so is the Gallium3d-based rasterizer which is considerably
> faster.
> However, actually only swrast_dri.so is used, so should we:
> 1) switch to swrastg, drop swrast (Fedora in Nov 2010)
> 2) keep it as is, unused (~4 MB)
> 3) move swrastg to libdri-drivers-experimental (Ubuntu in Jun 2010,
>    Debian a week ago) which nouveau is probably moving out of
> 4) drop swrastg completely for now (seemingly OpenSUSE)

On balance, I ultimately prefer 3 with your xserver patch, Either that or 1.
