nvidia driver ( GeForce FX 5500 gives 10fps)

[Michal Hajek <hajek1@karlov.mff.cuni.cz>]

Hello list :)

I have a problem with my Inno3d graphics card. 
I am using xfree package (4.3.0)
  -------------------
  In my /etc/X11/XF86Config-4 I have:
  Section "Device"
        Identifier  "Generic Video Card"
                Driver      "nvidia"
                #       Driver      "nv"
                #       NvAGP   1
                #       ChipSet     "GeForce FX 5500"
  EndSection
  --------------------------

  lsmod |grep nvidia gives:
  nvidia               4568124  12

  --------------------------
  glxinfo | grep direct gives:
  direct rendering: Yes

I have these packages installed:
dpkg -l nvidia* |grep ii
ii  nvidia-glx                      1.0.7174-3              NVIDIA
