dlopen: /usr/lib/xorg/modules/extensions//libglx.so: undefined symbol: _nv000028gl

I messed up - I used to be using the stable 185.18.36 from Ubuntu 9.10, then I removed all nvidia*185* packages and installed 190.40 from here.

Then I did not remove the 190.40 but simply reinstalled the 185.18.36 from Ubuntu's Hardware Manager and now GLX does not start:

Xorg.log:

(II) LoadModule: "glx"
(II) Loading /usr/lib/xorg/modules/extensions//libglx.so
dlopen: /usr/lib/xorg/modules/extensions//libglx.so: undefined symbol: _nv000028gl
(EE) Failed to load /usr/lib/xorg/modules/extensions//libglx.so
(II) UnloadModule: "glx"
(EE) Failed to load module "glx" (loader failed, 7)

Looks to me that's because I did not properly remove the 190.40. Anyone here knows how to fix that?

Yes. remove 190.40 with the nvidia installer and the --uninstall option, then re-install ubuntu packages.

If you have good reasons to install a driver by hand in ubuntu, please read the documentation provided in the sticky thread here _and_ the documentation provided by ubuntu.
