We've been having weird problems with screen blanking in Solaris 10
on SPARC (no idea about X64 -- we don't use it). On a Sun Blade 100
that we've been using for testing, the built-in M64 framebuffer will
blank properly - sometimes - but will then unblank after 30 minutes
of inactivity.

Something even more annoying happens if we run with two framebuffers
and with ximerama enabled -- if you are logged in it will only unblank
the primary framebuffer. The only way that we've been able to unblank
the secondary framebuffer is to log out.

I've seen some discussion about this problem in comp.unix.solaris,
but there never seemed to be a solution.

Please remove the "nospam" from my address if responding via email.
