Estou escrevendo perguntando sobre um problema muito estranho que tenho com a minha instalação do Ubuntu. Ao inicializar, notei que demoraria muito para chegar à tela de login onde eu poderia inserir minha senha. Depois de fazer algumas pesquisas, eu encontrei este artigo no AskUbuntu ( Como consertar o Ubuntu muito lento inicialização? ) e a melhor solução foi tentar olhar os logs para resolver o problema.
Eu olhei para os meus logs, e para minha surpresa houve algo que definitivamente chamou minha atenção ... algo que literalmente continuou o tempo todo enquanto eu arrancava quando fui tomar uma xícara de café.

Eu tenho bleepado coisas como os endereços SSID e MAC da minha rede, porque eles não devem importar tanto quanto eu sei.
Atualmente, estou executando um Intel Core i5-4440 em um MSi Z97 PC MATE com 8 GB de memória Kingston HyperX DDR3-1600 com o máximo de 1866 MHz com um Gigabyte R9 380 G1 Gaming Edition e um Asus PCE- Adaptador Wi-Fi n15.
Qualquer apoio seria muito apreciado!
