I am running Ubuntu Studio 12.04 64-bit version.
I have OpenGL and libGL stuff installed, but recently things that
require it no longer run and I get an error message when trying to run
from the command line like this:
cairo-dock: error while loading shared libraries: libGL.so.1: cannot
open shared object file: No such file or directory
I have libgl1-mesa-glx installed, which provides libGL.so.1
I have Codeweavers Crossover 12.0 installed as well, and this has a
diagnostics program cxdiag which gives the following output:
~$ /opt/cxoffice/bin/cxdiag

OpenGL and DirectX applications, including most games, will likely
not work. Other applications should be unaffected."
I already installed the 32-bit libraries required by Crossover. Although
if it still needs the ones listed above, then how can I install those?
i.e. instead of the 64-bit versions, what command do use to install a
32-bit version? I tried sudo apt-get install libgl1-mesa-glx:386 and
similar but nothing got installed as it could not find the package.
Things like Cairo Dock which was the first thing I noticed had failed to
run yesterday needs OpenGL libraries and so will not run, although I do
not know if it is 32- or 64-bit.
Before that everything worked fine. So I do not know what happened to
break the system and OpenGL.
The only thing I can think of is I had a small problem with Crossover
running Photoshop, and I had to install the libjpeg (or similar)
library, 32-bit, to get that working. And I updated Crossover from 11.3
to 12.0.
Any ideas on how to get OpenGL working again?
