I doubt that the preferences file has anything to do with this. Please file a bug report with chimera's Help / Report a Bug dialog so I'll have enough information about your system to make a good suggestion on how to debug this program. And please include the output of the glxinfo program that you run after chimera starts failing. -- Greg On 10/28/2010 01:14 PM, Harry Kao wrote:

On a linux workstation, a particular user is receiving the following error message when starting up Chimera:

Display misconfiguration. Please increase the color quality (24 bit color or greater), update your display (graphics) driver, and/or upgrade your graphics card. Also see chimera installation instructions.

This error message happened after a previous Chimera session crashed. The user had about 10 models open. The display setting is already at 24bit, and the workstation has the correct Nvidia driver.

Here is what we tried: 1. On the same workstation, under a different user account, Chimera starts up fine, no error message.

2. I created a new empty user directory, Chimera starts up fine the first time and the user can re-open models he was working on. However, the error message returns in the next Chimera session.

Based on the observation, I am assuming there is a user-specific configuration/preference file that Chimera reads when starting up. Perhaps in that file, some display parameter is being corrupted? If so, where or how can I find and fix or delete such files?

Thank you.
