Xubuntu super slow startup

Question

computer specs

cpu: intel i7-7700k kaby lake
graphics: nvidia gfx 1070
ram: 16 gb
hard drive: 500gb solid state drive x1 and 250 gb solid state drive
wifi card: don't use

xubuntu version: 17.04 (latest ubuntu version)

how can i make my os startup faster. it currently takes 3 minutes and 21 seconds to startup. all other distros ive used normally don't take that long.

i ran the following command

systemd-analyze blame

prints

          9.434s NetworkManager-wait-online.service
          1.009s mysql.service

            26ms systemd-fsck@dev-disk-by\x2duuid-781C\x2dCC89.service
lines 1-23

i looked at this too

dmesg

prints

https://pastebin.com/UrVjtMUm

looks like

[   92.583751] kauditd_printk_skb: 12 callbacks suppressed

is causing the slow startup

more information

user@user-desktop:~$ systemd-analyze
Startup finished in 13.343s (firmware) + 5.114s (loader) + 2.405s (kernel) + 3min 473ms (userspace) = 3min 21.337s

-- and which version of Xubuntu are you running? — sudodus, Sep 06 '17 at 02:35
Xubuntu (as well as standard Ubuntu and the other community flavours too) should fly on that computer. Are you using any boot option, for example nomodeset? Have you installed a proprietary nvidia driver for the graphics chip/card? Could there be a problem with the systemd part of the startup? I don't know if there might be problems with the dual drive (HDD + SSD). — sudodus, Sep 06 '17 at 03:22
@sudodus I dual boot with windows 10 and I use grub2 as my bootloader. im using the default boot options. yeah normally linux does. xubuntu is the only distrobution that really struggles to load for me. ive tried elementary os, solus and no issues at all. — Chad Adams, Sep 06 '17 at 03:38
@sudodus I haven't. Do I have to completely reinstall my os to upgrade to that version? — Chad Adams, Sep 06 '17 at 05:37
You can install a proprietary nvidia driver into your current system. This link shows a solution rather directly, https://askubuntu.com/questions/896555/boot-problem-with-nvidia-gtx-1070 -- You can also browse the internet with the search string 'askubuntu nvidia 1070' (without quotes) and find several other links, for example one "megalink" with a lot of detailed answers, https://askubuntu.com/questions/162075/my-computer-boots-to-a-black-screen-what-options-do-i-have-to-fix-it — sudodus, Sep 06 '17 at 05:50
If you have installed a lot of program packages and spent time on tweaking, you had better install a new system, for example in an another [external or internal] drive or alongside the current system in the internal drive. Upgrading to a developing version will often cause problems. — sudodus, Sep 06 '17 at 06:08
@sudodus Yeah I spent a lot of time tweaking xfce :( if this issue would be regarding my graphics card wouldn't my screen not show up though? — Chad Adams, Sep 06 '17 at 06:14
@sudodus I tried to install the latest nvidia card. installation fails because it says its used by another system (im assuming because im dual booting windows 10 and i have the latest drivers on windows 10 already) — Chad Adams, Sep 06 '17 at 06:32
I think it is another issue, that stops installing the graphics driver. But if you are satisfied with the graphic performance (and the problem is limited to the slow startup) you should look somewhere else. Anyway, let us continue in the automatically created chat room :-) — sudodus, Sep 06 '17 at 06:40

line 820 seems to be a red herring. Where as lines 821-823 of your dmesg indicates that issue may be apparmor denning "/usr/sbin/mysqld".

To check this look in /var/log/syslog via grep apparmor /var/log/syslog. Temporarily downgrade apparmor's enforcement by running sudo aa-complain /usr/sbin/mysqld followed by a reboot and evaluate the output of dmesg. If the boot time improves restore enforcement by running sudo aa-enforce /usr/sbin/mysqld.

To properly configure apparmor for your use of mysqul see the Oracle blog post AppArmor and MySQL. For a deeper look at debugging apparmor see Ubuntu wiki - DebuggingApparmor

Adding an appropriate exception to /etc/apparmor.d/local/usr.sbin.mysqld may solve this portion of the slow boot.

That command gives me this https://pastebin.com/tYH2iUFz not really sure how to add an exception for that. – Chad Adams Sep 06 '17 at 06:12
You gotta use sudo apt-get install apparmor-utils to use aa-complaincommand – Chad Adams Sep 06 '17 at 07:11
Just tried that and it doesn't work https://pastebin.com/kJPwk8WV about the same load times. around 3 minutes – Chad Adams Sep 06 '17 at 07:15
@J.Starnes, You are welcome to the chat room :-) – sudodus Sep 06 '17 at 07:56
Since my answer is wrong. @ChadAdams, Would you add the output of systemd-analyze critical-chain and systemd-analyze plot > ~/plot.svg. to your question? – J. Starnes Sep 07 '17 at 04:58
