Recently I installed Ubuntu 9.10.. I was trying to install some java runtime, and after the installation was done, I did a reboot.. Ubuntu booted normally but the normal Ubuntu 9.10 login screen is gone..now I have an old Debian style login screen asking for username.. the screen is similar to this one here, but with a black background:
I thought that it was something with usplash, but in the end I realised that it's something with GDM.. on the Debian login screen, if I press CTRL + ALT + F1, I can get to the terminal and from there I login normally with my username and pass..
After I'm doing "sudo gdm" and it's login automatically to my gnome desktop..after that if I logout, the normal Ubuntu 9.10 login screen is back..
After some rebooting, the old style Debian login screen is back again.
Any ideas what I should do, or what configuration I should change?
