Greg,

Thank you for the reply. I removed all the previous chimera installations
and ~/.chimera directory. Downloaded the latest 1.4 build and then
installated. Now when i start the chimera, i get the following error. I am
not sure if this is graphic card problem but i am attaching the glxinfo
output with the mail.

Traceback (most recent call last):
  File "/usr/local/chimera/share/__main__.py", line 65, in <module>
    value = chimeraInit.init(sys.argv)
  File "/usr/local/chimera/share/chimeraInit.py", line 374, in init
