O Ubuntu leva muito tempo para inicializar depois que eu iniciei com o win7

Question

Quando eu tenho apenas o Ubuntu 16.04, é muito rápido e tempo de inicialização também foi muito menos.Mais tarde eu instalei o Windows 7 por dual boot (e GRUB reparado) .Depois que o Ubuntu leva muito tempo para arrancar, mas Win 7 botas instantaneamente.Depois de executar dmesg estou dando a última parte.Por favor, sugira uma maneira de resolvê-lo.

Answer 1

Eu vejo vários erros, alguns menores, alguns que podem causar inicialização lenta ...

driver lp (menor)

[   12.987888] lp: driver loaded but no devices found
[   13.047867] ppdev: user-space parallel port driver

Em terminal ...

• gksudo gedit /etc/modules
• coloque um # na frente do lp para desativar o driver não necessário do lp
  • altere lp para isso ... #lp
• salva o arquivo e sai do gedit

erros do sistema de arquivos? (possivelmente maior)

[   15.717083] EXT4-fs (sda6): re-mounted. Opts: errors=remount-ro
[   16.228800] systemd-journald[231]: Received request to flush runtime journal from PID 1

Vamos verificar se há erros no seu sistema de arquivos ...

• inicialize no menu GRUB
• escolha Opções avançadas
• escolha o modo de recuperação
• escolha Acesso raiz
• no prompt #, digite sudo fsck -f /dev/sda6
• repita o comando fsck se houver erros
• digite reboot

IPv6 (possível lentidão)

[  108.290006] IPv6: ADDRCONF(NETDEV_UP): ens2: link is not ready
[  108.297330] r8169 0000:03:00.0 ens2: link down
[  108.297373] IPv6: ADDRCONF(NETDEV_UP): ens2: link is not ready
[  267.122970] perf interrupt took too long (2501 > 2500), lowering kernel.perf_event_max_sample_rate to 50000

Defina o perfil de rede para "Conexão com fio", guia IPv6, Método = Ignore

• nota: volte para Automatic depois de substituir o driver r8169 e veja se esse problema desapareceu

Driver Ethernet (possível lentidão, problemas de conexão)

network description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller
driver=r8169
speed=10Mbit/s

• buggy r8169 driver ... substitua por r8168-dkms
• apenas 10Mbit velocidade ... cabo ethernet ruim ou switch / hub

Em terminal ...

• sudo apt-get update
• sudo apt-get install dkms r8168-dkms
• reboot
