Very good, Mark. That is a perfect solution--thank you,MU wrote:libgl.so is included in the archives in /usr/local/graficsdrivers.
Some drivers need it in /usr/X11R7/lib.
If you comment that line, a wrong libgl.so is used, what can cause crashes.
Instead you should do something like:
rm -f /usr/lib/libGL.*
ln -s /usr/X11R7/lib/libGL.so /usr/lib/
ln -s /usr/X11R7/lib/libGL.so.1 /usr/lib/
So using this symlink, you have the correct version in both folders.
