I think that what you are saying is also (or something near) the reason
why the framebuffer crashes after a vterm exchange from X .
Is it possible that X is not signalled to release its resources and go to=
=20
sleep ?
The few times that i am able to exchange vterms, X is completely killed=20
(also its child tasks) by the system and the Xdm task that remains alive
is not able to re-open another X task.=20
I can test it, could you suggest me where to put the hands :-) ?

Post Scriptum.
In my last mail i forgotten to say that after the migration of my Linux=20
partitions from IDE to SCSI hdisks, a strange bug seems disappeared:
Sometimes, when connected to internet and using X, something
hanged the X task or the whole machine. Now seems solved...
(I cross my fingers... :-) ).
