Por quê?
Encontrei esta questão relacionada . De acordo com sua resposta aceita, eu deveria editar /etc/X11/Xwrapper.config
da seguinte forma:
allowed_users=anybody
needs_root_rights=yes
Eu fiz isso, mas isso não muda nada para mim.
Os comentários parecem sugerir que startx
está quebrado no Ubuntu. Por que é que? Se for esse o caso, talvez a resposta à minha pergunta original seja "startx não é mais possível porque ...", ou "tornar isso possível teria ... desvantagens" ou algo assim?
