Ubuntu directly booting intu tty1

[ambdeep]

I was experimenting with new splash screens in the plymouth manager when my ubuntu stopped loading into the gnome desktop. Ive tried to search for some solutions over the internet but i cant seem to find any. and to top it all of, the server from which i used to get updates from seems to have stopped running.
i need help in changing my server via the terminal and to help restore my gdm. any help would be appreciated.

Since you have not received any other replies, here's what I would do. This probably isn't the best way, but it might work.

Open synaptic
Search for GDM
Mark for reinstallation
Apply

Follow the prompts.

Let me know if it works.
