[ATrpms-users] nvidia-graphics7185-1.0_7185-74.3.fc7 should have .so instead of .o?

Not in the legacy 7185 though?

http://http.download.nvidia.com/XFree86/Linux-x86/1.0-8178/README/appendix-c.html 
says "The nvidia_drv.so driver is compatible with Xorg 6.8 and greater 
with "dlloader" support."

http://www.warrenfalk.com/blog/2006/04/05/ati-radeon-x850-on-vs-linux/#comment-23 
says (not about MY problem) "The problem is almost certainly an X11R7 
problem due to the fact that they only support dlloader whereas they 
used to support elfloader also."

I believe Fedora 7 is using X11R7?  If so, it seems like I NEED a 
".so".

I also see that 
http://rpm.pbone.net/index.php3/stat/4/idpl/4151294/com/xorg-x11-drv-nvidia-legacy-1.0.7185-1.lvn5.i386.rpm.html 
contains a "nvidia_drv.so" instead of ".o".

The kernel module does load okay.  Not sure how to check the arch via 
'rpm', but 'file' seems to indicate at least that the "nv_drv.so" that 
works has the same arch as the "nvidia_drv.so" that does not:

# file /usr/lib/xorg/modules/drivers/nvidia-1.0-7185_drv.o
/usr/lib/xorg/modules/drivers/nvidia-1.0-7185_drv.o: ELF 32-bit LSB 
relocatable, Intel 80386, version 1 (SYSV), not stripped
# file /usr/lib/xorg/modules/drivers/nv_drv.so
/usr/lib/xorg/modules/drivers/nv_drv.so: ELF 32-bit LSB shared object, 
Intel 80386, version 1 (SYSV), stripped

I don't have any others, this is a clean install - I only just started 
with Fedora :)

I did have some problems with udev and SELinux - I got lots of 
boot-time errors regarding the creation of nvidia0, nvidia1, etc., but 
I resolved those using 'audit2allow'.

Thanks in advance,
David
