This is 12.04 LTS on an AMD A8-3870 APU with Radeon(tm) HD Graphics.
Had 12.04 installed for a couple of weeks. Previously updated ~1 week ago.
Installed konqueror + available updates on 25/May apparently successfully.
On reboot, machine hangs in KDE splash screen, before login dialogue. No response to num lock, or other keys.
Can run recovery mode command prompt & networking.
Is there a way to find what updates were applied, and roll them back ?
Is there a way to stop the gui splash screen, and display text startup logging instead ?
