"Check disk for defects" shows black screen

Bug Description

I made a persistent live USB key from http://cdimage.ubuntu.com/kubuntu/daily-live/20100416/lucid-desktop-amd64.iso (md5sum 3457aff4863972bbb38806e68cd30a77), booted my computer from it, and selected "Check disk for defects". The screen went black and nothing else happened AFAICT.

The root cause is probably the video problem discussed in bug #557744.

However, "Check disk for defects" isn't optimally useful if it is affected by video problems. Shouldn't it run in some incredibly safe video mode?

On another of my computers which is affected by bug 564471, the "check disks" progress screen suffers from garbled colors, to the point that the final message displayed after the check is unreadable.

This affects me on my desktop computer since quite some time already (at least since 12.04, and now happening on 13.04 again). Might have something to do with the fact that I use a multi-monitor configuration, or that I use the "official"/proprietory driver from AMD for my Radeon?

 For me, at each 30th reboot or so, the screen stays completely blannk, but pressing "C" (as I remember from other machines or older versions) will get me to the desktop - so I suppose a disk check was running while there was this blank screen...
