[solved] ksmserver can't start - NVIDIA driver problem

[Chopstick]

Hi all,
I upgraded from jaunty to lucid (64bis) and I have an NVIDIA video card.
upon rebooting I got to the login screen, but when I tried to log in, KDe aborted after a few seconds and said "can't start ksmserver - check your installation" (or something to that effect), and threw me back to the login screen.

It turns out this is a problem with the proprietary NVIDIA driver; you just have to delete some old libs:

cd /usr/lib/
sudo rm libGL.*

(be careful with the dot '.'! or you delete more than you should.)
I found the solution here:

It worked for me and I thought I might save others some time by posting it here (it took me some time to find this anyway...)

Otherwise the upgrade went well.

I had the same issue. Turns out that the problem is not with nvidia driver (current). The libGL files were probably left by an old (nvidia?) driver. Hope that others will find this post sooner than I. It took me all day to figure it out...
