I recently installed Ubuntu 15.10 in dual boot with Windows 10. Since the installation, Ubuntu is taking about 1 minute to boot. Before the login screen the plymouth boot splash screen does not show up. Instead a black screen is displayed for about 20 seconds. So I figured it may be the problem but I am just guessing.
What I did was :
- Ran systemd-analyze blame. Found the plymouth quit-wait service taking 20 secs. So masked it by running systemctl mask plymouth-quit-wait.service.
- However no improvement in boot time.Although the log does not show the plymouth-quit-wait.service it is taking the same amount of time.
Ran systemctl mask plymouth-quit-wait.service again. This is the file here http://pastebin.com/QhBrGt2x
- Also ran the bootup-repair utility but no help.Boot time is the same. This is the file generated by it here http://paste.ubuntu.com/15381960/
Note: I have 8 GB RAM and a HDD. My Windows 10 also takes similar time to boot. I also installed the Gnome-Desktop utility
Any help or advice is appreciated. Thank you.
