backtraced and compared the steps performed by Felix.
- xorg driver xf86-video-nouveau shipped by openSUSE as from jobermayr is
exactly or basically the same source code;
- libdrm is exactly or basically the same source code;
- not tried pscnv driver yet, but do not expect much from it (seems it is a
fork with tackles ttm architecture)
- the drm kernel modules (20110721.2009-2.3) use the build option
CONFIG_DRM_NOUVEAU_KMS=3Dy, which as far as I remember was set to 'n' in
the
Makefile from the Nouveau DRM wiki (although I did also try enabling that once
on the git source without achieving anything): in any case I did not touch the
kernel module, still using the already mentioned one from freedesktop snapshot
- however can anyone comment something on the above mentioned build option ?
what's that for exactly ?
- the drm kernel module shipped by jobermayr and tagged as 20110721.2009-2.3 on
openSUSE does ship separate vgaarb and vga_switcheroo which I have built into
the kernel but they are exactly the same version and code
- same as above for acerhdf which however is exactly the same version as in
latest kernel and it's not even very relevant to this problem
- same as above for wmi and mxm-wmi which however is exactly the same version
as in latest kernel
- same as above for acer-wmi (Acer WMI Laptop Extras, I have an Acer Aspire
5745G) which is not the same as in vanilla kernel 3.0.0-git4, I have not tried
it, it's not relevant, such module should be just for the functionality of
extra special keys on the keyboard
- glew is a different version, I also have the newer one installed (1.6.0) on
my system
- I do not have library Mesa-libtxc_dxtn at all (S3 Texture Compression
library). The website http://people.freedesktop.org/~cbrill/libtxc_dxtn/ says
it does not support NVidia cards anyway but it appears to get at least loaded
when installed
- I do not have libva and libvdpau: installed them from their respective git
versions, just in case
- I have not checked the difference between Mesa git that I am using and the
Mesa source provided by jobermayr, but the build options are very different, I
shall try building what I already have with those options, just in case
At the end of the whole story above, I finally managed to get the Nouveau
driver working with NoAccel disabled ! And it seems to be fast enough, surely
much faster than when NoAccel was enabled...
The logs are going to be attached in a minute.
It is now very important to understand what exactly was causing the problem,
amongst the few steps performed above. My bet is on Mesa build options from
openSUSE in the jobermayr tree, but I am not an expert and I might well be
wrong. Everything should be documented officially preferably by the experts and
developers rather than myself, so that it won't ever happen again to anyone
as
it is too annoying and time-wasting.

been there and I do not even know whether it is strictly necessary.
