I have a Acer Aspire 5741G and I installed Ubuntu 16.04 LTS recently. I have windows 7 pro as the other OS (dual boot). I get really slow boot times. It takes roughly 2 minutes to show all the icons on my desktop.

When I try running systemd-analyze , it shows around a minute mostly (screenshot attached). Screenshot for systemd-analyze blame also attached. Can the boot time be possibly reduced? Also, my screen flashes few times before the purple loading screen while booting. After some searches, people said it has something to do with the graphic card. Can I make this right?

  • Is sda7 your root partition? Do you know how to fsck -f / or fsck -f /dev/sda7 from recovery mode/root access? – heynnema Dec 26 '16 at 16:46

Lets check the file system to make sure there aren't any errors.

  • boot to the GRUB menu
  • choose Advanced Options
  • choose Recovery Mode
  • choose root access
  • type sudo fsck -f /
  • run fsck more than once if there were errors
  • optional
    • open terminal from the Unity dash
    • type grep sda7 /var/log/syslog*
    • look for errors
    • copy/paste output into paste.ubuntu.com and give us the URL
  • type reboot

  • paste.ubuntu.com/23693642 (link for the grep command). Here's the link to the fsck command- imgur.com/a/3mjbM (I used imgur as I don't know how to add images here. Sorry) – abdrk00 Dec 27 '16 at 10:55
  • Edit your question to include the output of sudo blkid and cat /etc/fstab and lsblk and swapon – heynnema Dec 27 '16 at 15:59
  • ps: Make sure to put @heynnema at the beginning of any new comment directed to me, or I might not see it. Let me know when you've done the above commands. – heynnema Dec 27 '16 at 16:13
  • The output screenshot has been added to the question. – abdrk00 Dec 27 '16 at 20:48
  • Everything looks fine. I'm at a loss. Is your BIOS up to date with version 1.23? If not, go to acer.com/ac/en/US/content/support-product/2058?b=1 and download the newest BIOS from there and install it. I'd recommend making a good backup of your important files before installing it. It never hurts to be safe. – heynnema Dec 27 '16 at 21:04
