I have a problem that is more or less the same that this one:
I'm not sure of the exact sequence of events, but I install git-daemon on Ibex. I believe this installs runit (??).
When I boot, I get the Ubuntu splash screen come up, but about half way through it drops to the console with the message:
Loading the saved-state of the serial devices...
-runit: leave stage: /etc/runit/1
-runit: enter stage: /etc/runit/2
The computer just sits there without starting gdm. Virtual consoles still work, and I am able to startx from a different console. However, I don't have networking (ping doesn't connect to anything, for example), and Gnome complains about failing to initialise HAL.
I have now uninstalled runit, and can now get back to a useable system.
I have the same problem and for the same reason, but I can't uninstall runit because I can't log in with, for example, tty1 in tex-mode, because it says that my password is incorrect (and, believe me, I didn't forget my pass, and it hasn't non-ASCII characters, so I don't know what is the problem).
The only thing I can do is boot a live CD and do something from it, but the only solution I know is reinstall...
Any other solution?
Thanks a lot for your time!
