Hello; Today I compiled 2.6.25-rc3 to test it out, and noticed fglrx is
giving me an error:

I dont use 3D, but if I did how would fix this problem, so I can enjoy
fglrx?

Hello; No I was unaware of the radeonhd, thanks for the advice

Hello; I'm trying to compile fglrx and seem to be reciving a posix security
error. Does anybody know what I could put into firegl_public.c to make this
work. The module compiles if you take out cap_t function (1889:
firegl_public.c), but having security features taken out, makes me sketchy.
the error is below:

/lib/modules/fglrx/build_mod/2.6.x/firegl_public.c:1889: error: implicit
declaration of function 'cap_t'
/lib/modules/fglrx/build_mod/2.6.x/firegl_public.c: In function
'KCL_PosixSecurityCapSetEffectiveVector':


  return cap_t(current->cap_effective);      <---how would I modify this in
firegl_public.c to make the module correctly?

Hello; I was fortunate enough to have bob knight give me some diffs to
get fglrx working, below you will find them:

Here's the diffs I used to get it working in firegl_public.c:

PAGE_KERNEL_NOCACHE);

Use at your own risk...

Cheers,
Bob


Bob probably didn't have difficulty with cap_t, but I did, I ended up
using 2.6.17 capability.h for the module to compile.

Have you tried the free software radeonhd driver [1]?
It should be faster than the fglrx driver without the kernel module.
