Comment 6 for bug 1042359

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*'

ii xfce4-power-manager-dat 1.2.0-2ubuntu1 all power manager for Xfce desktop, arch-indep files
un xfce4-power-manager-plu <none> (no description available)

Here is the same output on the failing Ubuntu 12.10:

LC_ALL=C dpkg -l '*power*'
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend

ii xfce4-power-manager-dat 1.2.0-1ubuntu1.1 all power manager for Xfce desktop, arch-indep files
un xfce4-power-manager-plu <none> (no description available)

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