Can't get past login screen in ubuntu 10.10


Hi, i'm running ubuntu maverick on a dell laptop and it was working flawlessly until the audio started stuttering so I looked up a possible cure for it. I came accross a post that said uninstalling pulseaudio would cure the problem - so i did through software centre. When I was uninstalling it there was configuration files to uninstall as well. When I shut down the laptop and tried to restart it, it goes to login screen with my name but when I click on login it goes back to the same screen. This is the first time this has happened and im not sure what I can do. Any help would be appreciated.

Michael.

What exactly did you remove to uninstall pulseaudio? For future reference, the only things you really need to uninstall to get rid of pulseaudio on Ubuntu are pulseaudio and
gstreamer0.10-pulseaudio.
Code:
sudo apt-get remove --purge pulseaudio gstreamer0.10-pulseaudio
Then run
Code:
gstreamer-properties
and set everything to alsa.

To reset everything to the way it was before you removed pulseaudio from the software center, try booting to recovery mode and then reinstall the ubuntu-desktop metapackage.
Code:
sudo apt-get install --reinstall ubuntu-desktop
Then reboot with
Code:
sudo reboot
and you should be back to where you were. Then uninstall pulseaudio the way I have stated above and you (hopefully!!) should be good.

Having the exact same problem, and this fix doesn't seem to work. Anything more specific? After logging in it is still returning to the login screen. Will not log in using root user or root password either. When I type sudo apt-get install --reinstall ubuntu-desktop into the root shell prompt, the screen fills with "could not resolve" and "failed to fetch" errors. The last line at the bottom says E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? apt-get update does not work either and for --fix missing, there is no command found. Any other fixes or ways to do this? Thank you, any help would be appreciated.

Hi Penceyarts, did you drop to shell with networking in recovery mode to try this?

Are you sure you have networking enabled when you boot to recovery mode? Are you able to ping google.com or yahoo.com from recovery mode? Are you able to run "sudo apt-get update" and have it update the repos without errors saying the repos are not found?
Verify that you have networking enabled, then try it again. The errors you are getting look like you could not connect to the Ubuntu repos.

Yes, I get the errors saying repos are not found. Sudo apt-get update gets to about 22 percent and then stops. Do I have to be connected directly to the internet through an ethernet cable? I don't have any LAN connected. So I guess my problem is with the connection now.

Hi Penceyarts, when you start in recovery mode with networking, does it start the DHCP Client and discover your connection? It should tell you if your connection is discovered, otherwise you may have to connect via ethernet.

it gives me the message 'No DHCPOFFERS received. No working leases in persistent database - sleeping. Then asks for my root password. So I'm assuming this means I need to connect via ethernet? How do I go about this? Thanks.

How do you normally connect to the internet? If you connect via wireless, then you will have to connect with ifconfig and iwconfig from recovery mode.

i usually use wireless, entered iwconfig and it doesn't connect to anything.


so, if reinstalling ubuntu-desktop will return my pulseaudio settings to normal, thus allowing me to log in, and I can't access the internet, how can I fix the ubuntu-desktop file with a flash drive or external hd?

Hi penceyarts, NO DHCPOFFERS received may mean that DHCP is not enabled on your router so the only way is connecting directly to the router via an ethernet cable or the way tommcd sugested. If you have access to your router from another pc then you may be able to turn on DHCP if you are the administrator.
