Slow booting of Ubuntu?

[swangnation]

Just installed Mate to 64GB flash drive, yesterday.
Install was very slow as writing to flash drives is very slow.

First boot of flash drive was 3 min & 55 sec which seems about right.
But it turns out the systemd-analyze firmware number is from first boot, so on my warm reboots that kept getting much larger.

But after making the changes I posted in #48 & #50 boot time dropped a lot.
I had printer on which slowed it a lot. But when I turned printed off, it crashed?

Not sure if some of improvement was internal optimization as you reboot.
but udsisk when from 35s to 11s to 5 sec.
network entry went from 12.5s to 6.8 sec to 4 sec.

I did add noatime to mount of / and added entry to mount tmpfs in RAM to reduce writes.

Last test reboot was about 21s to login. and it reported 8.2s to graphical screen which seems about right.
Firmware was up to 23minutes, but that was 3 reboots and editing.

Boot time of Mate from slower flash drive now seems pretty quick.

can you post more details about #48 please.

Details were in #50.

guys, i just ran
p

arted /dev/sda print

i got the following output

Model: ATA SAMSUNG HM251HI (scsi)
Disk /dev/sda: 250GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags: 

Number  Start   End    Size   File system  Name                  Flags
 1      1049kB  538MB  537MB  fat32        EFI System Partition  boot, esp
 2      538MB   250GB  250GB  ext4

does that look right to you guys? Anything worth changing?

That is a standard UEFI install.
A bit more advanced is to separate system from your data or have a separate /home partition.

And many of us go one step further and use data partition(s). But then you need to understand, mounting, editing fstab, ownership & permissions.
Having /home as a partition does all that automatically if you set it up during install.

You can create a new /home partition with step by step instructions which cover the details.
To move /home uses rsync- Be sure to use parameters to preserve ownership & permissions

I like to keep / at 25 or 30GB but have all data in my data partition so / only actually uses about 7 GB.

don't know how to say this but i just back tracked on some of the things I've looked at done to try and make my boot up a little faster and i realized i made some basic errors. In the fstab file, instead of having/swapfile none swap sw 0 0

it was /swapfile non swap sw 0 0. Maybe this makes a difference, better to assume it does.

but also i didn't edit /etc/initramfs-tools/conf.d/resume, and now i remember why. It's because that file is empty. So what file is being used instead? or where is the file i need to edit?

I'm actually beginning to think that all these problems are being caused by the initial installation of ubuntu which i didn't do and that maybe it might be a good idea to reinstall, however i cannot boot off a usb or cd on this laptop.

[oldfred]

If you cannot boot USB, you may need to turn on in UEFI allow USB boot or full USB access type setting.
Or if UEFI Secure Boot is on, that may also prevent USB boot as not secure unless you specifically allow it.
And they USB flash drive has to be correctly configured so UEFI will see it as a boot option in the one time boot menu, often f12 or f10.

The drive that is listed in the display in post #63 is a 5400 rpm drive. Have you considered an SSD? You could vastly improve boot time just by changing to SSD.

[swangnation]

your right dennis n, an ssd drive will be quicker but then if I'm going to start spending money i might as well put together a pc. In any case i think i'll give this bios a tickle and see what happens. Is there a thread on here that is best for asking questions about bios and uefi?

[oldfred]

You can start a new thread with that in title.
Lots of info on UEFI in link in my signature below and further links in it.
UEFI/BIOS varies by vendor, best to check what your manual and vendor's site say for your specific model.

[oldrocker99]

If you have problems with UEFI, try Legacy. It's been my own experience that using UEFI, which has kept grub from installing, leaving an unbootable computer, for me.
