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.

KeyError: 'Pbuffer'

The Pbuffer code doesn't appear in chimera until after 1.3 in the 1.4 alpha releases (the daily builds).  So it looks like you started up a chimera daily build with the --debug-opengl option, saved a configuration, and then tried the 1.3 release.  The solution is to start the daily build with the --debug-opengl option, then revert to Factory Defaults and Save, so the 1.3 version sees the default setup (same as removing your ~/.chimera/gfxinfo.sav file).
