On my Tecra S1 laptop, running the experimental Xorg server with
vt console support, I noticed that Xorg loses access to the
/dev/srn device after switching from Xorg gui to a text console and back
to Xorg:
After Xorg is started I see:
# pfiles `pgrep Xorg` | grep srn
/devices/pseudo/srn at 0:srn
After switching to a text console and back to Xorg
the /dev/srn file isn't open any more:
# pfiles `pgrep Xorg` | grep srn
#
This is a problem if we now suspend the system, because
Xorg won't notice that the system is going to be suspended,
and doesn't save the state of the video hardware. After a
resume, the state of the gui video hardware is corrupted and
the laptop must be power cycled.
