Hi Romand and J.P,

Since I updaged to Kubuntu 11.04 I too am getting intermittent X11
when opening up the viewer, the window resize when pressing 'f' has
also broken.  Frustratingly I can't reproduce it today so far...  When
I do get a crash on start up I get a warning from X11, and when I say
this previously I did a search on the web and found many dozens of
posts in various forums that discussed this same X11 error and later
versions of the Ubuntu family so it doesn't look to be an OSG specific
problem.

yes, I've also seen some posts on newer X11 version problems. What is weird is that changing OSG versions avoids the hanging.

I can get this to segfault every now and again:

osgviewer --window 0 0 800 600 cow.osg
Error: In Texture::Extensions::setupGLExtensions(..) OpenGL version test failed, requires valid graphics context.
Scaling image 'Images/reflect.rgb' from (128,128) to (0,0)
Segmentation fault

When it runs, I don't get the version test failed...

When I see the error again I'll post the error.

Robert.
