Eu consertei isso instalando dbus-x11 (Clique para instalar)
ou
sudo apt-get install dbus-x11
Eu tenho um sistema Ubuntu recém-instalado ao qual eu adicionei o LAMP e o emacs.
Tudo parece estar funcionando, com exceção do emacs e do Thunderbird que lançam erros semelhantes:
WARNING: Application calling GLX 1.3 function "glXCreatePixmap" when GLX 1.3 is not supported! This is an application bug!
failed to create drawable
(thunderbird-bin:4822): GConf-WARNING **: Client failed to connect to the D-BUS daemon:

No entanto, o emacs funcionará se eu o sudo e o dbus estiver rodando, veja abaixo:
750 ? Ss 0:00 dbus-daemon --system --fork --activation=upstart
1302 ? Ss 0:00 //bin/dbus-daemon --fork --print-pid 8 --print-address 10 --session
1893 pts/0 S 0:00 dbus-launch --autolaunch 5083cb999a9b950abece203100000005 --binary-syntax --close-stderr
1894 ? Ss 0:00 //bin/dbus-daemon --fork --print-pid 5 --print-address 7 –session
Alguém tem alguma ideia?
