Comment 3 for bug 1386005

I have reproduced this problem in local testing, but it was only by accident in a configuration that is not expected to happen on a real system (namely, by manually removing vt.handoff=7 from the kernel command line).

Please run 'apport-collect 1386005' from the affected system, and attach your /etc/default/grub.

It's quite possible that this is a problem specific to your use of uvesafb. This is not a supported or tested configuration in Ubuntu; indeed, nvidia upstream insists that use of framebuffer kernel drivers with their binary driver is unstable and leads to video corruption. If this is only reproducible with uvesafb, it will be a low priority to fix.
