Black Screen With Mouse only

[UnKnOwN96]

Hello everybody,
This week i faced and still face a strange problem.
I have done three times clean install for this and still i can't find what causes it.
When i do my clean install and configure my installation, after reboot i can login.
I see the login splash and then, i see a black screen and the only thing i can do is open applications with ALT+F2 command and change TTYS to login as root and i can move my mouse pointer.
When i startx with root everything works awesome...
Probably i changed something i musn't...
Can the option "start everytime with new session" cause it, if yes how can i fix it and if not what can i do? Thanks in advance!

Three times this has happened? I'd check the disc. Boot from the CD and choose the "verify" (or something similar), option. Maybe you got a bad burn. It's the only thing I can think of, sorry.

Anyway thanks guys.

Did you do some configuring post-install that you think might be responsible? Or do you mean while installing? I can't imagine what you might have done during the installation that would cause this, unless it had to do with package installation.
