I installed compiz a while ago and at some point to decided to remove it. I did that through Ubuntu Software Center, rebooted the system and wasn't able to "login" since it said something like "Can't start Ubuntu session".
How do I repair the system or make it work somehow?
P.S. I have a bootable usb flash with Ubuntu 13.04. And I can to connect to the Internet through Wifi, but I need:
Choose a network manually and enter the password
(It might depends on some parameters, but anyway) Open any url address so that that wifi spot redirects me to its
default page where I have to press a button like "Enter", after that
it redirects me to its default page again and eventually I'll be able
to use the Internet normally.
Will it help me?
