Bumblebee segfault em drivers nvidia

Question

Eu recentemente tentei usar meu laptop (um MSI GE60, com uma GeForce GT 750M) sob o lubuntu 13.10. Pela informação que eu juntei, eu tive que usar o Bumblebee se eu quisesse usar o GeForce.

Eu o instalei usando instruções encontradas aqui e aqui . Eu atualizei os drivers para nvidia-319-updates .

Mas, apesar disso, quando tento executar primusrun glxgears , tenho a seguinte saída:

Eu tentei olhar para /var/log/Xorg.8.log , mas não encontrei nenhuma informação útil lá (tentei procurar por erros, mas tive o seguinte resultado:

 cat /var/log/Xorg.8.log | grep EE
    (WW) warning, (EE) error, (NI) not implemented, (??) unknown.

 [  1665.892] (EE) Server terminated successfully (0). Closing log file.

Eu também tentei mudar o KeepUnusedXServer para true para ver se eu tinha outras saídas, mas a única que eu tinha no syslog era a seguinte: glxgears[2086]: segfault at 0 ip 00007f5ee5d41547 sp 00007fff71783f40 error 4 in libGL.so.1[7f5ee5d1c000+41000] .

Além disso, quando executo primusrun nvidia-settings , tenho uma mensagem informando que não estou executando o driver nvidia. Mas optirun nvidia-settings -c :8 mostra as configurações.Ela, ainda produz o mesmo tipo de log em syslog .

Apenas no caso, o (descomentado) bumblebee.conf :

 [bumblebeed]
 VirtualDisplay=:8
 KeepUnusedXServer=false
 ServerGroup=bumblebee
 TurnCardOffAtExit=false
 NoEcoModeOverride=false

Agradecemos antecipadamente pelas respostas!

Bem, de repente começou a funcionar. Eu não fiz nada de especial além de atualizações e upgrades. Não sei o que consertou.
