[SOLVED] Slow boot

[antony_css]

I am using hardy LTS...
booting have been slow for months and i don't know why...
recently I installed bootchart and it generated this chart:

It takes 2min to boot!!!:(:(:(
Do I need to "trim" some sort of processes and services? And how?

P.S.: Sometimes it takes so slow that it affects loading of applets after log in, such as the "The panel encountered a problem while loading "OAFIID: GNOME_MultiLoadApplet" prompt. Is this because it exceeds the loading time limit?

Here is the dmesg message during boot time:

There are many things that goes to improve ur boot performance.

System-->Preferences-->Sessions
Uncheck services not required.


sudo gedit /boot/grub/menu.lst
Then search for the line that reads timeout and change the value to read
either 1, for a one second countdown, or 0, to disable the boot menu
completely.


sudo gedit /etc/init.d/rc
Change CONCURRENCY=shell. This will enable multicore processors to run startup scripts in parallel.

Reboot and see the difference.

BTW what is ur hardware specs?

You have 2 things apparently taking a long time - readahead and linux-restricted.

From your dmesg you can see that there is a 70second lag between lines 363 and 364 - do you have a disc referenced in fstba not connected at boot? That would be a first guess from me

Have a look in you xorg log to see if there's anything in there as well.

Have a look in you xorg log to see if there's anything in there as well.
Could you tell me what is "xorg"? Is that a folder/file that I can browse in nautilus?
Or anything like a conf file?

Sorry I am just a newbie...

System-->Preferences-->Sessions
Uncheck services not required.

This was done well before the problem comes.
I unchecked following services:
Bluetooth manager
Evolution Alarm Notifier



Code:

sudo gedit /boot/grub/menu.lst

Then search for the line that reads timeout and change the value to read
either 1, for a one second countdown, or 0, to disable the boot menu
completely.

Sorry, I am using Ubuntu-XP dual and I just need that.



Code:

sudo gedit /etc/init.d/rc

Change CONCURRENCY=shell. This will enable multicore processors to run startup scripts in parallel.

Reboot and see the difference.
I will do this but I don't think this will work.
According to the bootchart, most of the boot time is wasted on delay on I/O wait and reading hard disk, so parallel running may not work...


what is ur hardware specs?
Well, I don't know how to show these... Which command should be run on the console?

[antony_css]

I looked into the /var/log folder and I found the file Xorg.0.log
It is a bit messy...:confused:

Besides, I ran "locate fstba" in the terminal and it returns nothing.

mine is a hp box with 4 card readers...
I think this is the "SCSI removable disk" that is listed in dmesg.

Your issues are nothing to do with your menu list.

Run this from a terminal - run it twice - replace EE with WW the second time - post both results here please


cat /var/log/Xorg.0.log |grep EE

Those 2 commands will give you any errors or warnings xorg gives during start.

Run this command - it will show your hardware


sudo lshw -short

xorg - deals with your x window - it's afaik the basis for what you see and underlies your desktop manager

[antony_css]

all done.

[antony_css]

Sorry I have to go to bed now... I am in +8 time zone.
I will read your reply tomorrow...
thank you.

[Elfy]

Look ok to me, I assume that you don't have any other problems.

Can you post the result of this here please


cat /etc/fstab

BTW what is "readahead-list" that is shown in the bootchart? Is it required? How can I trim it?

[antony_css]

I found this thread by searching "readahead-list":
http://ubuntuforums.org/showthread.php?t=254263&highlight=readahead-list

This is pretty old... Should I have a try?

[antony_css]

Done it. It saves 1:23.

"readahead-list" takes most of the boot time.:(


BTW firestarter was run unsuccessfully for three times, until it finally detected the device ppp0. Is the slow booting related to this?

Yes, pls try. The method is tried and tested.

jdong is an admin - I can't see him leaving a dodgy tutorial about

I doubt if firestarter is causing the issue - you might like to know that UFW is much easier to use than firestarter

In the string
cat /var/log/Xorg.0.log |grep EE

the .o. in Xorg.o.log should be a zero: Xort.0.log
at least on my machine with U 8.10.

ADDENDUM:
After posting, it seems the message I was responding to was removed.
