Description Hongna Xu 2012-01-08 19:02:02 UTC 
The new location is: /usr/lib/x86_64-linux-gnu/libGL.so for X86-64 machine.
The log followed:
===========================================================
WARNING: distccd not present, no distcc support loaded.
WARNING: nVidia proprietary OpenGL libraries detected.
nVidia's OpenGL libraries are known to have compatibility issues with qemu,
resulting in a segfault. Please uninstall these drivers or ensure the mesa libGL
libraries precede nvidia's via LD_PRELOAD(Already do it on Ubuntu).
Skip nVidia's libGL on Ubuntu!

Comment 1 Jiajun Xu 2012-01-08 23:54:07 UTC 
Without libGL.so, with Hongna's Ubuntu 11.10 system, qemu could start up but if we run glxgear command, qemu will segfault.
Comment 2 Saul Wold 2012-01-10 08:50:02 UTC 
It seems there is a check in runqemu for /usr/lib/*-linux-gnu/libGL.so, but in the runqemu-internal it hard code adds /usr/lib/libGL.so to the GL_LD_PRELOAD list. We should be passing or re-check where the library resides to runqemu-internal.
Comment 4 Hongna Xu 2012-03-09 06:44:57 UTC 
Verify the bug as fixed with poky/1.2_M3 branch, commit 320558f494c618f53e0c773db3ea0109476e8359.
