cannot log in after upgrade from 10.4 to 10.10 on amd64
After upgrading via the upgrade manager, I rebooted and found:
1. the default kernel wouldn't boot, just filled the screen with messages that I could not read - this was the case for a bug I reported on 10.04
2. the 1st kernel that would boot was the rt one.
3. this got me to the login screen but my password wouldn't work. I repeated it many times.
I now have no access to my system!
Please help me! I've been a long time supporter and debugger for Ubuntu, but now a feel abandoned!
