It seems that the fbdev went to sleep after some time. And the fbdev
is running on /dev/tty0. I typed the following to wake up the frame
buffer device.
echo -n -e "\\033[9;0]" >/dev/tty0

However, when I start X now, I get the following error:

# xinit

_XSERVTransSocketOpenCOTSServer: Unable to open socket for inet6
_XSERVTransOpen: transport open failed for inet6/10.0.2.15:0
_XSERVTransMakeAllCOTSServerListeners: failed to open listener for inet6

Please consult the The X.Org Foundation support

 for help.
Please also check the log file at "/var/log/Xorg.0.log" for additional

Any ideas anyone?
