[color=990000]CentOS 5.7 has been installed on Dell precision T5500 workstation which has a ATI firepro 3D v4800 graphic card. [/color]
[color=000000]Before installing the graphic driver the command "glxgears" was working but display was improper (reddish blue shaded.. wavy screen).
After installation of ATI drivers (22.214.171.124 latest driver) the display was fine then, but the command "glxgears" is not working. It means the performance is low.[/color]
[color=CC0000]It says " X Error of failed request: BadRequest (invalid request code or no such operation)
Major opcode of failed request: 143 (GLX)
Minor opcode of failed request: 19 (X_GLXQueryServerString)
Serial number of failed request: 13
Current serial number in output stream: 13 "[/color]
For CAD simulation graphic card should be installed accurately, also "glxgears" command should work properly Anyone please help ......
