Hello,
An Aspeed VGA monitor, in my case AST 2400, after a suspend/resume
cycle suffers with a "No Signal" state. This is also true of a
IPMI/BMC remote console. To restore the "Signal" state requires
a reboot or the following workaround.
To restore the "Signal" state without rebooting issue the
following commands from a SSH session or serial console
after every suspend/resume cycle:
sudo modprobe -r ast
sudo modprobe ast
This a home media server which is updated infrequently, so
I am unable offer any guidance as to when this issue started
occurring.
Just to clarify, suspend/resume did restore the display in earlier versions?
Best regards
Thomas
