[Triumf-linux-managers] Is your OPENGL broken?

[Frederick Jones]

Back in early October, x.org issued a faulty update
to the X11 packages that causes OPENGL applications
to fail, at least on three SL 4.x systems here at
TRIUMF.  The fault is apparently with the X server
itself (file "Xorg").  The fix I used was to back up to the
previous rpms:

xorg-x11-6.8.2-1.EL.69.i386.rpm
xorg-x11-Xdmx-... etc.
     -x11-Xnest-
     -x11-Xvfb-

I am not sure if this affects any SL 5.X or 6.x systems
but would be curious to find out.

If you have a desktop Linux machine, you can check it
by running "glxgears".  With the faulty X server it will
fail with an X protocol error.  If it works you will see
some spinning gears in a small window.
Also you can check the date on the file Xorg and see if
it was updated on around October 6 or so.

Cheers,
Fred
