New subject: Continuation of my futile attempts at configuring ATI videocard driver for Freesurfer=)

12 Jan 2011


      Dear Freesurfers,
I keep fighting with my 64bit-CentOS in order to configure my videocard 
(ATI Radeon Sapphire HD 5750) for FS. At last I got rid of "segfault 
error". And now there is another error (after tkmedit command):
=============================================================
X Error of failed request:  BadRequest (invalid request code or no such 
operation)
  Major opcode of failed request:  143 (GLX)
  Minor opcode of failed request:  19 (X_GLXQueryServerString)
  Serial number of failed request:  15
  Current serial number in output stream:  15
=============================================================
I assume there is a problem with OpenGL... I have searched in archives, 
googled but unfortunately haven't found useful information on this 
topic. Do you have any idea how to solve this problem?
My "xorg.conf"-file includes following:
