The warning message suggests that your "patch" broke accelerated X11.
To check,
$ xdpyinfo
and look for GLX
if it is not there your X11 can no longer make OpenGL
drawing-areas/windows.
That needs to be fixed obviously.

The patch is called a security patch to the OS by our IT dept. I believe
it made changes to the X11 system. While I am waiting for response from
our IT dept., I am hoping to find some specific area to look into.

Re: Coot window problem after patch

Hi,
We are having a problem with the coot window in our Linux machines after
a patch. The error message reads like
(coot-real:8985): GtkGLExt-WARNING **: cannot create GdkGLContext
(coot-real:8985): GdkGLExt-CRITICAL **:
gdk_gl_window_impl_x11_make_context_current: assertion
`GDK_IS_GL_CONTEXT_IMPL_X11 (glcontext)' failed
The OS is RHEL 5 (x86_64). I wonder if anyone has suggestions on where
to look for the problem.
Thanks,
Yong
it may help if you tell us what you mean with "after a patch".
