Surely you aren't saying the glx module is not loaded if you install the drivers from nvidia.com? It certainly does get loaded - here it is in Xorg.0.log for 260.19.44:
[ 52.970] (II) LoadModule: "glx" [ 52.994] (II) Loading /usr/lib/xorg/modules/extensions/libglx.so [ 53.006] (II) Module glx: vendor="NVIDIA Corporation" [ 53.006] compiled for 4.0.2, module version = 1.0.0 [ 53.006] Module class: X.Org Server Extension [ 53.006] (II) NVIDIA GLX Module 260.19.44 Sun Feb 27 22:56:46 PST 2011 [ 53.006] (II) Loading extension GLX Anyway, the glx issue is not really relevant. flash crashes in Natty using the standard Ubuntu nvidia-current driver. I only mentioned 260.19.44 because it is the last known working version. ** Changed in: nvidia-graphics-drivers (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/738600 Title: flash 10.2 plugin crashes when leaving full-screen with nvidia 270.30 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
