[Gmsh] Gmsh 2.8.3 shut down after 1sec.

[Norbert Guérard]

Hello,

Gmsh 2.8.3 is installed on my laptop with Ubuntu 12.04 LTS 32 bits OS.
When I double-clic on Gmsh icon, the Gmsh 2.8.3 window opens and 
suddenly closes after approximately 1 second.

When I try to open Gmsh 2.8.3 with the terminal, the following message 
appears:

norbert at norbert-laptop:~$ /opt/aster/public/gmsh-2.8.3-Linux/bin/gmsh
Error   : Unknown number option 'General.MessagePositionX'
Error   : Unknown number option 'General.MessagePositionY'

My graphic card is: [AMD/ATI] RV710/M92 [Mobility Radeon HD 
4530/4570/545v] [1002:9553]
and the corresponding driver is: "Pilote propriétaire ATI/AMD pour carte 
graphique FGLRX"

How can this problem be solved ?

Kind regards.
