--- Comment #1 from Pascal Billery-Schneider sagittarius@laposte.net 2011-06-08 05:47:38 PDT --- I forgot to say that when I open the user preferences in Blender, Blender crashes with:
X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 155 (GLX) Minor opcode of failed request: 11 (X_GLXSwapBuffers) Serial number of failed request: 1007 Current serial number in output stream: 1008
So, the only way for the moment to be able to use Blender is to toggle composite and run de special script ./blender-softwaregl :(
