Hi guys, for the first time i've installed a Linux Distro (latest Fedora 19 with gnome3). I like it very much but i want to improve the boot time. I think i can disable some useless service (for me) like bluetooth or wi-fi module (i use ethernet cable) and there are some errors too. Please answer with easy to understand language and examples of command to launch because i'm a newbie :)

This is what is shown with dmesg command (sorry i can't upload/attach it because it's first question here): ("long gap" are 8-11, 13-37, 37-271)

dmesg output can be found in fpaste.org

Anyone can help me? :)

The main problem now is the black screen hanging on boot for 10 secs after Fedora logo and right before login screen

I'm "in there" in about 56 secs (the motherboard takes 20s to load things and display O.S. list, so 36 secs to load), Before login screen (and after the Fedora logo disappear) it shows me a black screen without actions (apparently) for 10s. I think there are some problems with ipv6 on boot.

If the problem is the time taken by plymouth-quit-wait.service, then take a look here:


It was told that removing /var/log/journal fixes the problem. Indeed, it did for me.

Otherwise, I don't understand what is the problem here.

This indeed decreased my boot time ... WOW about 20 secs.. !

NikTh ( 2014-01-31 19:40:35 +0000 )edit

What was your boot time? :)

skytux ( 2014-01-31 20:39:54 +0000 )edit

41 secs, after I removed /var/log/journal/ it is 21 secs . Counted with systemd-analyze before and after - Fedora 20 !

First of all, I see that plymouth-quit-wait.service is still runing during boot, so please execute (as root): systemctl mask plymouth-quit-wait.service (this will disable this service).

More to that, according to your question do (all commands as root):

  • If you don't need dynamic firewall: systemctl disable firewalld.service
  • If you don't use lvm (check this by (as root) lvs, and post result here): systemctl disable lvm2-monitor.service and systemctl disable lvm2-lvmetad.service
  • systemctl disable avahi-daemon.service
  • systemctl disable dmraid-activation.service
  • systemctl disable livesys-late.service
  • systemctl disable livesys.service
  • systemctl disable sendmail.service
  • systemctl disable sm-client.service
  • If you don't need to connect (as a cient) to NFS server or NIS server, then disable: systemctl disable rpcbind.service
  • If you don't need Bluetooth: systemctl disable bluetooth.service
  • If you don't need time synchronization: systemctl disable chronyd.service
  • If you don't need Plymouth (this graphic-animation boot) systemctl disable plymouth-read-write.service and systemctl disable plymouth-start.service

If for some reasons, after reboot you still see any of disabled by you service in systemd-analyze blame, then redo command, but replace disable with mask, eg: systemctl disable rpcbind.service doesn't work, rpcbind is still running, then: systemctl mask rpcbind.service.

Again, all command execute as root (or at least by sudo).

After you done, and none of this service is running again, update your question with results from; systemd-analyze; systemd-analyze blame

Hi, thanks for reply. I've disabled a few services you wrote, but i didn't get any reasonable improvements. Is Thunderbird related to sendmail? or it doesn't need that service? Another thing: is it normal to wait 10 seconds (black screen) after that Fedora logo disappears and before the login screen?

panguro ( 2013-10-06 16:33:42 +0000 )edit

You don't need sendmail for using any MUA like thunderbird. And no, it is not normal.

Artur Szymczak ( 2013-10-06 16:42:56 +0000 )edit

Ok, then, what it could be? other than cutting off the 10 sec black screen i think there's nothing left to do to really improve the boot time.

Once you have a list to work,

with the output Artur Symczak asked for - i'd prefer the command output the other way around: systemd-analyze blame;systemd-analyze

You can disable them like this.

NOTE: This example works for me, but might not be applicable to your system!

for serv in ip6tables bluetooth \
    sendmail exim \
    livesys livesys-late \
    mdmonitor mdmonitor-takeover \
    lvm2 lvm2-monitor
    systemctl stop $serv.service
    systemctl disable $serv.service

These are common victims for my system, so i have them disabled upon first login.

Edit & update: According to your output, i'd applied them this way for you:

for serv in fedora-loadmodules plymouth-quit-wait \
        bluetooth systemd-fsck-root \
        avahi-daemon lvm2-monitor
    systemctl stop $serv.service
    systemctl disable $serv.service

lvm2-monitor and avahi-daemon might cause an issue - i dont know. If it was my system, id run this, but then its not mine - you do at your own risk.

Mmm i'd prefer to not risk! i think lvm2 and plymouth are necessary. Do You know a secure way to completely disable ipv6 on boot?

panguro ( 2013-10-04 19:29:44 +0000 )edit

You could always erease any ip6tables from your system, however, just disabling should suffice.

yum remove ip6tables vs. systemctl disable ip6tables.service

If you dont have a LVM setup, you can savely remove lvm2-monitor, however i'm not sure how much it affects raid systems...

sea ( 2013-10-04 20:08:20 +0000 )edit

First command doesn't work, the second one "systemctl disable ip6tables.service" seems to disabling it, but when i reboot it loads the same things and it takes exactly the same time to boot up. BTW thanks for replying :) ..other solutions?

panguro ( 2013-10-04 20:34:18 +0000 )edit

What do you mean by "doesnt work".. is there no package to remove or didnt you run yum remove ip6tables as root?

sea ( 2013-10-04 21:16:35 +0000 )edit

no package to remove
