"Desligar" me leva para cumprimentar agora?

ATUALIZAÇÃO - Remover meu dongle wifi USB parece curar o problema. O mesmo acontece com a desativação da rede (mas não a desativação do wifi sozinho). O que agora? ATUALIZAÇÃO 2 - O comando 'uptime' diz que há 2 usuários conectados. Isso certamente causará o comportamento que estou descrevendo. Vou vasculhar e ver se consigo determinar quem é o outro usuário. Deixa pra lá, isso foi devido apenas ao terminal que eu tinha aberto na área de trabalho.

Se eu entrar em qualquer conta, escolher 'desligar' ou reiniciar leva-me ao greeter. O mesmo acontece no próprio recepcionista - sou deixado lá. Nenhum outro usuário está logado.

Se eu não entrar em uma conta após a reinicialização, as opções de menu reiniciar e desligar no greeter funcionarão se eu as escolher imediatamente após o greeter aparecer. Veja um bootchart aqui: https://www.dropbox.com/s/ufb7s6ykvlbkjxj/jarlath-EP35-DS3-precise-20130116-3.png

Se eu esperar 5 segundos ou entrar em uma conta de usuário - eles não funcionarão. Eu testei isso várias vezes. Consulte um gráfico de inicialização (logado como usuário): https://www.dropbox.com/s/yx6jgoo2c7fy6pp/jarlath-EP35-DS3-precise-20130116-4.png

sudo -halt e sudo reboot funcionam como deveriam.

Eu produzi todos os processos de uma conta logada (ps -A) e os deixei aqui: www.pastebin.com/e3WHtHYm

Suponho que uma atualização, algo novo do centro de software (provavelmente porque eu não instalei nada no momento) ou um comando do terminal que eu emitei esteja causando isso. Aqui está o meu .bash_history desde antes do início do problema: pastebin.com/1DE5Tcd3

Meu kernel é 3.2.0-35, tentei também inicializar kernels antigos:

• 3.2.0-32, 31, 30, 29, 26, 25, 24, 23, 22 -> Sem diferença

Conforme as sugestões no bug https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/838792 , tentei:

• Ganhei meu /etc/init.d por serviços usando su e removeu 1 (ClamAV).
• Killed PulseAudio

Nenhum desses ajudou. Um pouco mais de contexto abaixo;

    jarlath@jarlath-EP35-DS3:~$ cat /etc/polkit-1/localauthority.conf.d/51-ubuntu-admin.conf 
[Configuration]
AdminIdentities=unix-group:sudo;unix-group:admin
jarlath@jarlath-EP35-DS3:~$ groups
jarlath adm cdrom sudo dip plugdev lpadmin sambashare vboxusers movies

No Logviewer, aqui está a saída gerada no momento em que tento desligar no menu do usuário:

Solução: Encontrei uma solução. Não o estou usando como resposta, pois não identifica a causa raiz, mas para outros que estão satisfeitos com apenas uma solução, devem tentar este conselho de grendndelman.net

Crie um arquivo chamado /etc/polkit-1/localauthority/50-local.d/usershutdown.pkla (o nome deve terminar em .pkla) e coloque o seguinte:

[Allow Shutdown]
Identity=unix-user:*
Action=org.freedesktop.consolekit.system.stop-multiple-users
ResultAny=yes
ResultInactive=yes
ResultActive=yes

[Allow Restart]
Identity=unix-user:*
Action=org.freedesktop.consolekit.system.restart-multiple-users
ResultAny=yes
ResultInactive=yes
ResultActive=yes

Se mais de uma pessoa estiver conectada, pressionar o botão de desligamento o levará ao greeter. Você ainda pode desligar a linha de comando com o comandosudo shutdown -h now

Tente sudo halt. Seria interessante descobrir se isso também o envia para o recepcionista.

Mesmo que esse não seja o seu problema, uma boa dica para quem vem com esse problema:

Eu pensei que estava tendo o mesmo problema:

Acontece que "shutdown" não funciona se outra sessão (SSH, ctrl-alt-f1, etc) estiver conectada.

No meu caso, a primeira vez que isso aconteceu, eu tive uma sessão SSH aberta para verificar a temperatura, mas a partir desse momento sempre havia algum tipo de sessão "agora verifique o que acontece nos logs", tornando o problema muito consistente.

Sair de todos os logins ssh / other fez o desligamento funcionar novamente.

tente desligar do terminal, pressione ctrl + F1 e execute sudo poweroff, ou apenas execute sudo poweroff do terminal, isso pode resolver temporariamente o problema

Você pode usar os comandos

Comercial

ou

W

para ver se alguém está logado de alguma forma.

Você poderia forçá-lo. Certifique-se de que os usuários anteriores desconectem, em vez de USUÁRIOS DO INTERRUPTOR.
