Were you running MC in TDE? Have you set its screen power save to maximum 120
minutes (as I do)?

Have you tried booting with consoleblank=0 on kernel cmdline?

Have you tried anything like xorg.conf for dpms? e.g.


	Section "Monitor"
	    Identifier "DefaultMonitor"
		Option	"DPMS"	"off"

Have you tried setting BIOS suspend mode to S1 instead of (typical default) S3?
