Ebuilds:
Previously, the nouveau ebuilds where in the nouveau overlay, which is now unmaintained. Use the x11 overlay instead, which is also availiable via layman
Recommended ebuilds:
x11-base/nouveau-drm (from git)
x11-drivers/xf86-video-nouveau (from git)
x11-libs/libdrm (from git)
The x11 overlay also has a mesa git ebuild, which contains the gallium based nouveau 3d driver, but it is still in a very early stage and using it is discouraged and unsupported
Unmaintained ebuilds:
Additionally, the now unmaintained nouveau overlay still contains the renouveau and mmio-trace utilities, which you will need if you want to help the development
x11-misc/renouveau
dev-util/mmio-trace
These ebuilds do not have any keyword, as it is usual with cvs/svn/git releases. To be able to install them, you have to mark them with ** in package.keywords.
These are the steps which are necessary in order to get the nouveau driver working on gentoo:
- Disable the nvidia proprietary kernel module.
eselect opengl set xorg-x11
- Make sure you have USE="dri" and VIDEO_CARDS="nouveau"
emerge -va nouveau-drm libdrm xorg-server xf86-video-nouveau
- Make sure you use the overlay ebuilds. You may have to unmask them.
- xorg-server recompilation is sometimes necessary after DRM changes, but not always. If you are not sure, re-emerge it
- Update xorg.conf to use driver "nouveau".
modprobe drm
modprobe nouveau
- startx
No, you will not have accelerated 3D support.
Not yours.
