Operating Systems Linux Ubuntu Blank screen after upgrade from 11.10 to 12.04! Post 302741291 by yifangt on Saturday 8th of December 2012 12:48:35 AM

Thanks GTrip!

I can't remember exactly what it was, but it did not bring the GUI back and I switched to look for other solutions.

I tried
Code:
apt-get -f install;

and long list of errors, that's why I was asking to how to save the STDOUT to files for diagnosis. I noticed many of the errors are libqt4 related, several mysql and perl related. I can't copy the error logs from the crashed machine, which is another frustrating thing! And my colleague recommend a new fresh installation from the beginning, which I do not want to do as I was not expecting this breakdown and no backup was done before I start (I know this is stupid, but I tried another upgrade without any problem, so I had thought it should be fine!)

Anyway, it seems to me the upgrade was complete except the GUI is not back. Do you have other clues? I appreciate if you could walk me thru this. Thanks a lot!
