I have a Sony Vaio E series laptop. And I recently installed Ubuntu 12.10 on it. It was running all smooth without any problem, till I updated it (as we have to do after any normal installation of Ubuntu). But as I updated the system, it asked me to restart the system (which again is a normal thing), but after reboot, when the ubuntu 12.10 login screen came, it was all flickering. Nothing was properly visible, though I heard the sound, when the login screen come's. Interestingly when I took the mouse to the top of the screen, it was partly visible. Also when I closed the lid the system went to sleep, and after resuming the screen was all Ok again.

But still, can you help with this problem of flickering.

Thank You!

Thanks for the work around - although not perfect, at least I can log in now! –  Giles Smith Apr 29 '13 at 12:01

It's a kernel-related issue of kernel versions >=3.6.10 with your hardware. Please report that the bug affects also you on Launchpad: Launchpad bug 1123024
This will rise the priority of the bug.
