Public bug reported: This might be related to bug #525038. When starting up, the screen goes black (actually it looks like the backlight is not on) either instantly when plymouth starts or a few seconds after. The login screen appears, I typed my password and the screen is still black after logging in.
However, if I press F2 (decrease brightness) or F3 (increase brightness), not Fn + F2 or F3, then the display will come back on instantly. If I increase the brightness to its maximum setting and then decrease the brightness to the minimum setting using F2 & F3 respectively, I get the same effect when plymouth starts (no backlight). The brightness indicator that ubuntu shows when adjusting the brightness gives me only four levels going from 100% to 0%: 0 = 100% Brightness 1 = 60% Brightness 2 = 15% Brightness 3 = No backlight; and 3 levels when going from 0% to 100% 0 = 40% 1 = 80% 2 = 100% That's all the info I can give for now. If I wanted to get the Fn key working what package would I report that against?
