I have Fedora 15 installed in my PC and I'm experimenting troubles while installing Surfer, a software for the visualization of algebraic surfaces.
The situation went like this:
- Downloaded the .deb package from the Surfer site.
- Downloaded alien and run it to conver the .deb package to an .rpm one.
- Tried to install it via rpm and got an error with dependencies: libtiff.so.4 missing.
- I had a look in /usr/lib and found libtiff.so.3.9.5. Reading some forums I found that a symbolic link
may work, but it didn't. So, I duplicated the libtiff.so.3.9.5 file and put the copy in /usr/lib under the name libtiff.so.4.
# ln -s /usr/lib/libtiff.so.3.9.5 /usr/lib/libtiff.so.4
- I run rpm like this
# rpm -ivv --nodeps surfer.rpm
Up to this moment everything was OK but after that rpm the situation got worse: the terminal crashed and the tasks bar(sorry if this is not its name) disappeared. I reboot the system and when it asked me to log in I could't do it. I mean, when I entered the user and the password it rejected the login as if I were trying an invalid user-password pair.
I tried rebooting and retrying login several times but I had the same problem over and over. As a consequence my system is now useless. I'm really confused because I have no idea of what's going on and I am new in Fedora and Linux world, so I don't know how to proceed.
Now, how do I recover my system? And, supposing that I can recover it, does anyone knows how should I overcome that trouble with libtiff.so.4?
I've made my best effort to adapt my post to the rules. If I falied, please tell me which mistakes did I make and I will correct them.
Thanks in advance and please forgive my English, I am not a native speaker.

I have tried a couple of things but nothing seems to work. I have a user lucas
in my system. When I try to log in via the CLI, I can do it as root but if I try to do it as lucas I just can't:
--/home/lucas: change directory failed: Permission denied
I'm a newbie so, what does this means? I think that this is saying the problem is not with passwords since I can log in as root with the password I used previously.
The problem is that when I try to log in graphic mode, I enter username and password and it takes me back to the log in screen. So, have I a problem with the graphic mode? If that is the case, how can I repair o reinstall it? In this direction I have to say that I can't get connected to Internet via the CLI so I can't use yum and stuff like that.
I am using Fedora 15 with LXDE.
