    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?
     
  2. 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 ?

    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.

    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 ...

    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.:D :argh:

    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.

    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
