LTSP trava após login

[lucao1968]

Estou com um ltsp que trava após fazer login no usuário. olhando nos logs do sistema vi que acontece um erro com o login, mas não faço idéia de como corrigir isso segue abaixo os logs do terminal:

Também o meu lts.conf:

    X_COLOR_DEPTH=16
    LOCALDEV=True
    SOUND=True
    SYSLOG_HOST=server
    LDM_DIRECTX=True
    LDM_SYSLOG=True


Desde já, obrigado.

WARNING: App 'compiz.desktop' respawning too quickly

Desative o compiz.

[lucao1968]

WARNING: App 'compiz.desktop' respawning too quickly

Desative o compiz.

Obrigado pelo retorno zekkerj, mas meu problema era a opção ldm_directx=true no meu lts.conf habilitando esta opção a área de trabalho simplesmente não sobe, desativei isso e deu certo. qual seria a solução para isso visto que vou ter thin clients com pouco processamento?

[zekkerj]

O LTSP 5 subiu muito o requisito das estações. Eu consideraria trocar os equipamentos, se eles não atingem o requisito mínimo.

Fora isso, só resta desativar recursos que pesam sobre a estação, como o LDM_DIRECTX, o LDM_SYSLOG, SOUND, etc.

[lucao1968]

Ok, muito obrigado, desculpe a demora no feedback. mas parece que tudo está funcionando, exceto por um erro que acredito ser com driver de chipset ou vídeo nos thin clients.
Estarei usando uns thin clients com AMD GEODE e no iniciar aparece o seguinte erro na tela:
cs5535-mfd 0000:00:0f.0: MFD add devices failed: -16
e eu não encontro isso em lugar algum nos logs que olhei. teria algum outro lugar para olhar no servidor além do diretório /var/log?

E sobre remover o som e alguns outros recursos deu certo sim. melhora bastante!

[zekkerj]

Acredito que vc tenha que olhar no log da estação, não do servidor. E isso pode ser bem chatinho de configurar...

[lucao1968]

Estava pesquisando sobre isso agora... como fazer a estação gravar os logs no servidor, vou ver aqui o que consigo, acredito que este erro seja o causador da imagem meio borrada nos thins clients. mas a performance em abrir programas e o tempo de resposta está muito bom.
Por algum acaso você tem alguma idéia de como posso visualizar os logs dos thin clients?

EDIT
Consegui configurar os logs no servidor. O lugar onde consegui isso foi: http://ltsp4.2.revamp-it.ch/twiki/bin/view/ltsp/Syslog
agora tenho o log segue abaixo a parte do erro:
