speed up linux mint boot process

pan64 · 11-01-2015, 07:47 AM

hi all, I have a linux mint, and the boot process is at about 45 seconds long and dmesg contains some strange lines (at least for me). For example here you can see almost 10 seconds delay. What does it mean?

Code:

I have no bluetooth devices at all.
and also:

Code:

[   37.982449] init: samba-ad-dc main process (1245) terminated with status 1

How can I completely disable samba-ad-dc?

This is a fresh new Linux Mint 17.2 Rafaela
thanks...

it all looks pretty normal to me.
obviously there's a few things you can uninstall, but don't break your system (and i doubt it will influence boot times more than microseconds)
45s doesn't seem too long... what are your hardware specs?

if linuxmint uses systemd, it's possible to create a bootchart. i forget how, just search "systemd bootchart".

pan64 · 11-01-2015, 10:31 AM

8 GB RAM, 3 cores amd with a normal HDD (no ssd).
bootchart was installed but somehow that did not work, so removed.

ondoho · 11-01-2015, 10:39 AM

oh sorry, i missed that you are pointing out delays.

10s between mounting the file system (or sth else?) and starting systemd... seems severe.
you should get more info on that.
systemd has another, non-graphical method that basically does the same: systemd-analyze (with lots of options).

the other thing, well, obviously i'd try to blacklist the floppy driver.
although i never had this sort of problem with it.

You could roll your own kernel to eliminate all the probing for hardware you do not have.

Maybe this article will help speed up the boot on your system

Oh yes, that would be the last thing I wanted to try, but probably there is no other way....

Some technical details:
MoBo: http://www.gigabyte.com/products/pro...px?pid=3587#ov
CPU: something like this: AMD Athlon II X3 450
2 HDDs, no SSD, wifi (no lan)
8 GB RAM
no CD/DVD/bluetooth/floppy/whatever
a relatively new ATI Radeon video.

To ondoho (or anyone):
how can I have more info?
blacklisting has no any effect.

The first 2 things I can think of to speed up booting are:
1) autologin - so you don't have to enter your password
2) Set Grub to boot after 1 second instead of 5 seconds, which is the default.

Code:

gksu gedit /etc/default/grub

Set these parameters:
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=1

And change the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet profile"
(Personally, I get rid of the word "quiet". But that is personal preference...)
What this does is profile your boot process to record what files are accessed and then sorts them according to how they are stored on your drive. Your first boot after doing this will be slow. Your next boot should be considerably faster.

You have to run

Code:

sudo update-grub

after making changes to the /etc/default/grub file.

Of course, you can always disable startup programs that you don't need.
For instance, when you don't have a scanner, you can disable saned. And if you never use bluetooth, you can disable bluetooth as well.
Other candidates are Apache2, PostGreSQL daemon, MySQL, virtual box (et al)

You can access the Startup Applications Preferences in Mint with Menu > Preferences > Startup Applications.
Unfortunately, Mint hides many of the Startup Applications from that GUI. But you can "un-hide" them by first running the command:

Code:

sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop

If you don't have bluetooth, you don't need an onscreen keyboard, you don't need to share files from your computer to other computers in your house, you won't be logging in using different languages, and you won't be logging in remotely, then you can respectively disable the following applications.
Bluetooth Manager
Caribou
Personal File Sharing
User folders update
Xhost +
If you don't have network devices you need to connect to, or Windows or Apple computers you need to interact with in your home, then you can disable some services also:
echo manual | sudo tee -a /etc/init/avahi-daemon.override
echo manual | sudo tee -a /etc/init/bluetooth.override
echo manual | sudo tee -a /etc/init/nmbd.override
echo manual | sudo tee -a /etc/init/smbd.override

check your swappiness with in terminal
$ cat /proc/sys/vm/swappiness
60
should be as above with swappiness=60

Try reducing the Swappiness.
in /etc/sysctl.conf
at the end of file add

# reduces the swappiness
vm.swappiness=10

save file restart computer will take the same
amount of time the first time. But with the amount
of ram you have it will be quicker.

I do this second after I update the system.

If you're not using samba you could uninstall it, for example, and I know I always remove avahi-daemon. You mention Bluetooth that's a few packages you could get rid of also.
