Atualmente estou executando no Elementary OS Freya (baseado no Ubuntu 14.04)

Answer 1

O problema que você está enfrentando, na minha opinião, talvez seja devido à incompatibilidade do driver de gráficos ou à necessidade.

Parece que você está usando o bumblebee (visando a tecnologia Optimus da NVIDIA) para iniciar.

Tente isso por sua conta e risco.

Primeiro, decida qual placa gráfica você tem.

lspci | grep VGA

Isso me mostrou que estou usando "NVIDIA Corporation GF116M [GeForce GT 550M] (rev a1)" Então é a NVIDIA

Em seguida, instale-o em xorg-edgers PPA. Use a versão mais recente.

sudo add-apt-repository ppa:xorg-edgers/ppa
sudo apt-get update
sudo apt-cache search nvidia
Find the latest one (at time of this writing was 352)
sudo apt-get install nvidia-352
sudo apt-get install nvidia-352-updates

Neste processo, eu me livrei do Noveau e instalei o driver NVIDIA do PPA xorg-edgers. obs começou bem depois disso.

No entanto, houve tela congela de vez em quando e estou planejando explorar usando abelha em cima disso e ver se alguma coisa muda.

Boa sorte

Nota: instalando o driver NVIDIA obtendo diretamente da NVIDIA que falhou
