Bug Description
Binary package hint: gnome-power-manager
I discovered that is possible to lower the brightness on my laptop, an HP DV6245US, using the brightness down key, Fn+F7, until a point where the brightness is zero or off. After which pressing the brightness up key, Fn+F8, does not increase the brightness of the screen back thereby rendering my session unusable. I think the brightness level should stop before it turns off.
WORKAROUND:
It is possible to workaround this issue by switching to a different vty, Ctrl+Alt+F1, and then back to my desktop session by pressing Ctrl+Alt+F7. The brightness has then been restored to a normal level.
LATEST VERSION TESTED:
gnome-power-manager version 2.21.1-0ubuntu1
could you check if you see the same:
g_value_set_uint: assertion `G_VALUE_HOLDS_UINT (value)' failed
as in the log of the first comment in bug 136346 ?
