Hibernation
 

New Installation of Suse 9.2 Professional on IBM ThinkCentre 8084.
Initially system works fine, then after a while, screen goes black with VDU (Iiyama Vision Master 17) showing "No Signal". Move mouse and screen repaints but time has stopped. Pass mouse over time and time changes but not ticks! Screen soon goes black again. Onwards system becomes very slow and pretty well unworkable.
Any assistance would be appreciated.
