ubuntu startup applications

System-Preferences-Startup Applications
Is it safe to remove some:
Bluetooth manager----I do not have
Evolution alarm notifier--I use thunderbird
Power manager----My PC is a desktop
Does removing the check and disabling startup make the PC boot faster as in Windows?

 

In a word... No. Those are desktop startup items, not system ones, and removing them will not make a big difference in your boot time. System startup items can only be modified from the command line in current versions of Ubuntu.

 

Even if you remove some, you will be removing the convenience of Ubuntu at minimal gains.

 

Yes, it's certainly safe. Have always been doing it.

 

On my dual quad XEON machines I get nine second boot time on average with all these installed.

 

Do you count seconds(which I do) or use bootchart to find out how many seconds your boot time takes.Do you start counting after the bios message or after you push the start button.

 

Install bootchart and then reboot. (In case you are dual booting and have a grub menu, just select the kernel and hit enter).I think bootchart will require openjdk to also be installed, in which case it's a big download - probably not worth it as the boot time for your machine looks fine to me (you said about 25 secs).
Mine is 23 secs. on a quad core 2.66Ghz system but there is a 5 secs. delay for bios handoff, something that affects Intel DP45SG motherboards. Desktop is instantly there after login.
Maybe linuxforall can tell us if the number of partitions on a disk will lengthen boot time i.e. just / and swap vs. / /home swap /backup etc.
Also maybe Vbox too as drivers need to be loaded ?

 

Ocky, I 20GB for Ubuntu /, 12GB for swap and rest of 2TB is data, all ext4. I use Intel motherboard as well, the S5520SC to be specific.

 

I already have java installed.So I installed bootchart and got the results.I will post it on the
Ubuntu forums.

 

I have seen it. Who's complaining ? I should be the one to feel disappointed due to the 5sec+ delay caused by bios handoff affecting my motherboard. Very slow for Lucid considering my thruput @75MB/sec. - but I am still happy, it's a really minor thing and as Mrk once asked me "how many times a day do you boot up".
Here a snippet.

 

Mine is 46

 

It's all totally meaningless as far as I am concerned. My bootchart for Karmic on my second HDD shows 1:07 secs. (deduct 45 secs from this, the pause for login and deduct further 5 + secs. for bios handoff bug means a boot time of about 17 secs.) Thruput = 125MB/sec.(Lucid 75MB/sec. same machine same disks). So you can see how (for me) this is all a waste of time and I will uninstall bootchart today (those log files will mount over time - one on every boot, unless you delete them regularly). Funny thing is Lucid seems faster than Karmic. Here is final chart showing Karmic.

 

I have the same thingie. An older machine boots in 15 sec, my latest and greatest in 25, due to 13 second delay, part of which is ureadahead, but I guess it's HW initialization as well, but ... who cares.

However, I'll write about this ...

Mrk

 

I already uninstalled bootchart.The average bootup time is about 20 sec on the Ubuntu forums.So far I am happy with the boot time compared to Windows.

 

Due to this perhaps - like my delay .. https://bugs.launchpad.net/linux/ bug/275351
Edit:-
This is raising my blood pressure, systolic, to 160mmHg and you know what that implies.

 

Ocky try flashing your BIOS to latest.

 

I do. And if you manage that much, you must be either very smart or got a high blood pressure anyhow. Now, OT, I don't think that bug relates to my case, and I don't think I'll be troubleshooting that much ... but if, then, well, thanks.

Mrk

 

OT - 0.214 bar, not quite so onerous and no fainting !
(OK, no more, I am exhausted).

 

Lucid runs really well on my T61...

Nick, yes I got 15 sec on T61, 27 sec on T42 and 25 sec on RD510 ...
Mrk

 

Just had another look at the logs to see whether there is something else that might slow down booting and came across this one:-

[ 7.465320] device-mapper: dm-raid45: initialized v0.2594b
[ 12.634690] EXT4-fs (sdb1): barriers enabled
[ 12.643512] kjournald2 starting: pid 506, dev sdb1:8, commit interval 5 seconds
[ 12.643588] EXT4-fs (sdb1): delayed allocation enabled
[ 12.643591] EXT4-fs: file extents enabled

There seems to be a 5sec. gap between this one and the next entry.
Is this normal ? I don't use Raid at all.

Edit: Should I just uninstall the dmraid package ?

 

I have never used Raid, so would it be safe to run these commands (or can I just uninstall dmraid package) ? ...

sudo dmraid -E -r /dev/sda
sudo dmraid -E -r /dev/sdb
sudo apt-get remove dmraid

dmraid -r shows no raid disks
