Reading Start-up Screen

I have the same problem as another poster with being able to read super-sonic speed of the info on my start-up screen but don't want to hijack his thread so here is mine .....

Aravisian gave a great explanations as to why you can't slow down the speed of the info given and two terminal commands for being able to read the info at your leisure .....

Here is what I found out when I tried these to commands ..... first one was .....

...... journalctl -b ..... which for me contained 3599 separate entries for today's date of June 6th 2023 ....

The second one was .......

...... lsblk ...... much more manageable at just a few lines which I will post the results here ......

mike@mike-ROG-Strix-G731GT-G731GT:~$ lsblk
sda 8:0 0 931.5G 0 disk
├─sda1 8:1 0 476M 0 part /boot
├─sda2 8:2 0 2.8G 0 part [SWAP]
├─sda3 8:3 0 209.6G 0 part /
└─sda4 8:4 0 718.7G 0 part /home
nvme0n1 259:0 0 238.5G 0 disk
├─nvme0n1p1 259:1 0 260M 0 part /boot/efi
├─nvme0n1p2 259:2 0 16M 0 part
├─nvme0n1p3 259:3 0 237.4G 0 part
└─nvme0n1p4 259:4 0 850M 0 part

As to the first one there were several lines in red and more in yellow but as the strings were way to long or numerous to post here ..... some of the red ones were things like "failed to launch sensor" and stuff like that .....

Only one that concerned me was about my model of MB maybe leaking info ..... I read the website attached for reference but as I'm not planning on changing my MB and I didn't see any means to correct this or at least the website didn't mention any solution that I could see I'm stumped except to ignore it ????? .....

Some of the yellow ones were this or that ..... process didn't start or the log didn't have access to something .....

My questions are is this log just for 6/6/2023 or are other days included ...... is there a way to reset this log so it isn't 3599 entries ???? ..... can it just show red or yellow entries instead of all of them ????? .....

Is the info I posted from the terminal ...... lsblk ..... above normal or look OK ???? ......

Gday @Frog ,

I'm not sure by date, but you can limit the output lines:

journalctl -n 25

eg: Gives the last 25 lines, or 200 for 200 lines

You can also filter the objects via name

journalctl -u service_name

Hope this helps.

I've read the info given in this website and tried some of the commands that I understand .... one of them was to show 2 days worth of the journal which produced 13,011 lines of info .....

A question I have and can't find the answer in that website is how do you clear all the previous days information ..... surely if the journal keeps all that info from the day I bought my computer to now there must be a ton of unwanted material taking up space .....

I noticed tat the same stuff from day 1 was repeated for day two which is kinda redundant ....

Hint: vacuum
you can limit the file size.
Open journald.conf file.

sudo -H gedit /etc/systemd/journald.conf

Remove the "#" from the line #SystemMaxUse=
& Place the size you wish, to the comment.
Eg: #SystemMaxUse=100M will limit the file size to 100 Mb


OK ..... I did the ..... #SystemMaxUse=100M will limit the file size to 100 Mb ..... and ran ..... journalctl -b ..... again and nothing changed so I took some photos to show today's log ..... but only the 1st and last page as there i just way to much info ..... and the entries are VERY long but I did copy the first and last in their entirety if you want to read them ....

It could be I'm not making myself clear .... I want to know how to clear the logs or if you can as it states they are from Sat. 2023-4-29 till today .... that is an awful lot of data being generated each day that appears to take up a lot of bytes ..... can they be cleared as they appear to just be saying the something .....

This is very confusing for me and I hope I'm not opening a rabbit hole I don't want to travel down .....

Am I better off just leaving it alone ?????

sudo journalctl --vacuum-time=2d

The above will clear everything but the last two days. You can change the number of days. For example: Five days:

sudo journalctl --vacuum-time=5d

Thank you sir ..... I think Ocka tried to explain that to me but it never got past the cobwebs in my brain .... still trying to remember what I had for breakfast .... :sunglasses: :laughing: :laughing:

OK completed now will I have to do this again or will it only save 2 dayes from now on .....

Hummmmm ... now it says from 2023-03-22 to today .... did I do something wrong ????? ....

Sorry may have been my bad instructions.
It should look like this
SystemMaxUse=100M << without he #
So this will remove old entry's as new one's are made.

To Vacuum=remove/delete.

journalctl --disk-usage

To check file size.


No you told me to delete the # but being the lazy sot that I am I just copied your eg and pasted that ..... DUH ..... :thinking: :rofl:
