Gazpro6, updated this morning and now can't log in

[sviginak]

Type in my password and press enter, after a brief pause screen goes black, then appears to be blank and backlit?, then goes back to my login screen. It does not say my PW is wrong and I know it is right. After I try three times screen goes black.

Thinking it might be a security issue. I am at a B&B with no wifi password. Before I log in to computer I do not connect to wifi automatically, and when I try it says insufficient privileges. Usual suspect .Xauthority owner is not the problem.

sudo apt-get purge nvidia* worked, but in the meantime I had loaded Lubuntu which someone suggested earlier (but that didn't work). Now I would like to get rid of Lubuntu. Also, how do you mark a question as Solved?

[philinux]

Yes I had to purge nvidia too.
Just below the thread title click on thread tools to mark solved.

philinux - I still have the Lubuntu log in screen to get rid of. Also, I followed the link to remove old kernels, I am wondering if I should do that. I have a long list of stuff when I step through your six step process, below is after step 4;
