Ubuntu 12.04 LTS loops the login screen unless you login as Guest
- by Mário Silva
I am running a VMWare Player with a Ubuntu 12.04 LTS Precise Pangloin as Guest on my Windows 7. Sometimes I get the shutdown blue screen error in Windows, this time it happened when I was running the Player. When I restarted everything Ubuntu gave the not so unfamiliar in this forum Login Loop in adminstrator login. I login and there's this black screen where I can only read: "piix4...smbus:0.0.0.07.3 Host Smbus controller not enabled" . When I go to the Prompt in root mode it fails to update and only upgraded, specially some plugins ( I think graphic plugins) which also appear in one an error message after quitting the prompt, but they´are successfully installed. They are not the error message. After that I have been working with the Fail/safe Mode recovery panel.
When I try to update via Root I get errors like this:
W:failed to fetch http://extras.ubuntu.com/ubuntu/dists/precise/release.gpg could not resolve 'extras/ubuntu.com
There are 8 more like this referring to areas like:
-archive/canonical.com
-ppa.Launchpad.net
-security.Ubuntu.com
-Us.archive.ubuntu.com - release.gpg
precise-updates/release.gpg
precise_backport/release.gpg
Final Message: some index files failed to download.....they have been ignored or old files are used.
The black screens most of the time pass by too fast for me to pick up any information. But in general I think I have done everything I was able to in the recovery panel including updating network and graphic packages and recovering filesystem packages and the basic stuff ( I am a beginner regarding Linux ) in the root prompt.
Now I am stuck in this screen with graphic options:
- Run in low-graphics mode just for one session
- Reconfigure Graphics
- Troubleshoot the error
- Exit to console login
I am trying to choose to reconfigure graphics but the mouse disappears in the virtual machine screen and sometimes when options change ity´s only the first and last option. ut this happens from the blue without messages. This particular option menu is in the regular GUI style against a black screen in Terminal style. Really strange.
Thanx in advance, all is welcome and appreciated.
