Just tried xubuntu 13.10 on the same laptop, keeping 12.10 on its partition to
boot on one or another as will.
Xubuntu 13.10 is freshly installed, not much customized but updates applied and
rebooted.
Kernel is 3.11.0-12-generic .
lsb_release -rd
Description: Ubuntu 13.10
Release: 13.10
On xubuntu 13.10, things that worked still work (hotkeys, etc), things
that were unusual did as on 12.10 (e.g. Fn-F7). The good news is that
Fn-F5 and Fn-F6 changed.
The following misbehavior that were true on 12.10 have changed:
> * pressing Fn-F5 and Fn-F6 *does not* show on-screen notification ->
minor
Now there *is* an on-screen notification.
> Fn-F5 (brightness down) cause no event seen by xev
Now it causes this:
MappingNotify event, serial 37, synthetic NO, window 0x0,
request MappingKeyboard, first_keycode 8, count 248
FocusOut event, serial 37, synthetic NO, window 0x3400001,
mode NotifyGrab, detail NotifyAncestor
FocusOut event, serial 37, synthetic NO, window 0x3400001,
mode NotifyUngrab, detail NotifyPointer
FocusIn event, serial 37, synthetic NO, window 0x3400001,
mode NotifyUngrab, detail NotifyAncestor
KeymapNotify event, serial 37, synthetic NO, window 0x0,
keys: 74 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
RRNotify event, serial 38, synthetic NO, window 0x3400001,
subtype XRROutputPropertyChangeNotifyEvent
output LVDS1, property Backlight, timestamp 848645, state NewValue
> Fn-F6 (brightness up) cause no event seen by xev
Now it causes this:
FocusOut event, serial 41, synthetic NO, window 0x3400001,
mode NotifyGrab, detail NotifyAncestor
FocusOut event, serial 41, synthetic NO, window 0x3400001,
mode NotifyUngrab, detail NotifyPointer
FocusIn event, serial 41, synthetic NO, window 0x3400001,
mode NotifyUngrab, detail NotifyAncestor
KeymapNotify event, serial 41, synthetic NO, window 0x0,
keys: 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
RRNotify event, serial 41, synthetic NO, window 0x3400001,
subtype XRROutputPropertyChangeNotifyEvent
output LVDS1, property Backlight, timestamp 853274, state NewValue
Just in case this difference in behavior could be due to a different set of
installed packages, here is the an output on the working Xubuntu 13.10:
LC_ALL=C dpkg -l '*power*'

Here is the same output on the failing Ubuntu 12.10:
LC_ALL=C dpkg -l '*power*'

As you can see, the only difference is gnome-power-manager installed.
