Public bug reported:
When starting Ubuntu normally, brightness button (Fn + F6/7) works
normally. Gnome shows the brightness notification. showkey shows
224/225. acpi-listen shows the event.
After suspending and resuming, brightness button does not work at all.
Gnome does not display the brightness notification. showkey does not
show anything. acpi-listen does not show anything either. However,
changing the brightness via the power settings / echo to
/sys/class/backlight/acpi-video0/brightness works.
