[Chimera-users] Error to run chimera remotely on a GPU computer from Mac computer

Dear listers, I ssh with "-Y" from my Mac desktop to a GPU computer and process my data there. Quite often I need to look at the 3D volumes with chimera. This had been working nicely for long time. But all suddenly it stopped working and game the error 3: X Error of failed request: GLXBadCurrentWindow Major opcode of failed request: 149 (GLX) Minor opcode of failed request: 5 (X_GLXMakeCurrent) Serial number of failed request: 1400 Current serial number in output stream: 1400 Did anyone encounter the same error? Any suggestions or tips to overcome this problem would be appreciated. Thanks, Zongli
