Problem:
On Linux (possibly also MacOS) with some card/driver combinations Ogre will hang up during initialisation of app window (displays the window and stops responding) Solution

I too had this issue when I was running Ogre samples with nvidia's beta driver. When I downgraded nvidia's driver to 100.14.19 this issue went away, even in FBO RTT mode.
Could you elaborate a bit? What does this option do, and what problem does it fix? Is there a link to something on the Ogre ste I could read about this? Ogre docs are usually not very good when it comes to string-based options -- it's hard to find out what such strings do.

It's due to buggy drivers. Apple's OpenGL implementation is known to have problems with FBO for example, and most OS X Ogre tutorials suggest using this option http://will.thimbleby.net/ogre/tutorial1.html http://wiki.python-ogre.org/index.php/O ... _the_Demos http://www.ogre3d.org/index.php?option= ... &Itemid=97 (see OSX-related notes)
Recently I've noticed that my own Ogre programs do not start anymore, and hang just after showing the window (same bug as discussed in the thread linked by loonycyborg). By pure luck I googled it, didn't notice that the solution wasn't refering to my problem but the OS X problem, and applied it ... with positive results. I guess nvidia broke their recent linux drivers in that respect.
