Comment 13 for bug 81339

Same problem as in the previous two comments. Brightness applet still works to adjust brightness (as it did in 8.04) but now (after installing 8.10) does not show the brightness percentage when hovered over - instead displaying "cannot get laptop panel brightness".

(Straight after login, the applet shows the correct brightness of 100% but as soon as the slider is adjusted the problem presents itself.)

This does not seem to be a duplicate of #43572. The problem did not exist until 8.10 was installed and also, in this case, is affecting a Sony VGN-FS315M laptop not a Dell.
