Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

Updated this weekend from 10.04 to 11.10 and now when I boot, I get the standard "Mythbuntu" boot screen then sections of text, then blank screen, then text, then blank scree, etc until I finally just get a black screen.

I am Running an ATI video card HDMI out to TV. I have tried other TV's, VGA Monitors, etc, all yield the same result.

How do I at least stop the boot process from loading the GUI and dumping me into CLI so I can start to fix this thing?

Thanks.

Besides doing what has been suggested to you, remember to uninstall the Graphics drivers, FGLRX if you have them installed as it can break when doing an upgrade. –  Uri Herrera Feb 21 '12 at 2:24
    
You mean you upgraded to 10.10, then 11.04, then 11.10 right? –  psusi Feb 21 '12 at 3:31

There has been some reports of the lightdm transition not working properly for some people. Check your logs in /var/log/lightdm/

If there are errors about a unity-greeter, please remove the package 'unity-greeter' and make sure 'mythbuntu-lightdm-theme' is installed.

You may have to reconfigure automatic login too (there is no longer a GUI tool).

In summary:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get remove unity-greeter
sudo apt-get install lightdm
cd /etc/lightdm/
sudo mv lightdm.conf lightdm.conf.old
sudo nano lightdm.conf

In the lightdm.conf file put the following:

[SeatDefaults]
autologin-guest=false
autologin-user=<<your mythtv user ID, ie: superm1 or whatever>>
autologin-user-timeout=0
autologin-session=lightdm-autologin
user-session=mythbuntu
allow-guest=false

Guys, thanks for the info! I did sudo apt-get remove fglrx, then followed the instructions for lightdm, reboot, still just a black screen, so I did a sudo apt-get install fglrx, reboot and now it works!! Yay... –  tbackus Feb 22 '12 at 0:10
