I have dual boot config with kubuntu 12.04 and Windows7. My problem started this morning when I tried to boot kubuntu. Everything worked fine a couple of days ago and I have not done any mayor system configurations since then.
Choosing kubuntu options from grub gives me this screen
A couple of minutes later this screen is shown
And then it gets stuck. Have been waiting for ~5mins without anything happening.
I have tried running fsck from recovery menu without any errors. I have also tried booting in failsafex mode which gives me "Fatal server error: no screens found". apt-get update gives me "Duplicate sources.list entry". I have also tried fixing broken packages from recovery menu.
What should I do next?
