Hi Francesco, The first thing to try is to reinstall your graphics driver -- Chimera works much better with the proprietary AMD and NVIDIA graphics drivers. If that doesn't work, send me email with the output from the CHIMERA/bin/linuxdist and the /usr/bin/glxinfo programs and we will be able to figure this out. -- Greg On 9/30/2012 1:50 AM, Francesco Pietra wrote:

does not start anymore:

Error inizializing OpenGl. Couldn't configure togl widget.

Before I go messing the system, may be I can get advice on where to put the hands. libgotl is not installed, but the same occurs with my GTX-680 amd64 system, where chimera works fine.

Thanks
