Can I Remove Startup Applications


I have some 20 or so startup applications and I need to know if I can ‘uncheck’ any of them to allow faster boot up, etc.

(Incidentally, does ‘unchecking’ them mean that they will stay in the Startup App Pref screen and just not startup so that I can ‘check’ them again in the future? I haven’t attempted to do anything yet as I am unsure whether they will ‘disappear’!)


Which distro/version

And which “startup applications” ?

Hi, Thanks.

Ubuntu 16.04 LTS

Accessibility Profile Manager Indicator
Backup Monitor
Certificate and Key Storage
Desktop Sharing
GNOME Software
GSettings Data Conversion
Indicator Application
Mount Helper
Orca screen reader
Personal File Sharing (Launch Bluetooth ObexPush sharing if enabled)
Personal File Sharing (Launch Personal File Sharing if enabled)
PolicyKit Authentication Agent
PulseAudio Sound System
Secret Storage Service
SSH Key Agent
Update Notifier
User folders update
Zeitgeist Datahub

The laptop is only used for simple stuff, such as web browsing, and all updating is disabled (for reasons I won’t bother going into here).

The system takes over two minutes to boot up and into Firefox. The first minute of that is a blank screen before seeing anything.


I seriously doubt if any of those services are slowing the boot sequence … they’re all pretty much loaded after login.
What’s the output from

Does this help?


Can you run:

dmesg > ~/Desktop/dmesg.txt

you’ll then find a file on your desktop called “dmesg.txt” … can you host that file online somewhere such as
then provide us with a link so we can download it and look for any errors.

PS The ‘Notification’ for this thread doesn’t seem to work.

I can see no major problems in your dmesg output besides some IPv6 duplicate warnings.

If you don’t need it, you could see if disabling IPv6 helps

If that doesn’t help, can you explain:-

The system takes over two minutes to boot up and into Firefox

How long to boot, and once booted how long to start firefox?

Oh and in answer to your original question … this for sure can be disabled
GNOME Software


The boot up I have just done takes approx. 1:40 - 1:50 to boot to the desktop and then a further 40 - 60 secs to run up Ff and load the first page. (30-40 is Ff loading.) The uncertainty of the figures is the fact that it’s not always certain exactly when the desktop/Ff is ready, as sometimes clicking on an app/link doesn’t always work first time. So it could be as short as around 2:30. (My stopwatch said 2:40.)

At this point no startups have been disabled.
