Public bug reported: Binary package hint: libgl1-mesa-glx
Since the update of "libgl1-mesa-glx" to version "6.5.2-3ubuntu1" (c. 2007-02-21) all opengl applications including glxgears fail on startup with the assertion error "c->xlib.lock failed". Eg: $ glxgears glxgears: xcb_xlib.c:50: xcb_xlib_unlock: Assertion `c->xlib.lock' failed. Aborted (core dumped) This patch fixes it: https://bugs.freedesktop.org/show_bug.cgi?id=8521 FWIW, this is the stack trace: #0 0xb7f7a410 in __kernel_vsyscall () #1 0xb7ddddf0 in raise () from /lib/tls/i686/cmov/libc.so.6 #2 0xb7ddf641 in abort () from /lib/tls/i686/cmov/libc.so.6 #3 0xb7dd743b in __assert_fail () from /lib/tls/i686/cmov/libc.so.6 #4 0xb7c67651 in xcb_xlib_unlock () from /usr/lib/libxcb-xlib.so.0 #5 0xb7d0abd4 in ??
