為了找出問題在那裡,找了一下系統中 OpenGL library 安裝在那裡:
krogh@ubuntu:/$ locate libGL
/usr/lib/libGL.la
/usr/lib/libGL.so
/usr/lib/libGL.so.1
/usr/lib/libGL.so.195.36.15
/usr/lib/libGLU.so.1
/usr/lib/libGLU.so.1.3.070701
/usr/lib/libGLcore.so.1
/usr/lib/libGLcore.so.195.36.15
/usr/lib/mesa/libGL.so.1
/usr/lib/mesa/libGL.so.1.2
/usr/lib/nvidia-173/libGL.so
/usr/lib/nvidia-173/libGL.so.1
/usr/lib/nvidia-173/libGL.so.173.14.22
/usr/lib/nvidia-173/libGLcore.so.1
/usr/lib/nvidia-173/libGLcore.so.173.14.22
/usr/lib/nvidia-current/libGL.so
/usr/lib/nvidia-current/libGL.so.1
/usr/lib/nvidia-current/libGL.so.195.36.15
/usr/lib/nvidia-current/libGLcore.so.1
/usr/lib/nvidia-current/libGLcore.so.195.36.15
想了一下想把 mesa 移除,沒想到會連帶一些 3D 軟體也移除,看來有可能是 Ubuntu 的問題.
