RE: How to recover from blank screen on sparc64
Not seeing any error messages on the serial console.
I'm seeing a two-line error message flashing briefly on the blank screen.
Something about lp0 using parport0 - interrupt driven
Here is something that appears in Xorg.0.log:

Are you seeing any error messages on the serial console?
Have you checked /var/log/Xorg.0.log?

There seems to be related discussion [1].
