I can't say I'm aware of this image, but the timing of it suggests to me it's a bug in ?dm (gdm3, kdm or whatever display manager you use). Probably an ACPI event happened which either GDM or X wasn't expecting. Do you, perhaps have one of these dual-mode graphics cards on that laptop? If so, the system probably switched to the high-power card at that point and either it wasn't initialised correctly or the low-power one was no longer available for X to display on.
