Hi everybody! I solved the problem by installing the nvidia non-free driver. The command "glxinfo | grep rendering" says "yes" and now wine don't make the X crash.
So I'm not really sure these crashes are the result of a bug. -- Crash when entering "glxinfo | grep rendering" https://launchpad.net/bugs/88511 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
