![Slackware 当前和 Radeon HD 6450:基于 OpenGL](https://linux22.com/image/86243/Slackware%20%E5%BD%93%E5%89%8D%E5%92%8C%20Radeon%20HD%206450%EF%BC%9A%E5%9F%BA%E4%BA%8E%20OpenGL.png)
我已经升级到 Slackware 当前版本(从 14.1 开始),除了 OpenGL 之外,一切都工作得很好。 Fglrx 15.302 无法针对正在运行的内核 (4.4.5) 进行编译,因此我决定坚持使用免费驱动程序。然而,尽管一切看起来都很好,但它根本不起作用:

Xorg.0.log 提到加载 GLX 扩展:

然而,任何 GL 应用程序都会因以下错误而崩溃:
glxgears
X Error of failed request: BadValue (integer parameter out of range for operation)
Major opcode of failed request: 154 (GLX)
Minor opcode of failed request: 3 (X_GLXCreateContext)
Value in failed request: 0x0
Serial number of failed request: 21
Current serial number in output stream: 23
glxinfo

任何想法?我错过了什么?

实际上,问题来自于 NVIDIA 安装程序的一个古老遗迹:
/usr/lib/libXvMCNVIDIA.so.96.43.11
删除所有孤立的 NVIDIA 文件解决了问题!
