First of all, thanks for the reply. The results of your suggestion
are:<br>
<br>
comp@AbNormal:~/Downloads$ glxinfo | grep render<br>
direct rendering: Yes<br>
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer, <br>
GLX_MESA_multithread_makecurrent, GLX_MESA_query_renderer, <br>
OpenGL renderer string: Gallium 0.4 on NV46<br>
GL_NV_blend_square, GL_NV_conditional_render, GL_NV_depth_clamp,
<br>
GL_OES_depth_texture, GL_OES_element_index_uint,
GL_OES_fbo_render_mipmap, <br>
<br>
To me this, unfortunately, is a typical message - I have no idea as
to the meaning.<br>
<br>
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.<br>

<p class="MsoNormal"> Due to a rather catastrophic
failure I have just upgraded the OS from Debian v-7.2
to Debian v-8.4.0. I downloaded the DVD-1 and the
checksum was correct. When I burned it to a DVD here
were no problems. Nor, were there any problems with
the installation.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">However, several of the
applications that I use on rather a daily basis are
acting rather strangely. A case in point is Avogadro,
which happens to be a part of the distribution and
therefore I didn’t have to compile the source code.
It installed without any warnings or errors. When I
run the application the graphic window is corrupted!
This is also the case with another application, VMD,
that I downloaded and installed. Both application
worked without any problems in the previous Debian OS.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">There are other applications that I
run, both in gui’s and terminals that continue to run
flawlessly in the new OS.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Now, if that isn’t confusing
enough, I tried something else. I installed the Linux
VMWare Workstation 12 Player and installed the same
Debian 8.4.0 in that. And . . . the display
problem no longer exists!</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Obviously, I don’t want to have to
run the native Linux Distribution in an VM, but I
don’t have the faintest clue as to what is going on,
nor any inkling how to fix the problem.</p>
