What about libnvidia-wfb.so ?

[kwizart]

I've notice a new file appear in the 97xx series (that enable support for G80)
Does this file is usefull for chipset older than G80?
What is the aim of this file?
This file seems to have an SONAME but is it usefull for devel purpose?

Bonnes fètes de fin d'année!
happy new year!

The new library is a libwfb.so replacement for GeForce 8800 GPUs; it is only used by the X driver.

[kwizart]

Do this file can be placed elsewhere for exemple /usr/lib/xorg/modules/extension/nvidia assuming that it will be found by it SONAME?

You mean the X driver use it so it is not necessary to make some special tweak in the xorg.conf? And also that the library will be use if the driver detect the necessary hardware ?

[AaronP]

The file can be placed anywhere, as long as the X server can find it (either through the ModulePath directive or via a symlink). The SONAME is not used. The driver will automatically try to load a module called "wfb" (i.e., libwfb.so), which is installed as a symlink to libnvidia-wfb.so.x.y.z if no libwfb.so existed at install time.

The driver will always try to load it, but it will only be required if a GeForce 8800 or higher is detected.

I'm using the atrpms package for nvidia 9764 and I'm getting errors finding wfb but I have a 6200 TC card, so I assume this is not a problem, but should this library still exist? ie is this a packaging problem or a configuration problem for me?

(II) Loading sub module "wfb"
(II) LoadModule: "wfb"
(WW) Warning, couldn't open module wfb
(II) UnloadModule: "wfb"
(EE) Failed to load module "wfb" (module does not exist, 0)

It should still be present, but since it's a new file, some third-party packages do not include it, yet.

Hi,

this has been filed at ATrpms as http://bugzilla.atrpms.net/show_bug.cgi?id=1087

The issue is more with 3rd party packages trying to emulate the work of nvidia-installer and therefore missing some new development. I'm currently ripping out the Makefile based builds in order to use nvidia-installer calls (and therefore "never" miss any such changes again).

Sorry for the breakage, the fix will be available soon.

[mtrax]

no problems thanks anyway..

[thimm]

OK, I updated the packages on ATrpms for FC5+6+7 including cubbi's suspend2 series and RHEL3+4. Please give them a try, I don't have any 8800 to try it with.

Depending where the libnvidia-wfb.so.x.y.z is installed (by third part repositories) it has to be symlink. It seems to work fine like this:

ln -s libnvidia-wfb.so.x.y.z usr/lib/xorg/modules/extension/nvidia/libwfb.so

libwfb.so do not seems to exist on Fedora Core 6, so there is no replacement tweak at this time.

Since this version drop support of NV30 and older we need to do another "legacy" version for aiglx with NV30 and older.
The usual legacy version is still usefull for DGA server and is used by some (fews) app like tv software (xdtv..., mayve xawtv?)
