Hallo,
ich habe hier einen Lenovo W541 (der letzte mit DVD-Laufwerk) mit NVIDIA-Grafik. Soweit ich weiß, handelt es sich um ein Dual-Grafik-System, wo man auch auf die eingebaute Intel-Grafik umschalten können müsste.
Nach mehrstündiger/tägiger Betriebszeit (in der Nacht durch "Bereitschaft" pausiert) zeigt sich immer mal wieder ein Flackern einzelner Fenster. Wenn ich z.B. in einem solchen Fenster scrolle, dauert es durchaus 1 Minute, bis sich der Fensterinhalt wieder beruhigt. Wechsle ich zu einem anderen Fenster und dann wieder zurück, beruhigt es sich auch, doch beim nächsten Scrollen kommt wieder der gleiche Effekt. Nach einer halben Stunde beruhigt sich das ganz oft auch wieder, und wenn nicht, hilft nur ein Neustart.
Wie kann ich statt der NVIDIA-Grafik die Intel-Grafik nutzen?
Auch weil ich die Leistung nicht brauche, und das Gerät dann weniger Strom aufnehmen würde.
