[colug-432] A Perplexing Problem

[Stephen P. Molnar]

First of all, thanks for the reply.  The results of your suggestion are:

comp at AbNormal:~/Downloads$ glxinfo | grep render
direct rendering: Yes
     GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
     GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer,
OpenGL renderer string: Gallium 0.4 on NV46
     GL_NV_blend_square, GL_NV_conditional_render, GL_NV_depth_clamp,
     GL_OES_depth_texture, GL_OES_element_index_uint, 
GL_OES_fbo_render_mipmap,

To me this, unfortunately, is a typical message - I have no idea as to 
the meaning.

The catastrophe to which I made mention was two fold; (1)  the CPU fan 
failed which resulted in overheating and (2) the video card failed and 
was replaced.  Unfortunately, the repir tech didn't give me an 
information about the care, but I assume he installed the approp;riate 
drivers.  I'll check into that.
