Hallo,
ich bin heute auf Ubuntu Bug 818830 gestoßen. Kann einer der anwesenden X220/T420(s)-Besitzer das Problem mit RC6 bestätigen?

* Activating rc6 results in render glitches
die Version kenne ich gar nicht. Woher hast Du die?tlp (3.4.1)
leider kann TLP, wie wir in diesem Test feststellen mußten, RC6 und FBC nicht wirksam schalten obwohl es im Sysfs so aussieht. Genauso wenig kann es die damit verbunden Treiberfehler "wegzaubern". Den Lehrgang wollte ich nächstes Jahr besuchen ...Bootparameter entschärfen
