Nice script. Much better than nvchooser.
It tells me that libglx.so is missing.
also X doesn't start now but it did last night and I haven't updated a thing since then (been on Widoze).
Looks like a reinstall to me. the Nvidia doc says that the tarball method removes the previous drivers when the ;make install' is run so I will stick with that.
I have no idea if that does a clean-up as well but we'll see.
Thank Heavens for dual boot ! (and good Fora !!).
