kernel boot parameter - diskrod - 07-08-2019

I recently upgraded to a HP laptop and my profile has changed. I'm a novice when it comes to Linux Lite but I'm trying to learn new stuff.  I'm confused about "add the kernel boot parameter" as shown below.  How do I add it? I'm able to get into the terminal and enter the first sudo line but after that I'm lost. Any help is appreciated. I have a slow boot time of six minutes which I'm trying to change with the following:
  • sudo nano /etc/default/grub
Then add the kernel boot parameter: video=SVIDEO-1:d, so it will look like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=SVIDEO-1:d"
  • sudo update-grub
  • sudo reboot

You are copying someone else's solution from another thread, ignore it. You need to start from the beginning. Open a Terminal, run the following command and paste the results here:

Code:
systemd-analyze blame

Now:

Code:
systemd-analyze critical-chain

and:

Code:
systemd-analyze

then attach /var/log/boot.log to your post.

Re: kernel boot parameter - diskrod - 07-09-2019

I entered what you mentioned in the terminal and I got this:
/var/log/boot.log
bash: /var/log/boot.log: Permission denied

Read very carefully the instructions, I asked to attach it to your post, not paste it.
