My pc works fine. I can boot it up properly but it always decides to get stuck on a purple screen for around 15secs. After this text "ubuntu" with the dots come up in a low-ish quality and then I can finally log in and do what I want.

Your computer is booting Ubuntu during those 15 seconds. You can see a detailed log of what was happening during boot by viewing the file /var/log/syslog

What should I look for in it?– user874212Sep 24, 2018 at 12:25

2Each line should contain a timestamp which gives you a view of what things were happening during boot. You can also look to see if anything is blocking the boot process like a network timeout or waiting on a piece of hardware. If you're not running an SSD a boot time of 15 seconds seems very reasonable. Before boot you can also hold down
Shift
and press E to modify the boot command in Grub removing the "quiet splash" options which will show you while booting exactly what is happening instead of showing the splash screen. Sep 24, 2018 at 12:29 -
From
/var/log/syslog
I found a long line of\00\00\00\00
. The line above this wasSep 25 23:27:05 gottaslay kernel: [ 6168.928624] audit: type=1400 audit(1537907225.320:90718): apparmor="DENIED" operation="ptrace" profile="snap.discord.discord" pid=4706 comm="Discord" requested_mask="trace" denied_mask="trace" peer="unconfined"
and underneathSep 25 23:28:07 gottaslay systemd-modules-load[290]: Inserted module 'lp'

Sep 26 15:51:51 gottaslay systemd[1]: Stopping Tool to automatically collect and submit kernel crash signatures...
It seems module "lp" has something to do with this?Sep 26 15:52:39 gottaslay systemd-modules-load[292]: Failed to find module 'lp'
