resolvido pela reinstalação com o sistema operacional de 32 bits
Mudei do Win 8.1 64bit para o Ubuntu 14.04 64 bit com uma nova instalação do DVD. Tudo está se movendo lentamente com o desempenho. Gráficos são justos, mas quando digo desempenho quero dizer, uma média para abrir qualquer aplicativo, eu posso contar até 10 Mississippi antes de carregar, por exemplo, firefox, LibreOffice, Chrome, etc. As ferramentas do sistema demoram cerca de 5 segundos. O login leva cerca de 25 segundos. O tempo de inicialização é ótimo em menos de 20 segundos. Alguma idéia?
Aqui está minha configuração:

resolvido pela reinstalação com o sistema operacional de 32 bits
como eu vejo você tem apenas 2GB de RAM como esse direito ok verifique se você instala o ubuntu 32 bit não 64 bit
se você fizer isso pode ser o seu problema de placa de vídeo como ele pode ser velho para executar alta gráfico que encontrou em unidade ou tem problema em drivers para ele como você deve usar driver proprietário não abrir código-fonte para o seu vga ou em frente
então tente duas configurações do gerenciador de dispositivos se o mesmo problema ainda for encontrado e você tentou todas as soluções acima, então tente instalar o Desktop Environment leve que não tenha gráficos como o lxde ou mais leve que ele
sudo apt-get install lubuntu-desktop
faça login neste DE para ver se ainda se sente lento ou não
