Little black square at top-left of screen?

Hi all,

My BeagleBoard C4 is running Angstrom (X11/Enlightenment). Sometimes, there’s a little black square (estimated 10x10 pixels) at the top left of my screen (480x272 BeagleTouch). It disappears briefly (about 0.25 seconds) when the region is repainted, but then re-appears. I’ve found other reports on Google of black squares, but none that match the behaviour on my system.

What could be the cause?

I guess it is the cursor of your framebuffer console blinking...

remove the consolo on FB from your kernel config.
