Hi I used to be able to run chimera remotely from a machine with an X- windows server (the one that comes with Cygwin in this case). But now I get the following error: Xlib: extension "NV-GLX" missing on display "localhost:10.0". X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 148 (GLX) Minor opcode of failed request: 181 () Serial number of failed request: 12779 Current serial number in output stream: 12784 I t does work fine if run directly from the computer where chimera is installed. Any idea what the problem could be? Thanks Server computer: Chimera v 1.5 (similar problem with 1.6) OS: Linux OpenSuse 11.3 64b Client computer: OS: Windows 7 64. Graphics: ATI Radeon HD 5450
