刚在RH9下装了个游戏quake4,但运行提示如下错误:
--------------- R_InitOpenGL ----------------
Initializing SDL subsystem
Loading GL driver 'libGL.so.1' through SDL
TODO: Sys_SetClipboardData
********************
ERROR: SDL_SetVideoMode failed: Couldn't find matching GLX visual
********************
--------------- BSE Shutdown ----------------
---------------------------------------------
WARNING: rvServerScanGUI::Clear() - invalid scanGUI

idRenderSystem::Shutdown()
Sys_Error: SDL_SetVideoMode failed: Couldn't find matching GLX visual


请问是怎么回事,该怎么解决啊?
请各位大虾赐教,谢谢
